Description

Ethanol, 2,2'-oxybis-, polymer with 1,3-diisocyanatomethylbenzene, .alpha.-hydro-.omega.-hydroxypoly(oxy-1,4-butanediyl) and 1,1'-methylenebis[4-isocyanatocyclohexane] is a specialized polyurethane prepolymer or resin, designed to deliver exceptional performance in demanding industrial applications. This advanced polymer offers a unique combination of flexibility, chemical resistance, and durability derived from its multi-component structure. It is a critical raw material for formulators and manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries seeking to enhance product performance.

Application

• High-Performance Coatings: Used as a key binder in industrial and protective coatings for metal, concrete, and plastic substrates, providing excellent abrasion and chemical resistance.
• Advanced Adhesives & Sealants: Serves as a base polymer for formulating structural adhesives, potting compounds, and flexible sealants with strong bonding and environmental stability.
• Elastomer Production: A vital component in the manufacture of cast polyurethane elastomers for rollers, wheels, gaskets, and impact-absorbing parts.
• Composite Materials: Employed as a matrix resin in fiber-reinforced composites, contributing to toughness and interlaminar strength.
• Waterproofing Membranes: Formulated into liquid-applied membranes and coatings for roofing and construction due to its weatherability and seamless application.
• Flexible Foams & Cushioning: Can be used in specialized formulations for microcellular foams and energy-absorbing materials.

Quality Control

Our production of this polyurethane polymer adheres to strict quality management systems to ensure batch-to-batch consistency and performance reliability. Key parameters such as NCO content, viscosity, solids content, and color are rigorously monitored. A comprehensive Certificate of Analysis (COA) detailing 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 recommended for polyurethane materials (typically between 15°C and 25°C). This product is hygroscopic (moisture-sensitive); containers must be kept sealed to prevent contact with atmospheric moisture, which can cause premature reaction and gelation.
