Description

2-Propenoic Acid, 2-Methyl-, Polymer With Butyl 2-Propenoate, Ethenylbenzene, Methyl 2-Methyl-2-Propenoate And 1,2-Propanediol Mono-2-Propenoate is a high-performance, multi-component acrylic copolymer designed to deliver exceptional film-forming properties, adhesion, and durability. This versatile polymer is engineered to meet the stringent demands of advanced coating and adhesive formulations, providing a critical balance of flexibility, chemical resistance, and weatherability. It is an essential raw material for manufacturers in the industrial coatings, pressure-sensitive adhesives, and specialty sealants sectors seeking to enhance product performance and reliability.

Application

• Industrial and Protective Coatings: Used as a primary binder in metal primers, topcoats, and anti-corrosive paints for automotive, machinery, and structural steel.
• Pressure-Sensitive Adhesives (PSAs): Serves as a key component in the formulation of tapes, labels, and graphic films, offering excellent tack and peel strength.
• Architectural Coatings: Enhances the durability, scrub resistance, and adhesion of exterior and interior wall paints and elastomeric coatings.
• Plastic and Wood Coatings: Provides superior adhesion to difficult substrates and improves the finish and protective qualities of coatings for furniture and consumer goods.
• Specialty Sealants and Caulks: Imparts flexibility, adhesion, and long-term stability to construction and automotive sealant formulations.
• Printing Inks: Utilized in overprint varnishes and ink vehicles to improve gloss, rub resistance, and substrate adhesion.

Quality Control

Our production of this acrylic copolymer adheres to strict quality management systems to ensure batch-to-batch consistency and performance reliability. Quality is verified through a comprehensive suite of tests including viscosity, solids content, acid value, glass transition temperature (Tg), and mechanical property assessments. Certificates of Analysis (COA) detailing all relevant specifications are provided with every shipment 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 exposure to extreme heat or freezing conditions to prevent changes in viscosity or polymer stability. Keep away from strong oxidizing agents.
