Description

1,3-Butanediol, polymer with 1,3-diisocyanatomethylbenzene, 2-ethyl-2-(hydroxymethyl)-1,3-propanediol and .alpha.-hydro-.omega.-hydroxypolyoxy(methyl-1,2-ethanediyl) CAS NO 9038-90-8 is a specialized polyurethane prepolymer or polyol-based resin intermediate. This compound is engineered to deliver enhanced flexibility, adhesion, and chemical resistance in formulated end-products. It is primarily required by manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries seeking to develop high-performance polyurethane systems.

Application

• High-performance Polyurethane Coatings: Used as a key resin component in industrial, automotive, and protective coatings for superior durability and gloss.
• Adhesives and Sealants: Serves as a building block in formulating flexible, strong-bonding polyurethane adhesives and sealants.
• Elastomer Production: Acts as an intermediate in the manufacture of cast, thermoplastic, or millable polyurethane elastomers.
• Resin Modification: Employed to modify the properties of other polymer systems, improving impact resistance and weatherability.
• Composite Materials: Used in the production of fiber-reinforced composites for automotive and aerospace applications.
• Specialty Binders: Functions as a binder in advanced materials, including certain types of filters and abrasives.

Quality Control

Our production of this polymer intermediate adheres to strict quality management systems. Each batch is characterized for critical parameters including hydroxyl value (OHV), isocyanate content (NCO%), viscosity, and moisture content to ensure batch-to-batch consistency. Certificates of Analysis (COA) detailing these specifications are provided and available upon request 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). This product is hygroscopic (moisture-sensitive). Ensure containers are kept tightly sealed when not in use to prevent moisture absorption, which can affect product performance.
