Title:
ONE-PART SOLVENT-BASED ADHESIVE FOR BONDING POLYMER MATERIALS
Document Type and Number:
WIPO Patent Application WO2004078867
Kind Code:
A3
Abstract:
What is disclosed are adhesives and bonding methods employing a single coat of a solvent-based adhesive that effectively bonds thermoplastic polymers and especially thermoplastic elastomers. The adhesive components are a organosilane component selected from organosilane-isocyanate adduct and isocyanato-organosilane, a post-chlorinated polymer containing propylene repeating units or derivative thereof, and solvent. Also disclosed are methods for joining a rigid, structural substrate to a molten polymer such as a TPE via injection molding or extrusion. Durable adhesion between the adhesive treated portion of the rigid substrate and the melt-processed polymer is achieved with or without a previous heat treatment on the adhesive-coated substrate prior to joining to the thermoplastic melt.
