Description

Propanoic acid, 3-hydroxy-2-(hydroxymethyl)-2-methyl-, polymer with hydrazine, α-hydro-ω-hydroxypoly[oxy(methyl-1,2-ethanediyl)] and 5-isocyanato-1-(isocyanatomethyl)-1,3,3-trimethylcyclohexane is a specialized polyurethane prepolymer or resin intermediate, synthesized from a complex polyol blend and isophorone diisocyanate (IPDI). This compound matters as a high-performance building block, offering tailored reactivity and physical properties for formulating advanced polymeric materials. It is primarily needed by manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries seeking to enhance product durability, flexibility, and chemical resistance.

Application

• High-Performance Coatings: Used as a key resin component in two-component (2K) polyurethane coatings for industrial, automotive, and marine applications requiring excellent weatherability and mechanical strength.
• Specialty Adhesives & Sealants: Serves as a prepolymer in formulating moisture-curing or chemically curing polyurethane adhesives and sealants with strong bonding and elastic properties.
• Elastomer Production: Acts as an intermediate for casting or molding polyurethane elastomers used in wheels, rollers, and impact-absorbing components.
• Composite Materials: Employed in the production of fiber-reinforced composites and potting compounds, providing robust matrix properties.
• Flexible Foams & Encapsulants: Utilized in formulations for specialized flexible foams and electronic encapsulants where controlled reactivity and polymer structure are critical.

Quality Control

Our production of this polyurethane prepolymer adheres to strict quality management systems. Each batch is characterized for critical parameters including NCO content, viscosity, solids content, and color to ensure consistency and performance. Certificates of Analysis (COA) detailing these specifications are provided with every shipment. We support compliance with relevant global regulatory frameworks for industrial chemicals.

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). Keep container tightly sealed under a dry inert atmosphere (e.g., nitrogen blanket) to prevent moisture absorption and premature reaction. Isolate from sources of heat, sparks, and open flame.
