Vinnolit® SA 1062/7 Vinyl Chloride/Vinyl Acetate Copolymer Extender resin
Categories: Polymer; Thermoplastic; Vinyl (PVC); Polyvinyl Chloride - Polyvinyl Acetate Copolymer

Material Notes: Vinnolit® SA 1062/7 Vinyl chloride/vinyl acetate copolymer extender resin for paste application. Vinnolit® 1062/7 is a copolymeric extender resin 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® SA 1062/7 processing can be improved as the viscosity is considerable reduced, particularly in low plasticizer content and highly filled plastisols. By exchanging part of a copolymer paste resin the storage stability, dilatancy and deaeratibility are improved. In addition, the vinyl acetate content enables to lower gelling temperatures. Adhesion to various substrates, such as metal and synthetic fibers is improved. Vinnolit® SA 1062/7 is suited for automotive underbody sealants, carpet backing and laminating pastes. Vinnolit® SA 1062/7 can be processed by all the standard methods, such as coating, dipping, casting and spraying. Vinnolit® SA 1062/7 is especially used in automotive underbody coatings and sealants.
