Description

1,2-Ethanediol, Polymer With 1,3-Diisocyanatomethylbenzene, 2-Ethyl-1-Hexanol- And Methanol Blocked is a specialized blocked polyurethane prepolymer designed for controlled reactivity in high-performance coating systems. This product matters because it provides a stable, one-component resin that only cures upon heating, releasing blocking agents to form durable polyurethane networks. Industrial formulators and manufacturers in the coatings and adhesives sectors need this material to develop products with excellent shelf stability, mechanical properties, and chemical resistance.

Application

• As a key resin component in high-temperature cure industrial coatings for automotive, aerospace, and appliance finishes.
• In the formulation of one-component (1K) polyurethane adhesives and sealants requiring excellent pot life and on-demand curing.
• For producing wire enamels and insulating varnishes that demand thermal stability and electrical insulation properties.
• As a crosslinking agent in specialty elastomers and castable polyurethane products.
• In the manufacture of corrosion-resistant protective coatings for metal substrates in harsh environments.
• For textile and leather finishing coatings to provide water resistance, durability, and a high-quality feel.

Quality Control

Our production of this blocked prepolymer adheres to strict quality management protocols to ensure batch-to-batch consistency and performance reliability. Key parameters such as blocking agent content, free isocyanate level, viscosity, and solids content are rigorously tested. Certificates of Analysis (COA) documenting these specifications are 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 material is hygroscopic (moisture-sensitive); ensure containers are sealed immediately after use to prevent exposure to atmospheric moisture, which can lead to premature reaction and product degradation.
