Description

1,3-Propanediol, 2-(Hydroxymethyl)-2-Methyl-, Polymer With (Chloromethyl)Oxirane CAS NO 68460-21-9 is a specialized polyether polyol, a key reactive intermediate in advanced polymer synthesis. This compound matters for its ability to impart specific properties like flexibility, hydrophilicity, and reactivity into final polymer matrices, enabling tailored performance. It is primarily needed by formulators and manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries, as well as in the production of specialty resins and functional fluids where precise molecular architecture is critical.

Application

• As a reactive polyol component in the formulation of high-performance polyurethane coatings and elastomers.
• As a building block for synthesizing waterborne resin dispersions used in eco-friendly industrial and architectural paints.
• In the production of specialty adhesives and sealants, contributing to enhanced adhesion and mechanical properties.
• As a modifier or crosslinking agent in epoxy resin systems to adjust flexibility and chemical resistance.
• In the manufacture of functional fluids, such as lubricants or hydraulic fluids, where its polymeric structure provides desired viscosity and stability.
• As an intermediate for creating surfactants or demulsifiers in the oil & gas and agrochemical sectors.
