Abstract
Abstract Good abrasion resistance and labelability can be obtained on a glass surface by applying thereto at a temperature below 450*F. a coating consisting essentially of a mixture of a polyolefin and an ethylenediaminopropyltrialkoxysilane or a polyethyleneiminepropyltrialkoxysilane in an aqueous medium. The scratch resistant properties thus produced are synergistic compared to the use of either component of the coating composition when used alone.
