Description
Polyester Material Info:
Polyester resins are the most commonly used matrix in the marine and composite industry. These resins are styrene-based, flammable and catalyzed when combined with Methyl Ethyl Ketone Peroxide(MEKP). When working with these resins in large projects it is advised to use gloves and a chemical respirator to protect yourself from the fumes. These resins can be used with any type of fiberglass, carbon fiber or kevlar, as well as used over urethane foam and other sandwich core materials. These resins tend to be fairly rigid when cured and also more brittle than epoxy resins.
Sales Info:
All resins and gelcoats are sold without wax(sanding aid): If needed you can purchase surfacing wax separately for use on finishing coats. Unwaxed resin can be re-coated with little to no prep work but will leave a tacky surface. Mix the wax(sanding aid) with your resin only on your final coats in order to allow easy sanding. Catalyst/Mixing Ratios: All resin prices include catalyst. 1 Quart= 1ounce, 1 Gallon=2ounce, 5gal=6ounce. The amounts included can be varied based on your temperature and desired curing times. Cooler temperatures may require a higher % of catalyst than warm conditions. If additional catalyst(MEKP) is needed please order separately.
Shipping Info:
Because polyester resins are a flammable liquid, we are unable to ship these products by air freight. Quarts and gallons can be shipped via UPS ground with no extra fees with a maximum of four gallons per box. 5 gallon pails can be shipped via UPS ground only and require an additional $30.00 hazardous materials fee. Orders for multiple 5 gallon pails can be shipped by a common carrier(freight line) as well.
All resin prices include catalyst.
1 Quart= 1oz, 1 Gallon=2oz, 5 Gal=6oz

I have been purchasing this resin from illstreet for several years now. I make pens and duck calls with it, and my customers love the quality of the end product. I also use their pigments to color my pen casings. Everything i have purchased from them has always been consistent and shipped quickly.
Elana (verified owner) –
I love this product I make Orgonite Healing Crystal chambers and I could not be happier with the end result. Thank you
Glenda Emory (verified owner) –
This is the 5th 5 gallon bucket I’ve ordered over the last two years. Love the product and then quick shipping. Company is fantastic to deal with.
Dave (verified owner) –
I have been ordering this resin to make Orgone pyramids and generators and I am very satisfied. The price is the best I’ve found in my search for the most quality resin at the best price. The shipping is pricey but that’s not the fault of this company. I will continue to order this resin as long as the price remains the same. I like the tubs that it comes in- it has a nice pull-out pouring snout that gives a clean pour. Ordering is simple and fast and delivery is relatively quick. A great product at a great price.
Dave –
I continue to be happy with my orders of this resin. It’s a quality product. My only issue is the shipping is very expensive plus the $30 hazmat fee. It all makes me wonder if there is a cheaper local option. But I don’t believe there is. So I will continue purchasing from this online store and also taking advantage of the gracious 5% offer for writing a review.

Been ordering this resin for a couple years now and am very satisfied with the product and service!

I have been ordering this resin from illstreet for almost 5 years.
Great products!
Dave (verified owner) –
I continue to work with illstreet for resins for my business because their resins & process is excellent. Good customer service. The price on the shipping continues to creep up but that’s not the fault of the company. If they continue with their same prices, I will continue to be a customer.

I use this stuff for small casting that I then turn on a lathe. Has been perfect for my needs. It’s important to make sure that the temperature is not cold when curing (above 65 degrees). I did a couple casting when my garage temp. was in the 40’s. It still hardened fine, but the surface was very sticky. Takes some time to work the bubbles out. I usually tap my mold (a routed out 2X4) on a solid surface for a couple minutes to work bubbles toward the surface and then use a straightened paper clip to work the bubbles to the edges. I’m not too concerned about bubbles at the outer edges since I turn the casting down later, but most bubbles will disappear if I work them to the edge. As a liquid, there’s a very slight blue tint, but once it’s hardened, it’s crystal clear. I’m very satisfied with Silmar 41 and would recommend it
Mike (verified owner) –
I use this for casting and the product is great and the price is right. If you are looking for clear resin in your results, this is one of the better products to use.
Caution: You should only use this in a fully ventilated room. I keep an exhaust fan running at all times.
Chris (verified owner) –
When the material is under 75F, it may be too thick for all the bubbles to escape.
Anan (verified owner) –
Here from Canada!!
A good resin at an affordable price. Casting some pen blanks with reptile skin & feathers. All turned well. Use a home made vacuum chamber to get rid of the bubbles. Worked out fine.
But, but the shipping cost to Canada!! very high.
When the carrier brought it in at the door there was an additional $30.00, custom fees.
A gallon cost me $70. Still a very good deal.
Mindi (verified owner) –
Silmar 41 is great! As good as Castin’ Craft Clear Polyester Resin, at less than half the price (i think the gallon costs about $80 on Amazon). I use it for all kinds of art projects, from larger sized pyramids and garden mushrooms to small jewelry. I agree with the other review in that temperature is important, too cold and it takes awhile to set up, too warm and it sets too quickly (I usually do layered projects, so this is a big factor). Adjusting the amount of catalyst can help compensate when the temperature isn’t ideal (I have found around 70 degrees F is best). I haven’t had too much trouble with bubbles, seems they tend to work themselves out, I use a toothpick if they need a little coaxing. It’s easiest to mix resin and catalyst mindfully and deliberately so as to not get lots of bubbles to start with.
Working with resin has a learning curve but experience and experimentation can yield incredible results. : )

Marshall (verified owner) –
This product is great, very easy to work with. Extremely Great Price!
My only issue is on my previous order I received 8 cans, 2 which had some black debris in it. When I sent a photo and contacted customer service never heard back. Wasn’t a huge issue because we color most of our acrylic, but couldn’t use anything transparent on half of two gallons of it.
Hoping they get a barrel option soon. Cause we will be using more and more as time goes on.
Thank you for such an awesome product!

