Description

Cyclohexane, 5-Isocyanato-1-(Isocyanatomethyl)-1,3,3-Trimethyl-, Homopolymer, Polyethylene Glycol Mono-Me Ether-Blocked is a specialized, blocked aliphatic polyisocyanate prepolymer designed for controlled reactivity and enhanced stability. This product is critical for formulators seeking to develop high-performance, light-stable polyurethane systems with predictable curing profiles. It is primarily utilized in advanced coating, adhesive, and elastomer applications where color retention, weatherability, and precise processing are paramount.

Application

• High-Performance Coatings: A key component in automotive clear coats, industrial maintenance paints, and coil coatings requiring exceptional gloss retention and resistance to yellowing.
• Advanced Adhesives & Sealants: Used in formulations for structural adhesives, laminating agents, and flexible sealants where controlled cross-linking and durability are essential.
• Elastomer Production: Serves as a cross-linking agent in the manufacture of specialty polyurethane elastomers for gaskets, rollers, and impact-absorbing components.
• UV-Curable Systems: Incorporated into formulations where the blocked isocyanate groups are thermally activated, enabling single-component systems with excellent shelf life.
• Textile & Leather Finishes: Provides durable, flexible finishes for synthetic leather, waterproof textiles, and other coated fabrics.
• Composite Materials: Acts as a matrix resin or modifier in fiber-reinforced plastics (FRP) and other composite structures.

Quality Control

Our production of blocked polyisocyanate prepolymers adheres to stringent 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 with every shipment. Our quality system is designed to support formulations requiring compliance with various industrial and regulatory standards.

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). Protect from moisture and humidity to prevent premature reaction and product degradation. Keep away from heat, sparks, and open flame.
