Abstract
Disclosed is a method of preventing adhesion of organisms characterized by coating a substrate with a coating composition comprising as its vehicle component a reaction product of a silane compound and/or a low condensation product thereof and an organic compound having at least two hydroxyl groups per molecule, the silane compound being represented by the formula (R.sup.1).sub.n Si--(OR.sup.2).sub.4-n wherein R.sup.1 is alkyl having 1 to 20 carbon atoms, haloalkyl having 1 to 12 carbon atoms, cycloalkyl having 3 to 7 carbon atoms, aryl or aralkyl having an alkyl portion with 1 to 12 carbon atoms, R.sup.2 is a hydrogen atom, alkyl having 1 to 8 carbon atoms, cycloalkyl having 3 to 7 carbon atoms or haloalkyl having 1 to 8 carbon atoms and n is an integer of 0 to 3.
Claims14
A method of preventing adhesion of organisms to a substrate comprising coating the substrate with a coating composition consisting essentially of, as its vehicle component, a reaction product of 5 to 95 wt.% of a silane compound and/or a low condensation product thereof having a number average molecular weight of up to about 10,000 and 95 to 5 wt% of an organic compound having at least two hydroxyl groups per molecule, the silane compound being represented by the formula
- (R.sup.1.sub.n Si-OR.sup.2).sub.4-n
- wherein R.sup.1 is an alkyl having 1 to 20 carbon atoms, haloalkyl having 1 to 12 carbon atoms, cycloalkyl having 3 to 7 carbon atoms, aryl or aralkyl having an alkyl portion with 1 to 12 carbon atoms, R.sup.2 is a hydrogen atom, alkyl having 1 to 8 carbon atoms, cycloalkyl having 3 to 7 carbon atoms or haloalkyl having 1 to 8 carbon atoms and n is an integer of 0 to 3.
A method of preventing adhesion of organisms to a substrate comprising coating the substrate with a coating composition consisting essentially of, as its vehicle component, a reaction product of a silane compound and/or a low condensation product thereof having a number average molecular weight of up to about 10,000, an organic compound having at least two hydroxyl groups per molecule and a monohydric phenolic compound, the silane compound being represented by the formula
- (R.sup.1.sub.n Si-OR.sup.2).sub.4-n
- wherein R.sup.1 is alkyl having 1 to 20 carbon atoms, haloalkyl having 1 to 12 carbon atoms, cycloalkyl having 3 to 7 carbon atoms, aryl or aralkyl having an alkyl portion with 1 to 12 carbon atoms, R.sup.2 is a hydrogen atom, alkyl having 1 to 8 carbon atoms, cycloalkyl having 3 to 7 carbon atoms or haloalkyl having 1 to 8 carbon atoms and n is an integer of 0 to 3, the weight ratio of the silane compound and low condensation product thereof to the hydroxyl-containing organic compound being 5 to 95 wt% of the former and 95 to 5 wt.% of the latter, the monohydric phenolic compound being used in an amount of about 5 to about 900 parts by weight per 100 parts by weight of the combined amount of the silane compound and/or low condensation product thereof and the hydroxyl-containing organic compound.
