Description

Poly[Oxy(Methyl-1,2-Ethanediyl)], α,α',α''- 1,2,3-Propanetriyltris[ω-Hydroxy-, Polymer With 5-Isocyanato-1-(Isocyanatomethyl) -1,3,3-Trimethylcyclohexane is a high-performance, cross-linked polyol-isocyanate polymer. This specialized material is engineered to deliver exceptional structural integrity and reactivity, making it a critical component in advanced formulations. It is primarily sought after by manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries for developing durable, high-performance end products.

Application

• High-Performance Polyurethane Coatings: Serves as a key resin component for industrial, automotive, and protective coatings requiring excellent chemical resistance, hardness, and weatherability.
• Advanced Adhesives & Sealants: Used in formulating structural adhesives and high-strength sealants for aerospace, automotive, and construction applications.
• Elastomer Production: A precursor for manufacturing specialized polyurethane elastomers with tailored properties like abrasion resistance and mechanical strength.
• Composite Materials: Functions as a matrix resin or cross-linking agent in fiber-reinforced composites for lightweight, high-strength components.
• Encapsulation & Potting Compounds: Employed in electronics and electrical industries to create protective, insulating barriers for sensitive components.
• Binder Systems: Acts as a reactive binder in foundry sands, abrasives, and other composite systems where thermal and mechanical stability are paramount.

Quality Control

Our production of this polymer adheres to strict quality management systems to ensure batch-to-batch consistency and performance reliability. Key parameters such as NCO content, hydroxyl value, viscosity, and equivalent weight are rigorously monitored. Certificates of Analysis (COA) documenting full specifications are provided with each shipment 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 temperatures between 15°C and 25°C (59°F and 77°F). This material is moisture-sensitive (hygroscopic); containers must be kept sealed to prevent contact with atmospheric moisture, which can lead to premature reaction and gelation.
