FORTEGRA® 401

FORTEGRA® 401 is a specialty polyoxypropylene diamine modified liquid epoxy resin. FORTEGRA® 401 is designed for the use of enhancing the toughness and flexibility for epoxy systems, mainly used in epoxy adhesives and coatings products. With improved toughness and flexibility, the adhesives products can achieve better drop resistance and impact peeling resistance, as well as perform well on aging tests. While for the applications in coatings, it brings the benefits of improved adhesion and impact resistance. A wide variety of curing agents are available to cure this resin at ambient conditions. Most frequently used curing agents are aliphatic polyamines, polyamides and modified versions of these. Elevated temperature cure is necessary and post-cure required to develop full end properties if anhydride or catalytic curing agents are employed.
