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

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.

This is a great product. It dry’s crystal clear. I have been making tile for my kitchen back splash. It’s very beautiful. I add color and glitter or whatever it works every time. The people working there are very helpful, and ship the resin out very fast.
