CAS No. 793681-93-3 is a polyurethane oligomer with a high molecular weight. It is a colorless to light yellow transparent liquid, having a molecular weight of 880-1000, and a viscosity of 500-1000 mPa.s (25°C). It is mainly used as an additive in the production of coatings, adhesives, sealants and plastics.
It is highly compatible with many polymers, and has excellent adhesion and compatibility with most substrates. It has good hydrophobic properties, and can be used in water-based systems. It has good film-forming properties and can be used in coatings and adhesives. It can also be used in the production of polyurethane foams and elastomers.
It has good thermal stability and chemical resistance, and is resistant to oxidation and hydrolysis. It has a low volatility and low odor. It has good solubility in many organic solvents, and can be used in solvent-based formulations. It is non-toxic, and is not harmful to human health and the environment.
It has a high molecular weight, and can be used to reduce the cost of system formulations. It can also be used to improve the performance and properties of coatings, adhesives, sealants and plastics. It can also be used to improve the tensile strength, tear strength, and flexibility of polyurethanes.
