Polyester Resins

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. Click Here To View Our Catalyst Mixing Information(.pdf format).
Shelf Life: When purchasing our resins we guarantee their performance for 3 months after your purchase if stored at room temperature with their lids sealed. These resins can last longer than our 3 month guarantee, but we recommended testing a small cup of the resin before using it on an important project. Also, if the resins sit for over a month, we recommended shaking the sealed can or stirring the contents to ensure all solids are properly distributed.
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 by Ground with no extra fees with a maximum of one gallon per box.
5 Gallon pails can be shipped by UPS Ground only and require an additional $26.00 Hazardous Fee(charged by UPS).
Orders for multiple 5 GAL pails can be shipped by a common carrier(freight line) but require delivery to a commercial location.

404 Tooling Polyester Resin-Isophthalic
404 is an isophthalic polyester resin that is used where strength and durability is a must. Experiences lower shrinkage and a higher heat distortion temperature than orthophthalic type polyester resins. Used extensively in boat hulls and in fiberglass mold construction.

Polyester Gelcoats

Notes For Gelcoat Application
When Spraying:
We recommend thinning the gelcoat at about 10% by volume with
STYRENE(see link to purchase). This will allow better flow through your gun and better atomization.

When Brushing or Rolling: Adding about 5% to 10% Styrene will help the gelcoat flow out better and reduce brush/roll marks. Remember when brushing gelcoat, un-even thicknesses can cause wrinkling to occur. Tooling gelcoats especially require even thicknesses when applying. Please test your brushing method with these gelcoats before starting on an important project.

Pure White Gelcoat
Our standard pure white gelcoat is designed for exterior use in virtually all types of marine, automotive and general part construction and repair.
No wax added.
Pigment can be added to change the color of the gelcoat but any color added will be offset by the pure white color.

Please note: Our Surfacing wax (sanding aid) is required for your finish coat in order to sand/polish this product.

Note about choosing tooling gelcoat color:
Most of the time you want to choose the color based upon the surface you are applying the gelcoat onto when making your mold. The more contrast between the two, the better you will gauge the thickness and coverage of the gelcoat. As an example: If you are making a mold off something black you will want Orange Tooling Gelcoat. If you are making a mold off something red, you would likely want the Black Tooling Gelcoat.

Also, you should be prepared for the color of gelcoat you will be making your parts with inside the new mold. More contrast in the color will allow better visibility and ability to gauge coverage.
