Description

Oxirane, methyl-, polymer with oxirane, ether with 2-ethyl-2-(hydroxymethyl)-1,3-propanediol (3:1), polymer with .alpha.-hydro-.omega.-hydroxypolyoxy(methyl-1,2-ethanediyl) and 1,1-methylenebis4-isocyanatocyclohexane is a specialized polyurethane-polyether hybrid polymer, representing a high-performance material engineered for demanding applications. This compound matters because it combines the flexibility and hydrolytic stability of polyethers with the toughness and chemical resistance of polyurethanes, offering a unique balance of properties. It is primarily needed by formulators in the coatings, adhesives, sealants, and elastomers (CASE) industries seeking advanced performance materials.

Application

• High-Performance Coatings: Used as a key resin or modifier in industrial, automotive, and protective coatings to enhance flexibility, adhesion, and chemical resistance.
• Advanced Adhesives & Sealants: Serves as a base polymer for formulating structural adhesives, potting compounds, and flexible sealants with excellent durability.
• Specialty Elastomers: Employed in the production of castable or thermoplastic polyurethane (TPU) elastomers for gaskets, rollers, and wear-resistant parts.
• Composite Materials: Acts as a matrix resin or toughening agent in fiber-reinforced composites, improving impact strength and interlaminar adhesion.
• Encapsulation & Potting: Ideal for electronic encapsulation applications where moisture resistance, thermal stability, and electrical insulation are critical.
• Flexible Foams: Can be utilized in the formulation of specialized, high-resilience flexible polyurethane foams.

Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards. Each batch is characterized for critical parameters such as NCO/OH content, viscosity, and residual monomer levels to guarantee batch-to-batch consistency and performance. Certificates of Analysis (COA) detailing these specifications are available upon request. Our manufacturing processes adhere to ISO 9001 quality management principles.

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 hygroscopic (moisture-sensitive); containers must be kept tightly sealed to prevent moisture ingress, which can lead to premature reaction and gelation. Keep away from heat, sparks, and open flame.
