Activated Gas Plasma Surface Treatment of Newer Structural Plastics for Adhesive Bonding.
Abstract
A limited investigation was conducted on adhesive bonding of eight of the newer structural plastics. The plastics were: Valox, an aromatic polyester; PES 200P, a polyethersulfone; Astrel, a polyarylsulfone; Ryton, a polyphenlene sulfide; Halar, an E-CTFE fluoropolymer, and three different polyamides, nylons 11, 6/12, and 12. Activated gas plasma (helium and oxygen) treatment was used in treating the plastics. Significant improvements in shear strength values over previous treatments (sanding, etching, flame treating, solvent wiping) were obtained for Valox, Astrel, Ryton, Halar, and nylon 6/12. Only two plastics, Halar and Valox, bonded with EC-2214, a 121 C (250 deg) curing adhesive, showed significant increases in bond strength values after gas plasma treatment when compared to the room temperature curing Epon 828/Versamid 140 adhesive bonded specimens.
