Description

1,3-Propanediol, 2-Ethyl-2-(Hydroxymethyl)-, Polymer With 1,3-Diisocyanatomethylbenzene And .Alpha.-Hydro-.Omega.-Hydroxypolyoxy(Methyl-1,2-Ethanediyl) is a high-performance, multi-component polyurethane prepolymer or polymer. This specialized chemical is engineered to deliver exceptional durability, flexibility, and adhesion properties in demanding formulations. It is a critical raw material for manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries seeking to enhance product performance.

Application

• High-Performance Coatings: Used as a key resin component in industrial, automotive, and protective coatings for superior chemical resistance, gloss, and weatherability.
• Adhesives & Sealants: Serves as a base polymer for formulating strong, flexible structural adhesives, laminating adhesives, and waterproof sealants.
• Elastomers and Castable Urethanes: A vital ingredient for producing polyurethane elastomers with tailored hardness, tensile strength, and abrasion resistance.
• Reactive Hot Melt Adhesives (RHMA): Provides excellent initial tack and final cured strength in advanced adhesive systems for packaging, textiles, and automotive assembly.
• Binder Systems: Employed in composite materials, foundry sand binders, and magnetic media for robust binding performance.
• Fiber & Textile Finishing: Used in coatings and treatments to impart water repellency, durability, and softness to technical textiles.

Quality Control

Every batch of our polyurethane polymer is produced under strict quality management protocols to ensure consistency and performance. We provide comprehensive Certificates of Analysis (COA) with key parameters such as NCO content, viscosity, solids content, and color. Our manufacturing process adheres to ISO 9001 standards, and we support compliance with relevant global regulations including REACH.

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). Keep containers tightly sealed to prevent moisture absorption and contamination, which can affect reactivity and performance. Keep away from heat, sparks, and open flame.
