Resinlab® EP1390 Medium Viscosity, Self Extinguishing Flame Retardant Epoxy Casting Resin System

Resinlab™ EP1390 is a RoHS compliant, medium viscosity, self extinguishing flame retardant epoxy casting resin system. It is recognized under the Component Recognition Program of Underwriters Laboratories Inc., (File# E186034) for UL Standard 94. EP1390 qualifies for a vertical burn rating of V-0 at 3mm thickness. It gives very good resistance to water, salt spray, inorganic acids and bases and most organic solvents. It cures quickly at room temperature to a tough, semi-rigid polymer. It has good wetting and adhesion to most surfaces and is free flowing to penetrate voids and give good air release. EP1390 was formulated to a 4/1 volume mix ratio for ease of use in automatic mixing equipment with static mixers. It contains soft, low-abrasion fillers which can separate over time, although they have good resistance to hard settling. If used in side-by-side cartridge format, they should be stored horizontally in a cool place (5C), rotating stock on a FIFO basis. EP1390 will generally reach handle cure at room temperature within 1 to 4 hours depending upon mass and ambient temperature. Full cure usually achieved within 24 – 48 hours. Cure time can be accelerated by the application of heat after product has gelled. Times and temperatures from 2 hours at 60°C to 30 minutes at 100°C are typical for most castings (less than 100 grams).Information Provided by Resinlab L.L.C., an Ellsworth Adhesives Company.
