Luvitec VPC55 K65W Vinylpyrrolidone / vinylcaprolactam copolymer BASF Polyvinyl acetate emulsions & derivatives (PVAc…) ADHESIVE >> Hot-melt Luvitec VPC55 K65W Vinylpyrrolidone / vinylcaprolactam copolymer The moisture absorption of PVP can be reduced stepwise by the partial or complete replacement of VP by a less hydrophilic monomer, such as e.g. vinylcaprolactam. Both polyvinylcaprolactam (Luvitec VCap K43E) as well as the copolymer made from vinylpyrrolidone and vinylcaprolactam are good film formers. By comparison with PVP, the tackiness of the films is significantly reduced even at high relative humidity. reduced moisture absorption reduced tackiness Adhesives Glue sticks Exhibits high adhesiveness (initial tack), outstanding adhesion and bonding to paper. Hot-melt adhesives Good adhesion, especially to glass, metal, paper and plastic surfaces; particularly suited for the production of remoistenable or watersoluble adhesives. Skin adhesives Viscosity modifier, toxicological safeness, readiness of crosslinking and formation of hydrogels - important properties in the production of flexible, skin-adhesive pads which adhere well. Vinylpyrrolidone / vinylcaprolactam copolymer. Used in glue sticks, remoistenable and watersoluble hot-melt adhesives and flexible, skin-adhesive pads. Offers good film formation properties, reduced moisture absorption and reduced tackiness.
