Description

1,3-Propanediol, 2,2-Bis(Hydroxymethyl)-, Polymer With (Chloromethyl)Oxirane is a specialized polyol-based polymer, also known as a polyglycerol or polyether polyol derivative. This compound is valued for its reactive hydroxyl functionality, which makes it a versatile building block for creating high-performance resins and coatings. It is primarily sought by formulators in the paints & coatings, adhesives, and epoxy resin modification industries, where it contributes to enhanced flexibility, adhesion, and chemical resistance in the final products.

Application

• Epoxy Resin Modifier: Used as a reactive diluent or flexibilizer to reduce viscosity and improve the toughness and impact resistance of epoxy systems.
• Polyurethane Coatings & Elastomers: Serves as a polyol component in formulations for producing coatings, sealants, and elastomers with tailored hardness and durability.
• Adhesive & Sealant Formulations: Imparts improved adhesion and flexibility in structural and specialty adhesive applications.
• Surface Coatings: A key intermediate in the synthesis of alkyd resins and other binders for industrial and protective coatings.
• Cross-linking Agent: Functions as a cross-linker in thermosetting polymer systems to enhance network density and thermal stability.
• Chemical Intermediate: Utilized in further chemical synthesis to produce surfactants, lubricants, and other functional polymers.
