Elantas Bectron® PK 4364 B is a specialized, blue, one-component resin system that cures into a robust polyurethane duroplastic with some flexibility. Additionally, this advanced system includes a liquid polyol matrix with dispersed solid encapsulated polyisocyanate. It also contains a carefully chosen pigment blend to ensure controlled rheology. When heated, the resin releases the encapsulated polyisocyanate, initiating a polyaddition reaction that results in a durable and resistant cured material.
Highlight Features
