To obtain the subject composition containing a polymer terminated with an alkoxysilane, a silica-based filler and a condensation catalyst and useful for protecting a surface from the staining with organism.
The silicone composition contains (A) a polymer terminated with a alkoxysilane and preferably expressed by the formula (R groups are each independently a 1-10C alkyl, an alkoxy, a haloalkyl or vinyl; R1 group are each independently a 1-10C alkyl, etc., (n) is an integer of about 25-5,000), (B) a silica-based filler (preferably fumed silica) and (C) a condensation catalyst (preferably diisopropoxybis-2, 4-pentanedionatotitanium (IV), dibutyltin-bis- acetylacetonate or dibutyltin dilaurate). The composition is free from volatile organic compound, has a viscosity of about <30,000cps, preferably about <20,000cps at ambient temperature and is applied by spraying.
