Bisphenol-A Resole Resins in Preparation Aqueous Adhesives for Bonding Silicon Rubber-to-Metal

Abstract

An aqueous adhesives composition of bisphenol-A resoles resins as adhesion promoter, in combination with a silane compound were prepared useful for bonding silicon rubber to metal surfaces. Silicon rubber-metal joints were prepared and tested according to ASTM D 429 before and after the unloaded specimens were kept in boiling water to find their mechanical properties. All results showed good adhesion to metal surfaces and the rupture was in silicon rubber body.
