Description

1,3-Diazetidine-2,4-Dione, 1,3-Bis(5-Isocyanato-1,3,3-Trimethylcyclohexyl)Methyl-, Polymer With 1,4-Butanediol, 2-Ethyl-1-Hexanol-Blocked is a specialized, blocked polyisocyanate prepolymer designed for controlled reactivity in advanced coating systems. This product matters because it provides a stable, latent isocyanate source that only becomes active upon heating, enabling the formulation of high-performance, one-component (1K) polyurethane coatings. It is essential for manufacturers in the automotive, industrial maintenance, and plastics coating sectors who require durable finishes with excellent chemical resistance and weatherability.

Application

• One-Component (1K) Polyurethane Coatings: As a thermally activated crosslinker for automotive OEM and refinish paints, industrial maintenance coatings, and coil coatings.
• Powder Coatings: Serving as a blocked curing agent in thermosetting powder formulations for metals, providing excellent flow and finish.
• Adhesives and Sealants: Used in heat-curable adhesive systems for automotive, aerospace, and construction applications requiring high bond strength.
• Elastomers and Casting Resins: As a crosslinking component in the production of polyurethane elastomers, gaskets, and molded parts.
• Wire and Cable Insulation: In coatings for electrical wires that require thermal stability and insulation properties.
• Plastic Coatings: For coating plastic substrates in automotive interiors, consumer electronics, and household appliances.

Quality Control

Our production of this blocked polyisocyanate adheres to stringent quality 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 deblocking temperature. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing all test results. Our quality management system is designed to meet the demands of industrial and specialty chemical applications.

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); containers must be kept tightly sealed to prevent contact with atmospheric moisture, which can lead to premature reaction and gelation. Keep away from heat, sparks, and open flame.
