Description

2-Oxepanone, Polymer With 1,4-Butanediol, 1,3-Diisocyanatomethylbenzene, 2-Ethyl-2-(Hydroxymethyl)-1,3-Propanediol And 2,2'-Oxybis[Ethanol] is a specialized polyurethane prepolymer or resin, synthesized from a precise blend of caprolactone, diols, and a diisocyanate. This engineered polymer is valued for its excellent mechanical properties, chemical resistance, and versatile processing characteristics, making it a critical raw material for high-performance coatings and elastomers. It is primarily needed by formulators in the coatings, adhesives, sealants, and elastomers (CASE) industries seeking to enhance product durability and functionality.

Application

• High-performance polyurethane coatings for industrial, automotive, and marine applications requiring abrasion and chemical resistance.
• Elastomer and sealant formulations where flexibility, tensile strength, and weatherability are critical.
• Adhesive systems designed for bonding diverse substrates, including metals, plastics, and composites.
• Specialty resin components for composite materials and potting compounds in electrical or electronic applications.
• Modifier for other polymer systems to improve impact resistance, adhesion, or processing windows.
• Fabric coatings and textile finishes that demand durability and specific hand-feel properties.

Quality Control

Our production of this polyurethane polymer adheres to strict batch-to-batch consistency protocols. Quality is verified through parameters including NCO content, hydroxyl value, viscosity, and color. A comprehensive Certificate of Analysis (COA) is provided with each shipment, detailing specifications and test results to ensure the material meets your formulation requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (typically 15-25°C). This material is moisture-sensitive; containers must be kept sealed to prevent reaction with atmospheric moisture. Keep away from heat sources and open flame.
