Description

2-Propenoic Acid, 2-Methyl-, Butyl Ester, Polymer With Methyl 2-Methyl-2-Propenoate And Oxiranylmethyl 2-Methyl-2-Propenoate is a specialized acrylic copolymer designed to deliver a unique balance of flexibility, adhesion, and chemical resistance. This product is engineered to serve as a high-performance binder or film-forming agent in advanced coating and adhesive formulations. It is particularly valuable for industries requiring durable, cross-linkable polymer systems with excellent substrate wetting and weatherability.

Application

• Industrial and Protective Coatings: Used as a primary resin in metal, plastic, and wood coatings requiring enhanced durability, gloss, and resistance to chemicals and abrasion.
• Adhesives and Sealants: Functions as a key polymeric component in structural, pressure-sensitive, and laminating adhesives, providing strong bonding and flexibility.
• Automotive Finishes: Employed in primer, basecoat, and clearcoat formulations to improve chip resistance, appearance, and long-term exterior durability.
• Inks and Overprint Varnishes: Acts as a vehicle in graphic arts and packaging inks, offering good pigment wetting, adhesion to various substrates, and rub resistance.
• Textile and Leather Finishes: Utilized in coatings for fabrics and leather to impart water repellency, soft hand feel, and improved mechanical properties.
• Cross-Linking Polymer Systems: The oxiranylmethyl (glycidyl) groups present in the polymer chain enable thermal or catalytic cross-linking for high-performance thermoset applications.

Quality Control

Our production of this acrylic terpolymer adheres to strict quality management systems to ensure batch-to-batch consistency and performance reliability. Key parameters such as monomer content, epoxy value, molecular weight distribution, and viscosity are rigorously monitored. A comprehensive Certificate of Analysis (COA) detailing specific lot specifications is 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, and well-ventilated area at room temperature (15-25°C). Keep away from heat sources and open flame. Under recommended storage conditions, the product is typically stable. Prolonged exposure to elevated temperatures should be avoided to prevent premature polymerization or changes in viscosity.
