Description

Tung Oil, Soybean Oil, Pentaerythritol, Toluene Diisocyanate Polymer is a specialized polyurethane prepolymer or resin derived from natural oil polyols and aromatic isocyanates. This compound is valued for its ability to impart flexibility, hydrolytic stability, and enhanced bio-based content to polyurethane systems. It is primarily needed by formulators in the coatings, adhesives, sealants, and elastomers (CASE) industries seeking sustainable performance materials.

Application

• Flexible Coatings Binder: Used in high-performance wood finishes, floor coatings, and industrial maintenance paints requiring excellent elasticity and moisture resistance.
• Adhesive & Sealant Formulation: Serves as a key component in moisture-cure and two-part polyurethane adhesives and sealants for construction and automotive assembly.
• Elastomer Production: Acts as a prepolymer in the manufacture of castable polyurethane elastomers for rollers, wheels, and impact-absorbing parts.
• Sustainable Material Modification: Incorporated into polymer systems to increase renewable content while maintaining or enhancing physical properties.
• Composite Matrix Resin: Utilized as a resin matrix in certain composite materials, offering a balance of toughness and environmental aging resistance.

Quality Control

Our products undergo rigorous quality testing to ensure batch-to-batch consistency and compliance with industry standards. Key parameters such as NCO content, viscosity, and hydroxyl value are strictly monitored. Certificates of Analysis (COA) are available upon request to support your quality assurance and regulatory needs.

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). This material is hygroscopic (moisture-sensitive); ensure containers are sealed immediately after use to prevent moisture absorption and premature reaction.
