Description

1,3-Butanediol Reaction Products With 1,6-Diisocyanatohexane is a specialized polyurethane prepolymer or oligomer derived from the controlled reaction of 1,3-butanediol and 1,6-diisocyanatohexane (HDI). This compound is valued for its role as a key building block in the synthesis of high-performance polyurethane materials, offering tailored reactivity and backbone structure. It is primarily needed by formulators and manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries seeking to enhance product durability, flexibility, and chemical resistance.

Application

• High-Performance Polyurethane Coatings: Serves as a crucial prepolymer for producing weather-resistant, glossy, and durable industrial, automotive, and protective coatings.
• Adhesives & Sealants: Used in formulating strong, flexible polyurethane adhesives and sealants with excellent adhesion to various substrates.
• Elastomers: Acts as a chain extender or prepolymer component in the manufacture of polyurethane elastomers for wheels, rollers, and industrial parts.
• Resin Modification: Employed to modify the properties of other polymer resins, improving toughness, crosslink density, and chemical stability.
• Binder Systems: Utilized in specialty binder applications for composites, foundry sands, and abrasives.
