Description

2-Propenoic Acid, 2-Methyl-, Monoester With 1,2-Propanediol, Polymer With 1,3-Butadiene And 2-Propenenitrile is a specialized acrylic copolymer designed to deliver a unique balance of properties from its constituent monomers. This engineered polymer is critical for formulators seeking to enhance the performance characteristics of coatings, adhesives, and sealants. It is particularly valuable for industries requiring materials with excellent film formation, adhesion, and chemical resistance.

Application

• Industrial and Protective Coatings: Used as a key binder or modifier to improve durability, weatherability, and adhesion to various substrates like metals and plastics.
• Pressure-Sensitive Adhesives (PSAs): Imparts tack, peel strength, and cohesive balance for labels, tapes, and graphic films.
• Textile and Leather Finishes: Serves as a coating or binder to provide water resistance, flexibility, and a durable finish to fabrics and synthetic leather.
• Paper and Packaging Coatings: Enhances surface gloss, printability, and water resistance of paperboard and packaging materials.
• Sealants and Caulks: Contributes to elasticity, adhesion, and long-term performance in construction and automotive sealant formulations.
• Modifier for Plastics and Elastomers: Used as an impact modifier or processing aid to improve the toughness and flexibility of compounded materials.

Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards. Each batch is controlled against key parameters including solid content, viscosity, acid value, and glass transition temperature (Tg) to guarantee batch-to-batch consistency. Certificates of Analysis (COA) documenting these specifications are available upon request.

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 or skin formation.
