Introduction of industry
Phenolic resin can be applied in copper-clad laminates industry, especially in FR4, FR5 and CEM-1. The major purpose of phenolic resin is the hardener for epoxy resins. The resins can improve the properties of Tg point, thermal stability, coefficient of thermal expansion, and low water-solubility for CCL. KBC products can be classified into liquid and solid type, and widely applied in halogen free and lead free process procedure.

Application: copper-clad laminates, FR4, FR5, CEM-1, BPA Novolac, halogen free, lead free.
