Description

2-Propenoic acid, 2-hydroxyethyl ester, polymer with .alpha.-hydro-.omega.-hydroxypoly(oxy-1,4-butanediyl), .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 to deliver exceptional performance in demanding coating and adhesive formulations. This advanced copolymer combines the flexibility and chemical resistance of polyurethanes with the durability and weatherability of acrylics, creating a versatile material for high-performance applications. It is a critical raw material for formulators in the industrial coatings, specialty adhesives, and advanced material sectors seeking to enhance product longevity and functionality.

Application

• High-Performance Industrial Coatings: Used as a key binder in protective coatings for metal, concrete, and plastic substrates, offering excellent UV resistance, gloss retention, and protection against corrosion and chemicals.
• Automotive and Transportation Finishes: Formulated into topcoats and clearcoats that provide a durable, scratch-resistant, and aesthetically pleasing finish for vehicle exteriors and components.
• Specialty Adhesives and Sealants: Serves as a base polymer for structural and elastic adhesives requiring strong bonding, flexibility, and resistance to environmental stress.
• Wood and Furniture Coatings: Imparts a hard, clear, and protective finish that enhances the natural beauty of wood while providing resistance to abrasion, solvents, and household chemicals.
• Plastic Coatings: Applied to plastic parts in consumer electronics, appliances, and automotive interiors to improve surface hardness, feel, and color stability.
• Marine and Protective Coatings: Formulated into systems that protect structures from harsh marine environments, including saltwater, humidity, and biological fouling.

Quality Control

Our production of this advanced polymer adheres to strict quality management systems to ensure batch-to-batch consistency and performance reliability. Each lot undergoes comprehensive analysis, including tests for viscosity, solids content, color, acid value, and functional group content (NCO/OH). Certificates of Analysis (COA) documenting all critical parameters are provided with every shipment. We support compliance with relevant 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 sealed when not in use to prevent moisture absorption, which can affect product performance. Keep away from heat sources and open flames.
