Description

α-Methyl-ω-Hydroxy Poly(Oxy-1,2-Ethanediyl) Polymer With 5-Isocyanato- 1-(Isocyanatomethyl)-1,3,3-Trimethylcyclohexane is a specialized polyether polyol pre-polymer, chemically modified with isophorone diisocyanate (IPDI) to introduce reactive isocyanate (-NCO) end groups. This product is engineered to serve as a high-performance building block for the synthesis of advanced polyurethane materials, offering precise control over polymer architecture and final properties. It is essential for formulators and manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries seeking to develop products with enhanced durability, chemical resistance, and tailored mechanical performance.

Application

• High-Performance Polyurethane Coatings: Used as a key resin component in two-component (2K) polyurethane coatings for industrial, automotive, and marine applications, providing excellent weatherability and chemical resistance.
• Specialty Adhesives & Sealants: Acts as a prepolymer in formulating structural adhesives and flexible sealants with strong bonding strength and good elongation properties.
• Elastomer Production: Serves as a precursor for casting or thermoplastic polyurethane (TPU) elastomers used in wheels, gaskets, and industrial parts requiring toughness and abrasion resistance.
• Composite Materials: Employed in the production of fiber-reinforced composites and potting compounds, where its reactivity allows for cross-linking into robust, dimensionally stable matrices.
• Waterborne Polyurethane Dispersions (PUDs): Can be used in the synthesis of aqueous polyurethane dispersions for environmentally friendly coating and adhesive systems.
• Functional Additive: Utilized as a modifier or chain extender to introduce specific properties like hydrophobicity or improved compatibility into other polymer systems.

Quality Control

Our production of α-Methyl-ω-Hydroxy Poly(Oxy-1,2-Ethanediyl) Polymer With 5-Isocyanato- 1-(Isocyanatomethyl)-1,3,3-Trimethylcyclohexane adheres to stringent quality management protocols. Each batch undergoes rigorous analytical testing to ensure consistent NCO content, viscosity, molecular weight distribution, and purity. Certificates of Analysis (COA) documenting key specifications are available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed, moisture-proof container, protected from light. Store in a cool, dry, and well-ventilated area. Due to its hygroscopic and moisture-sensitive nature, the container must be kept sealed under a dry inert atmosphere (e.g., nitrogen) to prevent premature reaction and degradation. Recommended storage temperature is 2-8°C to maximize shelf-life stability.
