Fuji Kasei FXR-1020 Latent Epoxy Curing Agent Curing Temperature Lowering Additive

Product introduction
Fujicure FXR-1020 is a latent hardener for epoxy resins and is also a hardening accelerator; FXR-1020 contains active hydrogen molecules as hardening-promoting functional groups, which are easily dispersed in epoxy resins, and can be mixed with a mixture at room temperature. Can exhibit long-term storage stability. FXR-1020 can harden at lower temperatures with moderate heating.
When FXR-1020 is added with other latent hardeners such as dicyandiamide, only a small amount can reduce the temperature of the hardening cycle without affecting its original storage stability.
The hardened product of FXR-1020 can show lightness, good adhesion and excellent mechanical properties, so it can be used in a wide range of fields, such as adhesives, encapsulation, injection molding and powder coatings.
