Compositions based on silane-terminated polymers with improved adhesion on thermoplastics
An adhesive composition, including at least polymer containing silane groups, between 15 and 35 wt.-% of at least one polymeric plasiticzer, between 0.5 and 2.5 wt.-% of at least one monomeric or oligomeric aminofunctional alkoxysilane S1 with a nitrogen content of between 4.5 and 14.5 wt.-%, and between 0.5 and 2.5 wt.-% of at least one oligomeric aminofunctional alkoxysilane S2 with a nitrogen content of between 15 and 20 wt.-%. The adhesive composition is particularly suitable to seal or bond thermoplastic substrates, such as polyolefins or bituminous materials, and shows fast adhesion build-up and low volatile organic carbon (VOC).
Method of Bonding Perfluoroelastomeric Materials to a Surface
The invention includes a method of bonding a perfluoroelastomer material to first surface that includes: (a) contacting a first surface with a bonding agent comprising a curable perfluoropolymer and a curing agent; (b) curing the bonding agent to form a perfluoroelastomer material that is bonded to the first surface. In the practice of such method, the bonding agent may be a solution prepared by dissolving the curable perfluoroelastomer and the curing agent in a solvent. In an embodiment of the invention, the perfluoroelastomer material formed in step (b) is a coating layer or, alternatively, the first surface is a surface of a perfluoroelastomer member and the perfluoroelastomer material formed is a perfluoroelastomer weld.
