Description

2H-Azepin-2-One, Hexahydro-, Polymer With 2-Ethyl-2-(Hydroxymethyl)-1,3-Propanediol And 5-Isocyanato-1-(Isocyanatomethyl)-1,3,3-Trimethylcyclohexane is a specialized polyurethane prepolymer or resin intermediate derived from caprolactam, a polyol, and isophorone diisocyanate (IPDI). This compound is engineered to deliver enhanced durability, chemical resistance, and tailored reactivity for high-performance coating and adhesive formulations. It is primarily required by manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries seeking to develop products with superior weatherability and mechanical properties.

Application

• High-performance industrial and automotive coatings requiring excellent gloss retention and resistance to chemicals and abrasion.
• Formulation of specialty adhesives and sealants with strong bonding strength and flexibility for construction or automotive assembly.
• Manufacturing of cast or thermoplastic polyurethane elastomers (TPU) for gaskets, wheels, and industrial parts.
• UV-curable resin systems for wood, plastic, or metal finishes that demand fast curing and a hard, durable surface.
• Production of corrosion-resistant protective linings and primers for metal substrates in harsh environments.
• Component in ink and overprint varnish formulations to improve adhesion and scuff resistance.

Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards. Every batch is controlled for key parameters such as NCO content, viscosity, and solids content to guarantee batch-to-batch consistency for your formulations. Certificates of Analysis (COA) are available upon request, detailing the specific results for your shipment.

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). Keep away from heat, sparks, and open flame. This material is moisture-sensitive; ensure containers are sealed to prevent exposure to atmospheric humidity.
