Description

2-Propenoic acid, 2-methyl-, 2-hydroxyethyl ester, polymer with dichlorodimethylsilane, dichlorodiphenylsilane, methyl 2-methyl-2-propenoate, trichloromethylsilane, trichlorophenylsilane and 3-(trimethoxysilyl)propyl 2-methyl-2-propenoate is a high-performance, multi-component silicone-acrylic hybrid copolymer engineered to deliver exceptional durability and versatility. This advanced material is critical for formulators seeking to enhance the mechanical strength, weather resistance, and adhesion properties of their final products. It is primarily utilized in the production of specialized coatings, advanced adhesives, and high-performance sealants for demanding industrial and construction applications.

Application

• High-Performance Protective Coatings: Used as a key resin in architectural and industrial coatings for metal, concrete, and plastic substrates, providing excellent UV resistance, weatherability, and gloss retention.
• Specialty Adhesives & Sealants: Serves as a core component in formulating structural adhesives, pressure-sensitive adhesives (PSAs), and flexible sealants with superior bonding strength and long-term elasticity.
• Automotive & Aerospace Finishes: Incorporated into topcoat formulations to achieve a hard, scratch-resistant, and chemically durable finish for automotive clear coats and aerospace components.
• Electronic Encapsulants & Potting Compounds: Provides reliable protection as a matrix material for electronic assemblies, offering good dielectric properties and resistance to thermal cycling.
• Marine & Anti-Corrosion Coatings: Essential for heavy-duty anti-corrosion primer and topcoat systems used in marine environments, offshore structures, and chemical processing plants.
• Plastic & Composite Modification: Acts as a compatibilizer or additive to improve the impact resistance, surface finish, and processing characteristics of engineering plastics and fiber-reinforced composites.

Quality Control

Our production of this silicone-acrylic copolymer adheres to strict quality management systems, ensuring batch-to-batch consistency for critical performance parameters like viscosity, solids content, and functional group concentration. Each lot undergoes comprehensive analysis, including FT-IR for structural confirmation and GPC for molecular weight distribution. A detailed Certificate of Analysis (COA) documenting all relevant 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 temperatures between 15-25°C (59-77°F). This product is hygroscopic (moisture-sensitive); containers must be kept tightly sealed when not in use to prevent moisture absorption, which can affect product performance. Keep away from heat sources and open flame.
