Description

1,4-Butanediol, Polymer With 5-Isocyanato-1-(Isocyanatomethyl)-1,3,3-Trimethylcyclohexane is a specialized polyurethane prepolymer derived from 1,4-butanediol and isophorone diisocyanate (IPDI). This compound is engineered to deliver exceptional weatherability, chemical resistance, and mechanical durability in high-performance coatings and elastomers. It is a critical raw material for formulators in the automotive, industrial maintenance, and specialty adhesives sectors seeking to enhance product longevity under demanding conditions.

Application

• High-Performance Coatings: Used as a key component in two-component polyurethane coatings for automotive clear coats, industrial machinery, and marine applications requiring superior gloss retention and resistance to UV light, chemicals, and abrasion.
• Elastomers and Sealants: Serves as a prepolymer in the formulation of castable and thermoplastic polyurethane elastomers for gaskets, rollers, and weather-resistant seals.
• Adhesives and Binders: Employed in structural and specialty adhesives where strong bonding, flexibility, and environmental stability are paramount.
• Industrial Maintenance Paints: A vital ingredient in protective coatings for infrastructure, pipelines, and flooring systems exposed to harsh industrial environments.
• Optical and Electronic Encapsulants: Used in potting and encapsulation compounds that require clarity, durability, and protection from moisture and thermal cycling.

Quality Control

Our production of this polyurethane prepolymer adheres to strict batch-to-batch consistency protocols. Quality is monitored through key parameters including NCO content, viscosity, and color (APHA/Hazen). A comprehensive Certificate of Analysis (COA) is provided with each shipment, detailing specifications relevant to your application. We operate a GMP-compliant quality management system to ensure reliability for critical industrial and coating formulations.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at temperatures between 15°C and 25°C (59°F and 77°F). This product is hygroscopic (moisture-sensitive). Containers must be kept tightly sealed under a dry inert atmosphere (e.g., nitrogen) to prevent moisture absorption and premature reaction. Keep away from heat, sparks, and open flame.
