Description

Fatty Acids, Vegetable-Oil, Polymers With Acrylonitrile, Crotonic Acid, Me Methacrylate, Pentaerythritol, Phthalic Anhydride And Styrene CAS NO 68915-20-8 is a specialized polymeric resin designed for high-performance industrial applications. This complex copolymer offers a unique balance of properties derived from its multi-component structure, including flexibility, adhesion, and chemical resistance. It is a critical raw material for formulators in the coatings, adhesives, and specialty plastics industries seeking to enhance product durability and functionality.

Application

• Industrial Coatings Binder: Used as a film-forming agent in high-durability protective coatings for metal, wood, and concrete, providing excellent weather resistance and adhesion.
• Adhesive & Sealant Formulation: Serves as a key polymeric component in structural adhesives, pressure-sensitive adhesives (PSAs), and construction sealants, contributing to tack, cohesion, and bond strength.
• Printing Inks: Employed in the manufacture of specialty printing inks, including overprint varnishes and flexographic inks, where it improves gloss, rub resistance, and substrate wetting.
• Textile & Leather Finishing: Functions as a finishing resin to provide fabrics and leather with water repellency, softness, and improved handle.
• Plastic Modifier: Acts as an impact modifier or compatibilizer in polymer blends and composites to enhance toughness and processing characteristics.
• Corrosion Inhibitive Primers: Formulated into primers for automotive and marine applications, where its film integrity helps protect substrates from corrosive environments.

Quality Control

Our production of this polymeric resin adheres to strict batch-to-batch consistency protocols to ensure reliable performance in your formulations. Quality is monitored through key parameters including acid value, viscosity, solids content, and color. Certificates of Analysis (COA) documenting these specifications are available for every shipment upon request, providing full traceability and compliance data for your quality management systems.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at ambient temperatures (ideally 15-25°C). Keep away from heat sources and open flame. Under these conditions, the product is typically stable for 24 months from the date of manufacture. Always check the specific technical data sheet for the purchased grade.
