Description

2-Propenoic Acid, 2-Methyl-, Butyl Ester, Polymer With Ethene, Methyl 2-Methyl-2-Propenoate And 1-Propene is a specialized acrylic copolymer designed to deliver a unique balance of properties for high-performance industrial applications. This multi-monomer polymer offers exceptional versatility, providing tailored characteristics such as film formation, adhesion, and chemical resistance. It is a critical raw material for formulators in the coatings, adhesives, and sealants industries seeking to enhance product durability and performance.

Application

• Industrial and Protective Coatings: Used as a key binder in solvent-based and high-solids coatings for metal, plastic, and wood substrates, providing excellent weatherability and corrosion resistance.
• Adhesives and Sealants: Serves as a primary polymer component in pressure-sensitive adhesives (PSAs), construction sealants, and industrial bonding agents, offering strong adhesion and flexibility.
• Automotive Refinish and OEM Coatings: Formulated into primers, basecoats, and clearcoats to achieve superior gloss retention, chip resistance, and environmental durability.
• Plastic and Leather Finishes: Applied as a topcoat or modifying resin to enhance the surface properties, appearance, and scratch resistance of synthetic materials.
• Inks and Overprint Varnishes: Utilized in specialty printing inks and protective varnishes to improve gloss, rub resistance, and drying characteristics.
• Textile and Fiber Treatment: Acts as a coating or sizing agent to impart water repellency, stiffness, or other functional properties to fabrics and non-wovens.

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 molecular weight distribution, monomer content, viscosity, and glass transition temperature (Tg). Certificates of Analysis (COA) documenting these specifications are provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Keep away from heat sources and open flame. For long-term storage, maintain under an inert atmosphere to prevent oxidation and skin formation.
