Description

Vinyl Chloride/Vinyl Acetate/Hydroxylpropyl Acrylate Terpolymer is a specialized synthetic resin engineered to deliver a unique balance of properties for advanced coating and adhesive formulations. This terpolymer is valued for its ability to provide excellent adhesion to diverse substrates, combined with enhanced flexibility, chemical resistance, and weatherability. It is a critical raw material for manufacturers in the paints & coatings, industrial adhesives, inks, and textile finishing industries seeking to develop high-performance, durable products.

Application

• High-Performance Industrial Coatings: Used as a film-forming agent in metal primers, can coatings, and coil coatings for corrosion resistance and adhesion.
• Adhesives and Sealants: Serves as a key binder in solvent-based and plastisol adhesives for automotive, construction, and packaging applications.
• Printing Inks: Imparts gloss, rub resistance, and substrate adhesion in flexographic and gravure inks for films and foils.
• Textile and Leather Finishes: Applied as a coating to provide water repellency, abrasion resistance, and a soft hand feel.
• Paper Coatings: Enhances the surface strength, printability, and gloss of specialty papers and paperboard.
• Vinyl Modification: Acts as a processing aid and property modifier in flexible PVC compounds.
