Abstract
Organopolysiloxane polyethers with increased resistance to hydrolysis are prepared. Furthermore, a method of rendering an aqueous system hydrolysis-resistant and exhibiting increased wetting property utilizing such polysiloxane polyethers as wetting agents in aqueous systems is described. Aqueous coating systems containing such polyethers exhibit increased wetting property and are resistant to alkaline and acidic hydrolysis.
