EP4119
Corrosion-Resistant Polyester Resin
GENERAL DESCRIPTION: EP4119 is a high performance resin which has
greater water, chemical and temperature resistance than EP4117. It is a room
temperature curing, rigid, translucent, isophthalic polyester resin for use
with fiberglass fabric. It is an
air-inhibited resin so additional layers can be applied without sanding between
layers. Successful applications include
water tanks, acid tanks, and process vessel linings or applications where
resistance to temperature or chemicals is important.
MIX RATIO: The gel time and cure time are
both dependent on three parameters: (1) the percentage of MEK-P catalyst used;
(2) the temperatures of all ingredients and the surrounding environment; (3)
the mass concentration of the resin, i.e., a solid-cast shape vs. thin
film. A good starting point, at 72°F, is 1-1/4 % catalyst
by weight. This is equivalent to 10 drops catalyst per ounce of resin, or 1
teaspoon catalyst per pint of resin. This level will result in a 15 min pot
life and a 24-hour cure. As temperatures rise above 72°F, decrease catalyst,
and vice-versa. Polyester resins will not cure below 60°F. Experiment until the
correct ratio is determined for your specific application. In general, mix what
you can use in 10 minutes. Apply a thin even coat approximately 1/16” over
entire surface. Remember to always wear eye-protection when working with
polyester resin and catalyst.

EP4119 matches, and in some cases exceeds, the performance the
performance of many high cost corrosion resistant polymers including vinyl
ester and bisphenol A polyesters. Yet
EP4119 is lower in cost than any of these other resins. This combination of low cost and high
performance is among the reasons why EP4119 is so widely used.
Warning: Uncured product may cause respiratory or skin
irritation with possible sensitization. Use only with adequate ventilation. If
skin contact occurs, wash thoroughly with soap and water. In case of eye
contact, flood with water and call a physician. Use of gloves and face shield
is recommended. This product should not
be used near food or where prolonged skin contact may occur.
