Description

2H-Azepin-2-one, hexahydro-, polymer with 2,4-diisocyanato-1-methylbenzene, 2-ethyl-2-(hydroxymethyl)-1,3-propanediol, methyloxirane, oxirane and 1,2,3-propanetriol CAS NO 102958-57-6 is a specialized polyurethane-polyol hybrid polymer designed for high-performance applications. This advanced material offers a unique combination of chemical resistance, mechanical strength, and formulation versatility, making it a critical component for demanding industrial processes. 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: Used as a key resin component in industrial, automotive, and protective coatings requiring excellent durability, chemical resistance, and weatherability.
• Advanced Adhesives & Sealants: Serves as a base polymer for formulating structural adhesives, potting compounds, and flexible sealants with strong bonding and elastic properties.
• Elastomer Production: Employed in the synthesis of polyurethane elastomers for gaskets, rollers, and impact-resistant parts.
• Composite Materials: Acts as a matrix resin or modifier in fiber-reinforced plastics (FRP) and other composite systems to enhance toughness and interfacial adhesion.
• Specialty Binders: Utilized in formulating binders for abrasives, non-wovens, and other industrial materials where flexibility and strength are required.
• Modifier for Other Polymers: Can be used to modify the properties of other polymer systems, improving impact strength, flexibility, or adhesion.

Quality Control

Our production of this advanced polymer adheres to strict quality management systems to ensure batch-to-batch consistency and performance reliability. Key parameters such as hydroxyl value, viscosity, acid value, and residual monomer content are rigorously monitored. A comprehensive Certificate of Analysis (COA) detailing all relevant specifications is provided with each shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. This material is hygroscopic (moisture-sensitive). Store in a cool, dry, and well-ventilated area at room temperature (typically 15-25°C). Keep the container tightly sealed when not in use to prevent moisture absorption, which can affect product performance. Store away from incompatible materials such as strong acids, bases, and oxidizing agents.