I have had not the first problem with my orders (Silmar 41). I have ordered from other companies in the past and a lot times I would find bugs and dirt or get old batch of Silmar 41. With illstreet Composites no bugs or dirt. I make game calls and they turn out great. Shipping is fast. I know I live here in South Carolina with them but I have ordered on a Wednesday and received my order on Thursday! Can`t beat that…………

Great product. Excellent resin at a fair price.
Anthony Sturtz (verified owner) –
I only use a small amount of this product at a time. I have tried other similar products and found this extremely easy to use and the end results are much better than the other products. I originally had some questions to make sure I was choosing the correct product and they got back to me in a reasonable amount of time and made sure I purchased the surfacing wax to go with the product to ensure the results I am looking for. I couldn’t be happier with the company and the products. I am going to continue using this product and placing my next order soon.

terry butler (verified owner) –
worked well I recieved it in a timely manner
Andrew Westergren (verified owner) –
Works very well. Have bought four gallons so far with no problems. Would have been nice to have mixing instructions come with it. Had to search the net for mixing amounts and cure times. Takes about a week to ship to CA. I will be buying more.
RESPONSE: Thanks for the feedback. People use the material for so many different applications we include a "mix at 1% MEKP" instruction on the label and a lot more detail on the website in the facebook comments. Maybe we will compile some of the comments and send out a leaflet with it in the future. Thanks again.
Micah Bartlett (verified owner) –
Have been using this for about 3 or 4 years now. The best resin I’ve been able to find online at the best price. Usually pretty fast processing time/shipping time. I have bought atleast 12 gallons a year. I love it when they come with the plastic lid. However I have had one malfunction when opening and had the whole lid (and screw part) come off. Other than that one malfunction (which is bound to happen after buying so much so often) It’s defiantly a great product.
Gordon Shadoan (verified owner) –
I received my 2 gallon order last week and we have completed several of our organite pyramids. It works great, very clear, allowing us to see all of the crystals, metals, etc. within. The only issue we have encounter is trying to pour a small amount (2 oz.) from the one gallon can into a small cup without spilling. Delivery took over a week coming from east coast to west coast. Will have to order more next time. Very satisfied with product.
the.orgonaut (verified owner) –
great product great price! Orgonite turns out nice and clear. Less brittle than castincraft.
Darrell Cox (verified owner) –
Silmar 41, easily the best casting resin I have used and at the best price! Always crystal clear castings. Prompt processing and shipment with each order. Thanks
Linda Miller (verified owner) –
My project is a large patio flat stone that I painted Koi fish, I want to pour the resin in layers, painting the fish repeatedly on each layer. I molded poly clay around the stone. Question: will the resin stick to the poly clay?Also, will resin stick to plastic wrap?
Response; If you use a little polyease, it won’t stick to anything that is sprayed with the release.
Miss Martha –
Excellent resin for my craft projects, works very well, will re order more soon.
Sin City Displays –
Great. Purchased many times and no problems. Resin is clear as I’ve found.

Resin is great for molded turning blanks. Louisiana climate is sometimes a problem, but we try to use on warm dry days. Adding color pigment makes the options endless. Glad we found this.

Silmar 41 is excellent resin. Creates a water clear cast if used without colorant. Its durable as long as you don’t over catalyze excessively. Consistent quality throught batches, I’ve been using with great results since 2014. Price on illstreet is the best on line.
Jamie (verified owner) –
I consider myself kind of crafty , and I bought this resin to make some beads and other small charms for necklaces that I sell locally. I called into illstreet and spoke with Chris. He was helpful and told me exactly what I needed then called back to check up on me to make sure everything had arrived and I knew exactly how to use the resin. I will be recommending this company to my friends and will be back myself in the future as well. Thanks Chris.
Charlene (verified owner) –
I use a LOT of resin for my crafts and run 3 online stores. there has been much trial and error to find the right resin to work with and I have gone through a few. I have used Castin Craft for a long time now and love how clear my product comes out, however, 32 dollars for 32 ounces gets expensive. So I found Silmar 41 and ordered to try. I did a compare and contrast and the ONLY difference was the cost was less than half of what I pay, and I get the SAME clear, beautiful quality, little to no bubbles with stirred and poured right. Take my word for it, as I am very picky with my quality, that this resin WILL NOT let you down, as long as you know how to use resin properly, you cannot go wrong. I am in the process of ordering 5 gallons and I will say with no doubt that this is the best investment I have made for my business and will save me 400+ dollars a month on average! THANK YOU FOR YOUR PRODUCT!!! I am forever your customer.
Tim Leiter (verified owner) –
I found your site by searching for polyester resins and your store came up after the search. I have read on some of the wood turning and pen making sites that Silmar 41 is a good brand of poly-resin. Your prices and shipping charges for the product are better than if I buy the poly-resin locally so I though I would try a purchase from you on the Silmar 41. I was very satisfied with the shipping time and quality of the resin. I make hand turned/made pens and pencils out of exotic and domestic woods and polyester resin. Your product worked very well. I have not used much of it because of health reasons but I will be using your Silmar 41 for all my pen blank casting needs and will buy from you when my need arises. I have already recommended your company and product on some of the forums I frequent because I am so satisfied with the quality and price.
Ron (verified owner) –
My first time using resin. It went well and I learned alot for my next project. Silmar 41 and the pigment worked as advertised. What I was most pleased with was the customer service. All my questions were answered quickly and in enough detail that I was able to complete my project without too many flaws. Thanks for all the help.
