Abstract
Official abstract text for this publication.
An anticorrosive composition comprising (a) one or more alkali metal silicate components of the formula Me 2 O·xSiO 2 , wherein x has a value of from 0.5 to 4.0, (b) one or more alkali metal phosphate components of the formula Me 2 O:nP 2 O 5 , 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.
First claim
Opening claim text (preview).
What is claimed is: 1. An anticorrosive composition, wherein the anticorrosive composition comprises 100-500 g/L Na 2 SiO 3 , 2-50 g/L sebacic acid, 20-80 g/L Na 3 PO 4 , and 0.1-100 g/L surface-active compound. 2. The anticorrosive composition of claim 1 , wherein the surface-active compound is selected from soaps and surfactants. 3. The anticorrosive composition of claim 1 , wherein the surface-active compound is selected from alkali stable water dispersible surfactants, alkali stable water soluble surfactants, and emulsifying surfactants. 4. The anticorrosive composition of claim 1 , wherein the anticorrosive composition further comprises a hydrophobic agent comprising at least one silicone compound. 5. The anticorrosive composition of claim 1 , wherein the anticorrosive composition further comprises one or more water-miscible organic solvents. 6. A method of imparting anticorrosive properties to a product selected from mineral wool products and aerogel products, wherein the method comprises contacting the product with the anticorrosive composition of claim 1 . 7. The anticorrosive composition of claim 1 , wherein the anticorrosive composition is dispersed in a mineral wool product. 8. The composition of claim 7 , wherein the mineral wool product is selected from a pipe section, a roof product, a facade product, a mat, and a wired mat. 9. The anticorrosive composition of claim 1 , wherein the anticorrosive composition imparts anticorrosive properties to a mineral wool product and/or an aerogel product.
