Description

Oxirane, Methyl-, Polymer With Oxirane, Ether With 1,2,3-Propanetriol (3:1), Reaction Products With Tdi is a specialized polyether polyol-based prepolymer, a key intermediate in the production of high-performance polyurethane systems. This compound is engineered to deliver enhanced reactivity and tailored physical properties in the final cured material. It is primarily utilized by formulators and manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries seeking to improve product durability, flexibility, and chemical resistance.

Application

• High-Performance Polyurethane Coatings: Used as a reactive component in two-component (2K) polyurethane coatings for industrial, automotive, and marine applications, providing excellent weatherability and mechanical strength.
• Elastomer and Sealant Formulations: Serves as a prepolymer base for manufacturing flexible and rigid polyurethane elastomers, gaskets, and construction sealants with good adhesion and elasticity.
• Adhesive Binders: Acts as a key ingredient in structural and laminating adhesives, enhancing bond strength and thermal stability.
• Composite Materials: Employed in the production of fiber-reinforced plastics (FRP) and other composite materials as a matrix resin modifier.
• Footwear and Appliance Components: Used in the casting of microcellular polyurethane foams for shoe soles and durable parts for consumer appliances.

Quality Control

Our production of this polyurethane prepolymer adheres to strict quality management protocols. Every batch is analyzed to ensure consistency in key parameters such as isocyanate (NCO) content, viscosity, and hydroxyl value. Certificates of Analysis (COA) documenting these specifications are available upon request to support your quality assurance and regulatory compliance 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 / 59-77°F). This product is hygroscopic (moisture-sensitive) and must be kept under a dry, inert atmosphere (e.g., nitrogen blanket) to prevent premature reaction and degradation. Keep away from heat, sparks, and open flame.
