Description

Polyoxy(methyl-1,2-ethanediyl), .alpha.-hydro-.omega.-hydroxy-, polymer with 1,1-methylenebis4-isocyanatocyclohexane and .alpha.,.alpha.,.alpha.-1,2,3-propanetriyltris.omega.-hydroxypolyoxy(methyl-1,2-ethanediyl) is a specialized polyurethane prepolymer or polyol-based polymer, widely recognized for its excellent film-forming, adhesive, and elastomeric properties. This high-performance material is crucial for formulating products that require durability, flexibility, and chemical resistance. It is primarily sought after by manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries, as well as for advanced composite materials and specialty polymer applications.

Application

• High-Performance Coatings: Used as a key resin component in protective and decorative coatings for automotive, industrial, and marine applications, offering enhanced weatherability and chemical resistance.
• Adhesives & Sealants: Serves as a base polymer for formulating structural adhesives, potting compounds, and flexible sealants with strong bonding strength and elasticity.
• Elastomers and Castable Urethanes: A fundamental building block for manufacturing polyurethane elastomers, gaskets, rollers, and impact-absorbing components.
• Composite Materials: Acts as a matrix resin or modifier in fiber-reinforced plastics (FRP) and other composite systems to improve toughness and interlayer adhesion.
• Textile and Leather Finishing: Employed in coatings and binders to provide fabrics and leather with water resistance, abrasion resistance, and a soft hand feel.
• Flexible Foams and Cushioning: Can be utilized in the production of specialized, high-resilience flexible polyurethane foams.

Quality Control

Our production of this polymer adheres to strict quality management systems to ensure batch-to-batch consistency and performance reliability. Key parameters such as NCO content, viscosity, hydroxyl value, and color 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, and well-ventilated area at room temperature (15-25°C/59-77°F). This product is hygroscopic (moisture-sensitive); containers must be kept sealed to prevent moisture absorption, which can affect product performance. Keep away from heat sources and open flame.
