Description

Cyclohexane, 5-Isocyanato-1-(Isocyanatomethyl)-1,3,3-Trimethyl-, Homopolymer, Me Et Ketone Oxime-Blocked is a blocked polyisocyanate prepolymer derived from isophorone diisocyanate (IPDI). This specialized chemical is engineered to provide a latent crosslinking functionality, which is activated upon heating to release the blocking agent and form durable polyurethane networks. It is a critical raw material for formulators seeking to develop high-performance, one-component (1K) coating and adhesive systems with excellent shelf stability. Industries such as automotive, industrial maintenance, and plastics rely on this product for its ability to deliver enhanced chemical resistance, mechanical properties, and weatherability in finished products.

Application

• One-Component (1K) Polyurethane Coatings: As a latent crosslinker in high-solids, powder, and solvent-borne coatings for automotive OEM, refinish, and industrial applications.
• Adhesives and Sealants: Used in heat-curable adhesive formulations for bonding plastics, metals, and composites, offering excellent bond strength and durability.
• Industrial Maintenance Paints: Provides corrosion protection and chemical resistance in protective coatings for infrastructure, pipelines, and marine environments.
• Plastics and Elastomer Modification: Acts as a crosslinking agent to enhance the thermal and mechanical properties of engineered polymers.
• Wire and Cable Enamels: Employed in insulating varnishes and coatings that require thermal curing and robust electrical properties.
• Can and Coil Coatings: Delivers flexibility, formability, and resistance in coatings for metal packaging and pre-coated steel/aluminum.

Quality Control

Our production of blocked polyisocyanate prepolymers adheres to stringent quality management protocols to ensure batch-to-batch consistency and performance reliability. Key parameters such as blocked isocyanate content, viscosity, solids content, and deblocking temperature are rigorously tested. Certificates of Analysis (COA) documenting these specifications are provided with every shipment. Our quality system is designed to support formulators in meeting the demanding requirements of the coatings and adhesives industries.

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 moisture ingress, which can lead to premature reaction and gelation. Keep away from heat, sparks, and open flame.
