Description

Methyl 2-Methyl-2-Propenoate Polymer With Ethenyl Acetate, Ethyl 2-Propenoate And 2-Propenoic Acid is a specialized multi-component acrylic copolymer designed to deliver a balanced profile of film-forming, adhesive, and protective properties. This engineered polymer is valued for its ability to provide durable, clear films with excellent adhesion to diverse substrates and resistance to environmental factors. It serves as a critical raw material for formulators in the coatings, adhesives, and construction chemical industries seeking to enhance product performance and durability.

Application

• Industrial and Architectural Coatings: Used as a film-forming agent and binder in water-based paints, primers, and clear coats, offering good weatherability, gloss, and adhesion to metals, plastics, and masonry.
• Pressure-Sensitive Adhesives (PSAs): Functions as a key component in adhesive formulations for labels, tapes, and graphic films, providing a balance of tack, peel strength, and cohesion.
• Construction Chemicals: Incorporated into tile adhesives, grouts, and cementitious waterproofing membranes to improve flexibility, bond strength, and water resistance.
• Textile and Leather Finishes: Acts as a coating or finishing agent to provide a protective layer, enhance handle, and improve the durability of fabrics and leather goods.
• Paper and Packaging Coatings: Applied as a barrier or functional coating to improve printability, gloss, and resistance to water and grease for paperboard and packaging materials.
• Sealants and Caulks: Utilized as a polymeric base to impart elasticity, adhesion, and longevity to sealants used in construction and automotive 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 characterized for critical parameters including solid content, viscosity, pH, glass transition temperature (Tg), and minimum film-forming temperature (MFFT). A comprehensive Certificate of Analysis (COA) detailing these specifications is provided with every 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 temperatures between 15°C and 25°C (59°F and 77°F). Do not freeze. Keep away from heat sources and open flame. For long-term storage, ensure containers are sealed to prevent skin formation or evaporation.
