JEFFCO 3103
4:1 LAMINATING & TOOLING HARDENER
Back to
Hardener page
Product Description:
Modified polyamine hardener. Very low viscosity, 30-minute pot life and fast set times make this an excellent general purpose hardener. Fast wetting of fiberglass reinforcements. Easy to use 4:1 volumetric mix ratio (100:22 by weight). May also be used with JEFFCO 908SC as a face-coat hardener (100:17 PHR by weight). High HDT, improving with post cure. Very tough when used with 1307LV or 1314 resins. Low viscosity allows use with thicker resins while still maintaining good wet-out. Low odor system. No VOC’s, 100% solids. Ships DOT non-regulated.
Product Uses:
Hand lay-up laminating, marine construction, tooling, epoxy face-coats, kit aircraft, RTM, epoxy injection or infusion, vacuum bagging, filament winding and chemically resistant coatings.
