CA 2339815

A non-chrome process for the pretreatment of substrate surfaces to simultaneously clean them and improve their bonding strength for organic coatings such as adhesives, protective primers, sealants, paints, composites and similar materials conventionally bonded to such substrates, including non-chromated or chromated curable organic resin protective coatings applied directly to bare aluminum substrates. The invention involves the use of novel wipe solvent compositions containing a major volume of an environmentally-safe volatile organic solvent which has a low composite vapor pressure or is otherwise exempt from federal, state or local regulations, and a minor volume of a polyfunctional coupling agent, preferably of the silane type.

L'invention concerne un procédé sans chrome de prétraitement de surfaces de substrat afin de les nettoyer et simultanément d'améliorer leur résistance d'adhésion pour des revêtements organiques tels que des adhésifs, des couches de fond protectrices, des agents d'étanchéité, des peintures, des composites et matériaux similaires liés de manière classique à ces substrats, comprenant des revêtements protecteurs en résine organique durcissable non chromés ou chromés appliqués directement à des substrats en aluminium nus. L'invention consiste en l'utilisation de nouvelles compositions de solvants d'essuyage contenant un grand volume d'un solvant organique volatil sans danger pour l'environnement, ayant une pression de vapeur composite basse, ou autrement non soumis aux régulations fédérales, d'état ou local, et un petit volume d'un agent de couplage polyfonctionnel, de préférence du type silane.
