Description

2-Propenoic Acid, 2-Methyl-, Butyl Ester, Polymer With Ethenylbenzene, 2-Ethylhexyl 2-Methyl-2-Propenoate, 1,2-Propanediol Mono-2-Propenoate And 2-Propenoic Acid is a specialized acrylic copolymer designed to deliver a unique balance of properties for demanding industrial formulations. This multi-monomer polymer is engineered to provide excellent adhesion, flexibility, and chemical resistance, making it a critical component in high-performance coatings and adhesives. It is essential for manufacturers in the paints & coatings, pressure-sensitive adhesives, and industrial sealants sectors seeking to enhance product durability and performance.

Application

• High-Performance Industrial Coatings: Used as a key resin in metal, plastic, and wood coatings requiring superior weatherability and chemical resistance.
• Pressure-Sensitive Adhesives (PSAs): Provides excellent tack, peel strength, and holding power for labels, tapes, and graphic films.
• Architectural Paints: Imparts durability, scrub resistance, and low-temperature film formation to exterior and interior paints.
• Automotive Refinish & OEM Coatings: Contributes to the chip resistance, gloss, and flexibility of automotive paint systems.
• Industrial Sealants and Caulks: Enhances adhesion to diverse substrates and provides long-term elasticity and durability.
• Printing Inks: Used in overprint varnishes and ink formulations to improve gloss, rub resistance, and adhesion.
• Textile and Leather Finishes: Acts as a binder or coating to provide water resistance, soft hand feel, and durability.
• Specialty Binders: Serves as a versatile polymeric binder in non-woven fabrics, construction materials, and composite applications.

Quality Control

Our production of this acrylic copolymer adheres to strict quality management systems to ensure batch-to-batch consistency and performance reliability. Each lot is tested against comprehensive in-house specifications covering parameters such as solids content, viscosity, pH, glass transition temperature (Tg), and monomer residue levels. A Certificate of Analysis (COA) detailing these results is provided with every shipment. We support compliance with global regulatory frameworks including REACH.

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). Keep away from heat sources and open flame. Ensure containers are kept tightly sealed when not in use to prevent skinning or changes in viscosity.
