Description

2-Propenoic Acid, 2-Methyl-, Methyl Ester, Polymer With Butyl 2-Propenoate, Ethenylbenzene, 2-Hydroxypropyl 2-Propenoate And 2-Methylpropyl 2-Propenoate CAS NO 125302-18-3 is a specialized acrylic copolymer designed to deliver a balanced profile of performance characteristics. This multi-monomer polymer is engineered to provide excellent adhesion, durability, and film-forming properties for demanding industrial applications. It is a critical raw material for formulators in the coatings, adhesives, and sealants industries seeking to enhance product performance and reliability.

Application

• Industrial and Protective Coatings: Used as a key binder in metal primers, machinery enamels, and corrosion-resistant topcoats, offering excellent substrate adhesion and weatherability.
• Adhesives and Sealants: Serves as a primary polymer in pressure-sensitive adhesives (PSAs), construction sealants, and assembly adhesives, providing strong bonding and flexibility.
• Automotive Refinish and OEM Coatings: Formulated into basecoats and clearcoats to achieve high gloss, color retention, and resistance to chemicals and environmental etching.
• Plastic and Wood Coatings: Enhances the finish and protective qualities of coatings for plastic substrates, furniture, and cabinetry.
• Inks and Overprint Varnishes: Imparts scratch resistance, gloss, and rapid drying properties in graphic arts and packaging applications.
• Textile and Leather Finishes: Used in coatings and binders to provide durable, flexible, and water-resistant finishes.

Quality Control

Our acrylic copolymer is manufactured under a stringent quality management system. Each batch undergoes rigorous testing for critical parameters including solids content, viscosity, acid value, glass transition temperature (Tg), and molecular weight distribution to ensure consistent performance and batch-to-batch uniformity. Certificates of Analysis (COA) detailing these specifications are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C/59-77°F). Keep away from heat sources and open flame. For long-term storage, ensure containers are sealed to prevent skin formation or changes in viscosity due to moisture or solvent loss.
