Description

1,3-Propanediol, 2-ethyl-2-(hydroxymethyl)-, polymer with 5-amino-1,3,3-trimethylcyclohexanemethanamine, 1,6-diisocyanatohexane and methyloxirane, Me Et ketone oxime-blocked is a specialized blocked polyurethane prepolymer designed for high-performance coating systems. This advanced chemical offers a unique combination of stability and reactivity, enabling the formulation of durable, one-component coatings that cure upon heating. It is essential for manufacturers seeking to enhance product longevity and performance in demanding environments. Key industries that rely on this polymer include automotive, industrial maintenance, and protective coatings.

Application

• One-Component (1K) Polyurethane Coatings: Serves as the primary resin component in heat-curable industrial and protective coatings.
• Automotive OEM and Refinish: Used in clearcoats, basecoats, and primer surfaces for excellent gloss, chemical resistance, and weatherability.
• Industrial Maintenance Coatings: Formulated into high-build coatings for structural steel, pipelines, and concrete in corrosive environments.
• Plastic Coatings: Provides adhesion and flexibility for coatings on automotive plastics, consumer electronics, and industrial components.
• Wood Finishes: Used in high-performance furniture, flooring, and cabinet coatings requiring superior hardness and scratch resistance.
• Adhesives and Sealants: Acts as a base polymer for formulating moisture-curing or heat-activated adhesives with strong bonding properties.
• Coil and Can Coatings: Employed in coatings for metal packaging and pre-coated metal sheets due to its excellent flow and cure properties.

Quality Control

Our production of this blocked polyurethane prepolymer adheres to strict quality management systems. Every batch undergoes comprehensive analytical testing, including measurement of blocked isocyanate content, viscosity, solids content, and color, to ensure batch-to-batch consistency and performance reliability. Certificates of Analysis (COA) documenting all key parameters are provided and available upon request to support your quality assurance and regulatory compliance needs.

Storage

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