Nature of Adhesion through Silane Coupling Agents

  • Edwin P. Plueddemann

Abstract

Most thermosetting polymers undergo some shrinkage during cure. This may range from 6 to 10% for polyesters to 3 to 4% for epoxies. Such shrinkage in the presence of fillers or reinforcements sets up stresses at the polymer-resin interface. Bush1 embedded strain gauge transducers in a polyester resin cured at 120°C and measured internal static pressures of 14 to 21 MPa (2000–3000 psi). Bulk mold shrinkage may be reduced to less than 1% by loading the polymer with particulate fillers, but interfacial stresses are merely transferred to the filler surfaces.
