Union of a fluoropolymer.

A method of bonding a fluoropolymer to an organic substrate, comprising: providing a fluoropolymer having a surface providing an organic substrate having a surface, said organic substrate binding composition including an amino-substituted organosilane incorporated into it such that when the surfaces contact, the bonding composition is in contact with the fluoropolymer and the substrate simultaneously, and contacting the surfaces and heating the fluoropolymer and the substrate to a temperature for a sufficient time to bond the fluoroplastic and the substrate to form a bonded article.
