Polyurethane catalysts can be classified into two broad categories, basic and acidic amine. Tertiary amine catalysts function by enhancing the nucleophilicity of the diol component. Alkyl tin carboxylates, oxides and mercaptides oxides function as mild Lewis acids in accelerating the formation of polyurethane.

Polyurethane dispersion, or PUD, is understood to be a polyurethane polymer resin dispersed in water, rather than a solvent, although some cosolvent may be used.Its manufacture involves the synthesis of polyurethanes having carboxylic acid functionality or nonionic hydrophiles like PEG (polyethylene glycol) incorporated into, or pendant from, the polymer backbone.

This colorless, flammable, and poisonous liquid, featuring a slight alcohol odor in its pure form, is miscible in water, ethanol, ketones, and various other organic solvents. Its principal applications include serving as an ingredient in antifreeze, dry gas, windshield washer fluids, and as a denaturant in ethanol. 13.
As its heated, the components in the retardant prevent the cellulose in plant matter from fueling the fire, according to Perimeter Solutions. It instead emits water vapor as it decomposes, which ...
For example, in the United States flammable liquids, by definition, have a flash point below 100 °F (38 °C)—where combustible liquids have a flash point above 100 °F (38 °C). Flammable solids are solids that are readily combustible, or may cause or contribute to fire through friction.
Even though liquid detergents can contain mostly water, they still have the volume advantage for surfactants and enzymes — the stuff that makes soap work. However, the disparity in performance ...
A flammable liquid is a liquid which can be easily ignited in air at ambient temperatures, i.e. it has a flash point at or below nominal threshold temperatures defined by a number of national and international standards organisations.
