Phenolic Resin FRJ551 is a thermosetting alkyl phenolic resin primarily used in the synthesis of chloroprene rubber adhesives. Within chloroprene rubber adhesives, FRJ551 enables the adhesive to achieve low initial viscosity and excellent viscosity stability, while demonstrating strong bonding strength at room temperature. Experience FRJ551—like spring rain, it infuses neoprene rubber adhesives with vitality. Its low initial viscosity and outstanding viscosity stability enable adhesives to deliver robust bonding strength even at room temperature. Infuse your product projects with spring-like vigor—achieve stronger bonds and elevate your projects to excellence!
