Description

1,4-Butanediol, polymer with 1,3-diisocyanatomethylbenzene, 2-ethyl-2-(hydroxymethyl)-1,3-propanediol and .alpha.-hydro-.omega.-hydroxypoly[oxy(methyl-1,2-ethanediyl)] is a specialized polyurethane prepolymer or polyol, identified by CAS No. 9036-64-0. This engineered polymer is valued for its versatility as a reactive intermediate, offering formulators the ability to tailor final material properties such as flexibility, adhesion, and chemical resistance. It is essential for industrial manufacturers seeking to develop high-performance coatings, adhesives, sealants, and elastomers.

Application

This polyurethane prepolymer serves as a critical building block in advanced material synthesis. Its primary applications include:

• High-Performance Coatings: Formulation of durable, chemical-resistant, and flexible protective coatings for industrial equipment, automotive components, and flooring.
• Adhesives & Sealants: Production of strong, elastic polyurethane adhesives and sealants with excellent bonding properties for construction, automotive assembly, and marine applications.
• Elastomers and Castables: Manufacturing of polyurethane elastomers for gaskets, wheels, rollers, and impact-absorbing components.
• Composite Materials: Acting as a matrix resin or modifier in fiber-reinforced composites to enhance toughness and interfacial adhesion.
• Waterproofing Membranes: Key component in liquid-applied waterproofing systems for roofs, bridges, and concrete structures.
• Industrial Fabric Coatings: Used to coat textiles and fabrics to impart water resistance, durability, and flexibility for tarps, awnings, and protective clothing.

Quality Control

Our production of this polyurethane prepolymer adheres to strict quality management protocols to ensure batch-to-batch consistency and performance reliability. Key parameters such as isocyanate (NCO) content, hydroxyl value, viscosity, and moisture content are rigorously monitored. A comprehensive Certificate of Analysis (COA) detailing all relevant specifications is provided with each shipment to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. This material is hygroscopic (moisture-sensitive). Store in a cool, dry, and well-ventilated area at room temperature (typically 15-25°C). Ensure containers are kept sealed when not in use to prevent moisture absorption and premature reaction. Keep away from heat, sparks, and open flame.
