GYC-EH-2 Hardener for Epoxy

Description

Intro

GO YEN CHEMICAL INDUSTRIAL CO., LTD. (GYC GROUP) is a leading manufacturer of specialty chemicals in Asia. We devote ourselves to supplying products and solutions to our customers worldwide to satisfy and expand the market needs.

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.

Operations

• Please add appropriate solvents and stir it until the mixture is completely dissolved.
• Filter the mixture by using 25µ and 5µ two-stage filter before using it.
• An improved physical property is needed, add hydroxyl with appropriate dose which is 1.1-1.15 times as much as the dose of epoxy.

GYC technical department recommends that the dose should be adjusted in accordance with different epoxy hardeners development demands.
