Vinnolit® C 12/62 V Vinyl chloride/vinyl acetate copolymer extender resin for paste application. Vinnolit® C 12/62 V is a copolymeric extender resin having a high vinyl acetate content which has been specially developed for paste making. In blends with paste-making PVC resins, it combines the good viscosity-reducing properties of the homopolymer paste extender resins with the lower gelling temperatures typical of vinyl acetate copolymers. By incorporating an extender resin such as Vinnolit® C 12/62 V processing can be improved as the viscosity is considerably reduced, particularly in low plasticizer content and highly filled plastisols. By exchanging part of a copolymer paste resin the shelf life and deaeratibility are improved and dilatancy is reduced. The higher vinyl acetate content of Vinnolit® C 12/62 V allows lower gelling temperatures. The adhesion to various substrates, such as metal and synthetic fibers is improved. Vinnolit® C 12/62 V is particularly well suited for automotive underbody coatings and sealants, carpet backing and laminating pastes. Like all extender resins Vinnolit® C 12/62 V can be processed by all the standard methods, such as coating, dipping, casting and spraying.Information provided by Vinnolit. |
