Description

Poly(oxy-1,2-ethanediyl), .alpha.-hydro-.omega.-hydroxy-, polymer with 1,3-diisocyanatomethylbenzene and .alpha.-hydro-.omega.-hydroxypoly[oxy(methyl-1,2-ethanediyl)] is a specialized polyurethane prepolymer or block copolymer, widely utilized for its excellent film-forming, adhesive, and elastomeric properties. This compound is engineered to deliver superior performance in demanding applications where durability, flexibility, and chemical resistance are paramount. It is a critical raw material for formulators and manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries, as well as in advanced material science.

Application

• High-Performance Coatings: Used as a key binder in industrial, protective, and specialty coatings requiring abrasion resistance, weatherability, and chemical stability.
• Adhesives & Sealants: Serves as a base polymer for formulating structural adhesives, flexible sealants, and pressure-sensitive adhesives with strong bonding strength.
• Elastomers and Castables: A precursor for manufacturing polyurethane elastomers, gaskets, rollers, and impact-absorbing components.
• Textile and Leather Finishing: Imparts durable, flexible, and water-resistant finishes to fabrics and synthetic leather.
• Composite Materials: Acts as a matrix or modifier in polymer composites to enhance toughness and interfacial adhesion.
• Encapsulation and Potting Compounds: Used in electronics and electrical applications for protecting components due to its good insulating and protective properties.

Quality Control

Our production of this polyurethane polymer adheres to strict quality management systems. Each batch undergoes comprehensive analytical testing to ensure consistency in key parameters such as isocyanate (NCO) content, viscosity, and hydroxyl value. Certificates of Analysis (COA) documenting these specifications are provided with every shipment. We support compliance with relevant industry standards for raw materials used in formulated products.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (typically 15-25°C). This material is moisture-sensitive (hygroscopic) and may react with atmospheric moisture; ensure containers are sealed when not in use. Keep away from strong acids, bases, and oxidizing agents.
