Description

1,2-Propanediol, Polymer With 2-Ethyl-2-(Hydroxymethyl)-1,3-Propanediol, 1,1'-Methylenebis[4-Isocyanatobenzene], Methyloxirane And Oxirane is a specialized polyurethane-polyether hybrid polymer, synthesized from a precise combination of diols, diisocyanates, and epoxides. This engineered material is valued for its versatile reactivity and ability to form durable, flexible polymeric networks, making it a critical intermediate for high-performance formulations. It is primarily sought by manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries, as well as for advanced composite materials.

Application

• High-Performance Coatings & Paints: Acts as a key polyol component in two-component polyurethane coatings, providing excellent flexibility, chemical resistance, and adhesion for industrial, automotive, and marine finishes.
• Adhesives & Sealants: Used in formulating structural and elastic polyurethane adhesives and sealants that require strong bonding, durability, and resistance to environmental stress.
• Elastomers & Castable Urethanes: Serves as a prepolymer or curative component in the production of polyurethane elastomers for wheels, rollers, gaskets, and impact-absorbing parts.
• Composite Materials: Functions as a matrix resin or modifier in fiber-reinforced plastics (FRP) and other composites, enhancing interfacial bonding and mechanical properties.
• Flexible Foams & Cushioning: Can be utilized in specialized flexible polyurethane foam formulations where tailored reactivity and polymer structure are required.
• Industrial Resins & Binders: Employed in resin systems for industrial casting, potting, and encapsulation applications.

Quality Control

Our production of this advanced polymer adheres to strict batch-to-batch consistency protocols. Quality is verified through parameters including hydroxyl value, isocyanate content (NCO%), viscosity, and moisture content. A comprehensive Certificate of Analysis (COA) is provided with each shipment, detailing the specific specifications for your order. We operate under a robust Quality Management System to ensure reliability for your critical formulations.

Storage

Preserve in a tightly closed container, protected from light. This product is hygroscopic (moisture-sensitive). Store in a cool, dry, and well-ventilated area at room temperature (15-25°C / 59-77°F). Keep the container tightly sealed when not in use to prevent moisture absorption and potential premature reaction. Store away from heat, sparks, and open flame.
