A method for modifying the surface of an architectural finish for a metal structure that increases its surface energy to almost double the surface energy obtained by the methods currently being performed, particularly in the curtain wall industry. Specifically, a flame plasma treatment process is applied to the surface of the finish in accordance with the disclosed principles to achieve the disclosed results.

Contact adhesive compositions comprising polychloroprene and, based on the polychloroprene content, 10 to 99 wt % of ethylene-vinyl acetate copolymer exhibit outstanding adhesion to substrates such as ethylene-vinyl acetate copolymers, thermoplastic elastomers or flexible PVC. The contact adhesive compositions of the invention are especially suitable for use in the bonding of articles, preferably articles in which at least part of the articles to be bonded consists of polyurethane, flexible PVC, ethylene-vinyl acetate copolymers and/or thermoplastic elastomers. This allows the adhesive composition to be employed widely in the footwear industry, for the bonding of roofing membranes containing flexible PVC, ethylene-propylene-diene rubber (EPDM) and/or ethylene-vinyl acetate copolymers, or for the bonding of synthetic leather based on flexible PVC.

A method for nano-depth surface activation of a PTFE-based membrane and relates to the technical field of polymer composites is disclosed. The method comprises the following steps: covering a functional surface of a PTFE-based nano functional composite membrane, performing surface activation treatment on a single surface of the membrane to which a bonding adhesive is applied, and migrating and complexing a high-toughness cold bonding adhesive tape on the membrane surface, with an activated structure layer, of the PTFE-based nano functional composite membrane through a mechanical adhesive applying device to form an adhesive-membrane complex. An extremely strong affinity and a high-strength bonding performance are generated between the membrane and the adhesive, and the adhesive-membrane complex is formed. Integration of membrane/adhesive bonding complexing, membrane/membrane bonding complexing and membrane/adhesive layer bonding is realized.

The intense purple dye normally found in purple primers for use in the adhesive bonding of plastics is replaced with a leuco dye capable developing a visually intense color when activated through contact with the particular plastic being bonded or a complementary solvent cement.
