Description

2-Propenoic Acid, Butyl Ester, Polymer With 1,1-Dimethylethyl 2-Propenoate And Ethenylbenzene is a high-performance acrylic copolymer designed for demanding industrial applications. This terpolymer combines the properties of butyl acrylate, tert-butyl acrylate, and styrene to deliver a unique balance of durability, flexibility, and chemical resistance. It is essential for formulators seeking to enhance the performance characteristics of coatings, adhesives, and sealants. Key industries that rely on this polymer include automotive, construction, and specialty chemical manufacturing.

Application

• As a key film-forming agent and binder in industrial and architectural coatings for improved weatherability and adhesion.
• Formulation of high-performance pressure-sensitive adhesives (PSAs) and sealants requiring excellent tack and cohesion.
• Modifier for plastics and composite materials to enhance impact resistance and processing characteristics.
• Base polymer for textile and leather finishing chemicals, providing durable, flexible films.
• Component in printing inks to improve gloss, rub resistance, and substrate adhesion.
• Used in the production of specialty elastomers and impact modifiers for engineering polymers.

Quality Control

Our production of this acrylic terpolymer adheres to strict quality management systems to ensure batch-to-batch consistency and performance reliability. Every lot is characterized for critical parameters including molecular weight distribution, monomer content, glass transition temperature (Tg), and solution viscosity. Certificates of Analysis (COA) detailing these specifications are provided with each shipment. We support compliance with relevant 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 room temperature (15-25°C). Keep away from heat sources and open flame. For long-term storage, consider under an inert atmosphere to prevent oxidation. Keep container tightly sealed when not in use to maintain product integrity.
