Description

Adipic Acid, Ethylene Glycol, Propylene Glycol, Methylenebis(Phenylisocyanate) Polymer is a specialized polyurethane prepolymer or resin intermediate, identified by CAS NO 9081-28-1. This compound is engineered to deliver precise reactivity and tailored physical properties for high-performance material formulations. It is essential for manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries seeking to develop products with specific hardness, flexibility, and chemical resistance.

Application

• High-Performance Coatings & Paints: Used as a key resin component in two-component polyurethane coatings for industrial, automotive, and marine applications requiring durability and gloss.
• Adhesives & Sealants: Serves as a base polymer for formulating structural adhesives, laminating adhesives, and flexible sealants with strong bonding and weather resistance.
• Elastomers & Castable Urethanes: A critical intermediate for producing polyurethane elastomers used in wheels, rollers, gaskets, and impact-absorbing parts.
• Composite Materials: Employed as a matrix resin or binder in fiber-reinforced plastics (FRP) and other composite systems.
• Waterproofing & Construction Chemicals: Integral to formulations for membranes, coatings, and grouts that require robust waterproofing and mechanical strength.
• Industrial & Maintenance Coatings: Provides the chemical backbone for protective linings, floor coatings, and anti-corrosion paints in harsh environments.

Quality Control

Our products undergo rigorous quality testing to ensure batch-to-batch consistency and compliance with industry standards. Key parameters such as isocyanate (NCO) content, viscosity, and hydroxyl value are strictly monitored. Certificates of Analysis (COA) are available upon request, detailing all relevant specifications for your quality assurance protocols.

Storage

Preserve in a tightly closed, moisture-proof container, protected from light. Store in a cool, dry, and well-ventilated area at temperatures typically between 15-25°C (59-77°F). This material is moisture-sensitive (hygroscopic) and may react with water; ensure containers are sealed under a dry atmosphere (e.g., nitrogen) after opening to prevent degradation.
