Description

1,3-Propanediol, 2-Ethyl-2-(Hydroxymethyl)-, Polymer With 5-Isocyanato-1-(Isocyanatomethyl)-1,3,3-Trimethylcyclohexane And Methyloxirane is a specialized polyol-based polymer, commonly known as a polyether polyol, derived from the reaction of trimethylolpropane (TMP), isophorone diisocyanate (IPDI), and propylene oxide. This compound is valued for its role as a key intermediate in the production of high-performance polyurethane systems, offering excellent control over final polymer properties. It is primarily sought by formulators in the coatings, adhesives, sealants, and elastomers (CASE) industries, as well as in the manufacture of flexible and rigid foams.

Application

• High-Performance Polyurethane Coatings: Serves as a crucial polyol component in two-component (2K) polyurethane coatings for automotive, industrial, and marine applications, providing enhanced durability, chemical resistance, and weatherability.
• Adhesives and Sealants: Used in formulating polyurethane-based adhesives and sealants that require strong bonding, flexibility, and resistance to environmental stress.
• Elastomers: Acts as a building block for castable and thermoplastic polyurethane elastomers used in wheels, rollers, gaskets, and other demanding mechanical parts.
• Flexible and Rigid Foams: Employed as a polyol in the synthesis of specialized polyurethane foams, influencing cell structure, density, and insulation properties.
• Resin Modification: Used to modify other polymer resins to improve flexibility, impact resistance, and adhesion characteristics.
• Cross-linking Agent: Functions as a reactive intermediate in networks requiring controlled cross-link density for tailored mechanical performance.

Quality Control

Our production of this advanced polyol adheres to strict quality management systems. Each batch is characterized for critical parameters including hydroxyl value, viscosity, isocyanate (NCO) content, and moisture to ensure consistency and performance in downstream formulations. 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. This material is hygroscopic (moisture-sensitive). Store in a cool, dry, and well-ventilated area at room temperature (typically 15-25°C). Keep the container tightly sealed when not in use to prevent moisture absorption and potential reaction with atmospheric humidity.
