Claims37
A method of imparting anticorrosive properties to a product selected from mineral wool products and aerogel products, wherein the method comprises contacting at least a surface layer of the product with an anticorrosive composition, wherein the composition comprises:
- (a) one or more alkali metal silicate components of the formula Me2O·xSiO2, wherein x has a value of from 0.5 to 4.0,
- (b) one or more alkali metal phosphate components of the formula Me2O:nP2O5, wherein n has a value of from 0.33 to 1, and/or hydrates thereof,
- (c) one or more carboxylic acids having 6-22 carbon atoms, and/or salts thereof.
An anticorrosive composition, wherein the composition comprises:
- (a) one or more alkali metal silicate components of the formula Me2O·xSiO2, wherein x has a value of from 0.5 to 4.0,
- (b) one or more alkali metal phosphate components of the formula 2O:nP2O5, wherein n has a value of from 0.33 to 1, and/or hydrates thereof,
- (c) one or more carboxylic acids having 6-22 carbon atoms, and/or salts thereof, and wherein the composition is present on and/or in a mineral wool product or an aerogel product.
An anticorrosive composition, wherein the composition comprises:
- (a) one or more alkali metal silicate components of the formula Me2O·xSiO2, wherein x has a value of from 0.5 to 3.0,
- (b) one or more alkali metal phosphate components of the formula 2O:nP2O5, wherein n has a value of from 0.33 to 1, and/or hydrates thereof,
- (c) one or more carboxylic acids having 6-22 carbon atoms, and/or salts thereof, and wherein the composition is present on and/or in a mineral wool product or an aerogel product.
