Description

Vinyl Chloride/Vinyl Acetate/Maleic Acid Terpolymer is a synthetic, multi-functional polymer engineered for superior adhesion, film-forming, and chemical resistance. This terpolymer is valued for its ability to modify the properties of base resins, enhancing flexibility, adhesion to difficult substrates, and durability. It is a critical raw material for formulators and manufacturers in the coatings, adhesives, and specialty plastics industries seeking to improve product performance.

Application

• Adhesive Formulations: Used as a key tackifier and adhesion promoter in pressure-sensitive adhesives (PSAs), hot-melt adhesives, and industrial bonding agents.
• Industrial & Protective Coatings: Serves as a film-forming agent and modifier in metal primers, can coatings, and corrosion-resistant paints to enhance adhesion and chemical resistance.
• Printing Inks: Incorporated into flexographic and gravure inks to improve pigment wetting, gloss, and adhesion to non-porous films and foils.
• Textile & Fiber Treatment: Acts as a binder and coating agent for textiles, non-wovens, and fibers to impart stiffness, water resistance, or specific hand feel.
• Plastic Modification: Employed as a processing aid and impact modifier in PVC and other polymer blends to enhance flexibility and compatibility.
• Paper & Packaging Coatings: Used in coatings for paperboard and packaging to provide moisture barrier properties, heat sealability, and improved printability.

Quality Control

Our Vinyl Chloride/Vinyl Acetate/Maleic Acid Terpolymer is manufactured under a strict quality management system. Each batch undergoes rigorous testing for critical parameters including monomer ratio, acid value, viscosity, and solids content to ensure batch-to-batch consistency and performance reliability. Certificates of Analysis (COA) documenting full specifications are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Keep away from heat sources and open flame. For long-term storage, consider under an inert atmosphere to maintain polymer stability.
