Description

Hexanedioic acid, polymer with 2,2-dimethyl-1,3-propanediol, 1,6-hexanediol, 1,1-methylenebis4-isocyanatobenzene, methyloxirane and 1,2-propanediol, Me Et ketone oxime-blocked is a specialized, blocked polyurethane prepolymer designed for controlled reactivity in advanced coating systems. This compound matters because its blocked isocyanate groups provide excellent shelf stability and latent curing properties, enabling the formulation of high-performance, one-component systems. Industrial manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) sectors require this polymer to develop products with enhanced durability, chemical resistance, and application flexibility.

Application

• One-Component (1K) Polyurethane Coatings: As a latent curing agent for industrial, automotive, and protective coatings that cure upon heating.
• High-Performance Adhesives & Sealants: For formulations requiring extended pot life and subsequent thermal activation for strong bonding.
• Wire & Cable Enamels: In the production of insulating coatings with excellent electrical properties and thermal stability.
• Textile & Leather Finishes: To create durable, flexible, and water-resistant surface coatings.
• Industrial Elastomers: For casting or molding components that demand resilience and resistance to oils and solvents.
• Powder Coatings: As a crosslinking agent in thermosetting powder formulations for metal substrates.

Quality Control

Our production of this blocked polyurethane prepolymer adheres to strict quality management protocols to ensure batch-to-batch consistency and performance reliability. Each lot is characterized for critical parameters including blocked isocyanate content, viscosity, solids content, and color. Comprehensive Certificates of Analysis (COA) documenting these specifications are provided 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). Due to its hygroscopic (moisture-sensitive) nature, containers must be kept sealed to prevent exposure to atmospheric moisture, which can lead to premature reaction and product degradation.
