Abstract
An anticorrosive composition comprising (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: and the use of the composition for imparting anticorrosive properties to a material such as a mineral wool product.
Claims14
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:
- 100-500 g/L Na2SiO3, 2-50 g/L sebacic acid, 20-80 g/L Na3PO4, 0.1-100 g/L of at least one surface-active compound.
An anticorrosive composition, wherein the composition comprises:
- 100-500 g/L Na2SiO3, 2-50 g/L sebacic acid, 20-80 g/L Na3PO4, 0.1-100 g/L of at least one surface-active compound,
- and wherein the composition is present on and/or in a mineral wool product or an aerogel product.
