GYC-EH-2 Hardener for Epoxy
GYC-EH-2 is an epoxy hardener with a fully environmentally friendly chlorine-free process. It can be added to electronic substrates where high demands of halogen-free and lead-free is required. It is mainly used for high temperature resistant products (FR4, FR5), Composite Epoxy Material (CEM-1) and Copper Clad Laminate (CCL). Besides that, GYC-EH-2 features excellent thermal stability in Tin furnace and meets the high Glass Transition Temperature (Tg) requirements. GYC-EH-2 has the characteristics of high temperature resistance, excellent bonding strength, and chemical and corrosion resistance.
