Description

Styrene-Dibutyl Fumarate-Hydroxyethyl Methacrylate Copolymer is a specialized multi-functional polymer designed to impart unique performance characteristics in advanced coating and adhesive formulations. This terpolymer matters for its ability to combine the hardness and gloss of styrene, the flexibility and adhesion of fumarate esters, and the cross-linking potential and hydrophilicity of hydroxyethyl methacrylate. Industrial manufacturers in the coatings, inks, and specialty adhesives sectors need this copolymer to develop high-performance products with tailored properties such as enhanced durability, chemical resistance, and improved substrate adhesion.

Application

• Industrial and Protective Coatings: Used as a key resin component to enhance film formation, weather resistance, and adhesion to metals and plastics.
• Printing Inks: Serves as a binder to improve gloss, rub resistance, and drying characteristics in solvent-based and UV-curable ink systems.
• Specialty Adhesives and Sealants: Imparts flexibility, tack, and cohesive strength in formulations requiring strong bonding to diverse surfaces.
• Automotive Finishes: Contributes to the durability, gloss retention, and chemical resistance of topcoat and primer formulations.
• Wood Coatings: Enhances the clarity, scratch resistance, and application properties of varnishes and lacquers.
• Plastic Coatings: Improves adhesion and surface compatibility for coatings applied to polyolefins and other engineered plastics.
• Textile and Leather Finishes: Used to create durable, flexible, and water-resistant surface treatments.

Quality Control

Our Styrene-Dibutyl Fumarate-Hydroxyethyl Methacrylate Copolymer is manufactured under a strict quality management system. Each batch undergoes rigorous testing for key parameters including monomer content, molecular weight distribution, viscosity, and appearance to ensure consistent performance and batch-to-batch reproducibility. Certificates of Analysis (COA) documenting all test results are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Keep away from heat sources and open flames. This material is light-sensitive; prolonged exposure to light should be avoided to maintain product integrity.
