Description

Hexanedioic acid, polymer with 5-amino-1,3,3-trimethylcyclohexanemethanamine, 2,2-dimethyl-1,3-propanediol, 1,6-hexanediol, 4,4'-methylenebis[cyclohexanamine] and 1,1'-methylenebis[4-isocyanatocyclohexane], Me Et ketone oxime-blocked is a specialized, blocked polyurethane prepolymer designed for high-performance coating systems. This advanced material offers a unique balance of chemical resistance, durability, and controlled reactivity, making it a critical component for formulating industrial finishes. It is primarily utilized by manufacturers in the coatings, adhesives, and specialty polymers industries seeking to enhance product longevity and performance under demanding conditions.

Application

• High-Performance Industrial Coatings: Used as a key resin component in two-component (2K) polyurethane coatings for automotive, aerospace, and heavy-duty machinery, providing excellent gloss retention, chemical resistance, and weatherability.
• Corrosion-Resistant Primers and Topcoats: Formulated into protective coatings for metal substrates, bridges, pipelines, and offshore structures where durability against harsh environments is paramount.
• Adhesives and Sealants: Serves as a base polymer in high-strength, flexible adhesives and sealants for construction, automotive assembly, and composite bonding applications.
• Plastic and Composite Coatings: Provides superior adhesion and finish for coatings applied to plastics, fiberglass, and other composite materials.
• Wood Finishes: Used in high-quality, durable clear coats and pigmented finishes for furniture, flooring, and architectural woodwork.
• Specialty Elastomers and Castables: Acts as a precursor in the production of polyurethane elastomers, gaskets, and molded parts requiring specific mechanical properties.

Quality Control

Our blocked polyurethane prepolymers are manufactured under strict quality management systems to ensure batch-to-batch consistency and performance reliability. Each lot undergoes rigorous analytical testing, including measurement of NCO content (blocked), viscosity, solids content, and color. Certificates of Analysis (COA) detailing these specifications are provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at temperatures between 15°C and 25°C (59°F and 77°F). Keep away from strong acids, organic solvents, and sources of heat or ignition. Under these conditions, the product is typically stable for 12 months from the date of manufacture. Always check the specific label or technical data sheet for the recommended shelf life.
