Abstract
Disclosed is a composition having: an organosilane polymer, a polyamide polymer; and an abrasive aggregate. The organosilane is made by: reacting an amino-functional alkoxysilane with one or more polyisocyanates to form one or more adducts having an unreacted isocyanate group; and reacting the adducts with one or more polyfunctional amino- and/or hydroxyl compounds so that the polymer contains no unreacted isocyanate groups. The polyfunctional amino- and/or hydroxyl compound has a cycloaliphatic group or an aromatic group. The composition can be used to make a single-component polysiloxane non-skid/non-slip coating that is applied by rolling, spraying, or troweling and cures with atmospheric moisture.
