CAS No.2916-76-9 is a high-performance, water-soluble polyester polyol, which has excellent weather resistance and low viscosity. It is widely used in the production of polyurethane coatings, adhesives, sealants and elastomers.
The polyester polyol is prepared from a polyol, polyacid and a polyfunctional initiator. The polyol is a polyethylene glycol, polypropylene glycol, polylactone or polycaprolactone and can contain a variety of functional groups. The polyacid can be a dicarboxylic acid, such as adipic acid, phthalic acid, or trimellitic acid; or it can be a polycarboxylic acid, such as a polyacrylate, polymethacrylate, polyitaconate, polymaleate, polyfumarate, or polysuccinate. The polyfunctional initiator can be a diisocyanate, such as isophorone diisocyanate, or a polyisocyanate, such as hexamethylene diisocyanate.
The resulting polyester polyol has a high molecular weight and is resistant to heat, light, and oxidation. It has excellent adhesion to a variety of substrates, including metal, concrete, wood, and plastics. It is also water-soluble, making it suitable for use in water-based coatings and adhesives.
CAS No.2916-76-9 is used in the manufacture of polyurethane coatings, adhesives, sealants, and elastomers. It is used as a binder in the production of paints, varnishes, and lacquers. It is also used as a thickener in coatings, adhesives, and sealants. It can be used as a plasticizer in paints, adhesives, and sealants as well. It is also used in the production of foam insulation.
