Description

1,4-Cyclohexanedimethanol, polymer with 1,3-butanediol, 1,3-diisocyanatomethyl benzene, 2-ethyl-2-(hydroxymethyl)-1,3-propanediol and .alpha.-hydro-.omega.-hydroxypoly[oxy(methyl-1,2-ethanediyl)] is a specialized polyurethane prepolymer or resin, identified by CAS 67816-00-6. This compound is engineered to deliver enhanced flexibility, chemical resistance, and adhesion properties in demanding formulations. It is primarily sought after by manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries for producing high-performance, durable end-products.

Application

• High-Performance Coatings: Used as a key component in polyurethane-based industrial, automotive, and protective coatings for superior durability and chemical resistance.
• Advanced Adhesives & Sealants: Serves as a prepolymer in formulating structural adhesives, flexible sealants, and bonding agents with excellent adhesion to diverse substrates.
• Elastomer Production: A vital raw material for manufacturing castable polyurethane elastomers used in rollers, wheels, and industrial parts requiring toughness.
• Resin Modification: Employed to modify the properties of other polymer systems, improving flexibility, impact resistance, and weatherability.
• Composite Materials: Utilized in the production of fiber-reinforced composites for applications demanding a strong, resilient matrix.
• Encapsulation & Potting Compounds: Acts as a base resin for electronic encapsulation and potting, providing protection against moisture and mechanical stress.

Quality Control

Our production of this polyurethane polymer adheres to strict quality management systems. Every batch is characterized for critical parameters to ensure consistency and performance. Certificates of Analysis (COA) detailing specifications such as NCO content, viscosity, and hydroxyl value 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 / 59-77°F). This material is hygroscopic (moisture-sensitive); containers must be kept sealed to prevent moisture absorption, which can affect product performance. Keep away from heat sources and open flame.
