Composition for concealing graze marks on glass

摘要

A composition for concealing grazes or scratches on glass surfaces comprising an emulsion of composition (A) and composition (B), said composition (A) comprising the emulsion-polymerization product of: (1) 0.1-60 weight percent of (A) of the reaction product of: (a) 0.1-50 weight percent of (a) and (b) of the product obtained by reacting: (i) 1 mole of a compound of the formula Q1NHR1SiRa2(OR)3-a with (ii) 0.5-3.0 moles of a compound of the formula Q2R4SiRa2(OR)6)3-b; (b) 50-99.9 weight percent of (a) and (b) of a polydiorganosiloxane having at least one silanol group and a viscosity at 25 DEG C. of 5-10,000 cSt; (2) 1-50 weight percent of (A) of a compound of the formula (R7R8SiO)n; (3) 0.1-20 weight percent of (A) of a cationic surfactant or mixture of cationic and nonionic surfactants; (4) 20-90 weight percent of (A) of water; and (5) an effective amount of alkali metal hydroxide having catalytic ability; and said composition (B) being obtained by emulsifying in water a polydiorganosiloxane having a viscosity at 25 DEG C. of 10-100,000 cSt in the presence of a cationic or nonionic surfactant or mixture thereof.
