Description

1,3-Propanediol, 2-Ethyl-2-(Hydroxymethyl)-, Polymer With 1,6-Diisocyanatohexane And Methyloxirane, Bisulfited is a specialized, high-performance polyurethane polyol derivative, chemically modified with a bisulfite group. This unique structure provides excellent stability, reactivity, and compatibility, making it a valuable intermediate for formulating advanced materials. It is primarily sought by manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries, as well as for producing specialty polymers and functional additives.

Application

• High-Performance Polyurethane Systems: A key reactive component for formulating coatings, adhesives, sealants, and elastomers (CASE) with enhanced properties.
• UV-Curable Coatings and Inks: Serves as a functional polyol in radiation-curable systems, contributing to film flexibility and adhesion.
• Waterborne Polyurethane Dispersions (PUDs): Used in the synthesis of stable, environmentally friendly dispersions for leather finishing, textile coatings, and wood finishes.
• Specialty Adhesives: Imparts improved tack, peel strength, and chemical resistance in structural and pressure-sensitive adhesive formulations.
• Polymer Modification: Acts as a chain extender or crosslinking agent to modify the mechanical and thermal properties of various polymers.
• Functional Additives: Utilized in the production of surfactants, dispersants, and other performance additives where hydrophilic-lipophilic balance (HLB) and reactivity are critical.
