Description

2-Propenoic acid, 2-hydroxyethyl ester, polymer with .alpha.-hydro-.omega.-hydroxypolyoxy(methyl-1,2-ethanediyl) and 5-isocyanato-1-(isocyanatomethyl)-1,3,3-trimethylcyclohexane is a specialized polyurethane-acrylic hybrid polymer designed for high-performance applications. This advanced copolymer combines the durability and chemical resistance of polyurethanes with the excellent weatherability and adhesion properties of acrylics. It is essential for formulators seeking to create robust, flexible, and long-lasting coatings, adhesives, and sealants. Key industries that rely on this material include automotive, industrial maintenance, and advanced material manufacturing.

Application

• High-Performance Industrial Coatings: Used as a key binder in protective coatings for metal substrates, machinery, and structural steel, offering superior corrosion and abrasion resistance.
• Automotive Topcoats and Primers: Provides excellent gloss retention, flexibility, and resistance to chemicals, fuels, and weathering in automotive refinish and OEM applications.
• Flexible and Structural Adhesives: Serves as a base polymer for formulating adhesives with high bond strength, toughness, and environmental durability.
• Specialty Sealants and Elastomers: Imparts elasticity, adhesion, and resistance to hydrolysis and UV degradation in construction and industrial sealants.
• Plastic and Composite Coatings: Enhances surface properties, including scratch resistance and weatherability, for coated plastics and composite materials.
• Wood Finishes: Used in high-end furniture and flooring finishes for its clarity, durability, and resistance to yellowing.

Quality Control

Our production of this advanced copolymer adheres to strict quality management systems to ensure batch-to-batch consistency and performance reliability. Key parameters such as monomer content, molecular weight distribution, viscosity, and functional group content are rigorously monitored. Certificates of Analysis (COA) detailing specific test results are provided with each shipment. We support compliance with global regulatory frameworks, including REACH.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at temperatures between 15°C and 25°C (59°F and 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.
