Silane triol capped expoxy-amine adhesion promoter for adhesive-bonded metal substrates

A water-based oligomer adhesion promoter material that promotes adhesion of paste adhesives used for structural bonding of metal components. The water-based system provides a convenient, one-step ambient cure process that minimizes the use of hazardous solvents. Reinforced metal substrates using the...

Zusammenfassung:	A water-based oligomer adhesion promoter material that promotes adhesion of paste adhesives used for structural bonding of metal components. The water-based system provides a convenient, one-step ambient cure process that minimizes the use of hazardous solvents. Reinforced metal substrates using the adhesion promoter material in conjunction to an ambiently cured paste adhesive offer significant improvement in terms of fatigue resistance. When used in repairing metal substrates having fatigue cracks, the adhesion promoter in conjunction with an ambiently cured paste adhesive minimizes fatigue crack propagation, thereby increasing the usable life of the metal substrate in strength bearing applications.
