Description

2-Propenoic acid, 2-hydroxyethyl ester, polymer with .alpha.-hydro-.omega.-hydroxypoly(oxy-1,4-butanediyl) 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 flexibility and hydrolytic stability of polyether polyols with the durability and weatherability of acrylic components. It is essential for formulators seeking to create robust, flexible coatings and adhesives with enhanced chemical resistance. Key industries that rely on this material include automotive, industrial coatings, and specialty adhesives.

Application

• High-Performance Industrial Coatings: Used as a key binder in flexible, chemical-resistant topcoats for machinery, pipelines, and metal substrates.
• Automotive Coatings: Formulated into primers and clear coats that require excellent adhesion, flexibility, and resistance to environmental factors.
• Specialty Adhesives & Sealants: Serves as a base polymer for high-strength, flexible adhesives used in construction and assembly.
• Textile & Leather Finishes: Imparts durable, flexible, and water-resistant properties to coatings for fabrics and synthetic leather.
• Plastic Coatings: Enhances the surface properties of plastic components, improving scratch resistance and aesthetic appeal.
• UV-Curable Formulations: Can be adapted for use in radiation-curable systems, offering fast curing and low VOC emissions.

Quality Control

Our production of this advanced polymer adheres to strict quality management systems to ensure batch-to-batch consistency and performance. Key parameters such as molecular weight distribution, viscosity, hydroxyl value, and residual monomer content are rigorously monitored. Certificates of Analysis (COA) detailing all relevant specifications are provided with every 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 a temperature 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.
