Description

2-Propenoic Acid, 2-Methyl-, Polymer With Butyl 2-Methyl-2-Propenoate And Methyl 2-Methyl-2-Propenoate is a high-performance, multi-component acrylic copolymer designed for demanding industrial applications. This terpolymer offers a unique balance of properties derived from its constituent monomers, making it a versatile material for formulating advanced coatings, adhesives, and sealants. It is particularly valuable for industries requiring durable, weather-resistant, and chemically stable polymer matrices.

Application

• Industrial and Protective Coatings: Used as a key binder in solvent-based or high-solid coatings for metal, wood, and plastic substrates, providing excellent adhesion, gloss, and resistance to weathering and chemicals.
• Pressure-Sensitive Adhesives (PSAs): Serves as a primary component in tape and label adhesives, offering a tunable balance of tack, peel strength, and shear resistance.
• Automotive Refinish and OEM Coatings: Formulated into primers, basecoats, and clearcoats to deliver high durability, color retention, and resistance to environmental degradation.
• Industrial Adhesives and Sealants: Provides strong bonding and sealing properties in construction, assembly, and maintenance applications.
• Printing Inks: Used in formulations for overprint varnishes and specialty inks to enhance rub resistance, gloss, and drying properties.
• Plastic Modifiers and Impact Improvers: Can be incorporated into other polymer systems to modify toughness, flexibility, and processing characteristics.

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 ratio, molecular weight distribution, acid value, viscosity, and glass transition temperature (Tg) are rigorously monitored. A comprehensive Certificate of Analysis (COA) detailing all relevant specifications is provided with each 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 (typically 15-25°C). Keep away from heat sources and open flame. For long-term storage, consider using under an inert atmosphere to prevent oxidation or moisture absorption, depending on the specific grade's formulation.
