Description

1,6-Hexanediol, polymer with 5-amino-1,3,3-trimethylcyclohexanemethanamine, .alpha.-hydro-.omega.-hydroxypoly(oxy-1,4-butanediyl) and 5-isocyanato-1-(isocyanatomethyl)-1,3,3-trimethylcyclohexane, N-butyl-1-butanamine-blocked is a specialized blocked polyisocyanate prepolymer, a key intermediate in the formulation of high-performance polyurethane coatings and adhesives. This compound matters for its ability to provide controlled reactivity, enabling the development of one-component (1K) systems that cure upon heating to release the active isocyanate groups. It is primarily needed by formulators in the automotive, industrial coatings, and specialty adhesive sectors seeking enhanced pot life, storage stability, and precise curing profiles.

Application

• One-Component (1K) Polyurethane Coatings: As a latent crosslinker in automotive OEM and refinish coatings, industrial maintenance paints, and plastic coatings that cure at elevated temperatures.
• Powder Coatings: Utilized in hybrid or pure polyurethane powder coating formulations to improve flow, gloss, and chemical resistance.
• High-Performance Adhesives & Sealants: Serves as a blocked curing agent in heat-activated structural adhesives, film adhesives, and sealants requiring excellent durability.
• Coil and Can Coatings: Provides crosslinking functionality in coatings for metal substrates, offering good flexibility and corrosion resistance.
• Electrical Insulating Varnishes: Used in wire enamel and impregnating varnishes for motors and transformers due to its thermal cure properties.
• Textile and Leather Finishes: Imparts durable, flexible, and water-resistant properties to synthetic leather and technical textiles.

Quality Control

Our blocked polyisocyanate prepolymers are manufactured under strict process controls to ensure batch-to-batch consistency critical for formulation stability. Quality is verified through parameters including blocked isocyanate content, viscosity, solvent content, color, and deblocking temperature. Certificates of Analysis (COA) detailing these specifications are provided with each shipment. Production adheres to a quality management system, supporting compliance with relevant global regulatory frameworks for industrial chemicals.

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). 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.
