Description

1,3-Butadiene, Ethenylbenzene, Methyl 2-Methyl-2-Propenoate, 2-Propenoic Acid Polymer is a high-performance, multi-component synthetic resin. This versatile polymer is engineered to deliver a unique balance of properties derived from its constituent monomers, making it a critical material for demanding industrial applications. It is primarily sought after by manufacturers in the coatings, adhesives, and specialty plastics sectors for its excellent film-forming characteristics, adhesion, and durability.

Application

• Industrial and Protective Coatings: Used as a key binder in high-performance paints, metal primers, and corrosion-resistant finishes for automotive and marine applications.
• Adhesives and Sealants: Serves as a primary resin in pressure-sensitive adhesives (PSAs), construction sealants, and industrial bonding agents requiring strong tack and cohesion.
• Plastic Modifiers and Impact Improvers: Incorporated into engineering plastics and PVC formulations to enhance impact resistance, flexibility, and processability.
• Textile and Fiber Treatment: Applied as a coating or sizing agent to improve the durability, water resistance, and handle of technical textiles and non-wovens.
• Paper and Packaging Coatings: Utilized to create barrier coatings and functional overlays that provide gloss, scuff resistance, and moisture protection.
• Caulks and Putties: Acts as a flexible, durable base in automotive and industrial caulking compounds.

Quality Control

Our polymer products are manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure consistent performance, including measurement of solid content, viscosity, pH, and glass transition temperature (Tg). Certificates of Analysis (COA) documenting these parameters are available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at temperatures between 15°C and 25°C (59°F and 77°F). Avoid freezing and prolonged exposure to extreme heat. Keep away from strong oxidizing agents.
