Description

Butanoic acid, 3-oxo-, 2-(2-methyl-1-oxo-2-propenyl)oxyethyl ester, polymer with butyl 2-propenoate, ethenylbenzene, 2-hydroxyethyl 2-methyl-2-propenoate and methyl 2-methyl-2-propenoate is a specialized multi-component acrylic copolymer designed for high-performance applications. This polymer offers a unique balance of properties derived from its carefully selected monomer composition, including adhesion, flexibility, and chemical resistance. It is primarily utilized in the formulation of advanced industrial coatings, adhesives, and sealants where durable film formation and environmental stability are critical requirements.

Application

• Industrial and Protective Coatings: As a key resin component in coatings for metal, plastic, and wood substrates, providing excellent adhesion, gloss, and weatherability.
• High-Performance Adhesives: Used in pressure-sensitive adhesives (PSAs) and structural adhesive formulations, offering strong bonding and cohesion.
• Automotive Finishes: Employed in primer, basecoat, and clearcoat systems for automotive OEM and refinish applications.
• Plastic Coatings: Enhances surface properties of consumer electronics, appliances, and other plastic products.
• Industrial Maintenance Paints: Formulated into paints for bridges, pipelines, and industrial facilities requiring corrosion and chemical resistance.
• Printing Inks: Acts as a binder in specialty printing inks, contributing to film integrity and substrate adhesion.
• Sealants and Caulks: Provides flexibility and durability in construction and automotive sealant products.

Quality Control

Our production of this advanced acrylic copolymer adheres to strict quality management systems, ensuring batch-to-batch consistency for formulators. Key parameters such as solids content, viscosity, acid value, hydroxyl value, and glass transition temperature (Tg) are rigorously monitored. Certificates of Analysis (COA) detailing these specifications are provided with each 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). Avoid exposure to extreme heat, direct sunlight, and sources of ignition. Keep containers tightly sealed when not in use to prevent skinning or changes in viscosity.
