Abstract
Polyhydroxyl silanes or siloxanes useful as vehicles for coatings applicable to metal, mineral or glass surfaces, are made by reacting a silane or siloxane having an amine terminated substituent attached to silicon with an aldonic acid lactone. Reaction occurs at temperatures below 80.degree. C. in alcohol solution under inert gas blanket. Products are water soluble and polymerizable at slightly elevated temperatures to hard, water insoluble tightly adhering films.
