Description

1,3-Butanediol, polymer with 1,3-diisocyanato-2-methylbenzene, 2,4-diisocyanato-1-methylbenzene, 2-ethyl-2-(hydroxymethyl)-1,3-propanediol and .alpha.-hydro-.omega.-hydroxypoly[oxy(methyl-1,2-ethanediyl)] Trimethylolpropane, 1,3-butanediol, polypropyleneglycol, 2,4-toluene diisocyanate, 2,6-tolylene diisocyanate polymer is a specialized polyurethane prepolymer or resin intermediate. This compound is engineered to deliver precise reactivity, tailored molecular weight, and specific functional group content for advanced material formulations. It is essential for manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries seeking to develop high-performance polyurethane systems with customized properties.

Application

• High-performance Polyurethane Coatings: Used as a key resin component in industrial, protective, and automotive coatings for enhanced durability, chemical resistance, and flexibility.
• Specialty Adhesives and Sealants: Serves as a prepolymer in formulating structural adhesives, potting compounds, and flexible sealants with strong bonding and elastic properties.
• Elastomer Production: A critical intermediate for manufacturing castable, thermoplastic, or millable polyurethane elastomers used in wheels, rollers, and gaskets.
• Composite Materials: Employed in resin systems for fiber-reinforced composites, providing toughness and impact resistance.
• Binder for Advanced Materials: Acts as a polymeric binder in the production of abrasives, nonwovens, and filtration media.
• Footwear and Apparel: Utilized in the synthesis of polyurethane components for shoe soles, insoles, and synthetic leather.

Quality Control

Our products undergo rigorous quality testing to ensure batch-to-batch consistency and compliance with industry standards. Key parameters such as isocyanate (NCO) content, viscosity, hydroxyl value, and moisture content are strictly monitored. Certificates of Analysis (COA) documenting all test results are available upon request. Our quality management system supports adherence to relevant standards for industrial chemical manufacturing.

Storage

Preserve in a tightly closed, moisture-proof 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). Keep away from heat, open flames, and sources of ignition. Under recommended storage conditions, the product is typically stable.
