Abstract
A polishing agent comprising a composition prepared by mixing PA0 (I) a polymerization product obtained by addition polymerization of a particular organohydrogenpolysiloxane and a particular organopolysiloxane having silicon-bonded aliphatic unsaturated bonds, in the presence of from 10 to 200 parts by weight of a low-viscosity silicone oil per 100 parts by weight of the total amount of said organohydrogenpolysiloxane and said organopolysiloxane; and PA0 (II) a low-viscosity oil with a viscosity of not more than 10 cSt at 25.degree. C. This polishing agent has good durable water-resistance as well as has good workability in coating operation, and therefore is suited to cars, furniture and so forth.
