GEOPOLYMERIC COATING SYSTEM FOR FIBER CEMENT PRODUCTS
The present invention relates to a geopolymer coating composition for coating fiber cement products as well as to the fiber cement products obtainable therewith. More specifically, the present invention relates to a geopolymeric coating composition comprising from about 5 to about 60% by weight of metakaolin and/or fly ash, an alkali metal (M) silicate wherein the molar ratio of SiO2 versus M2O in said alkali metal silicate is between about 1 and about 2, preferably between about 1.2 and about 1.5, and water and wherein the molar ratio of Si versus Al in said coating composition is between about 1 and about 5.5, preferably between about 2.3 and about 5.3. The invention further provides fiber cement products comprising on their outer surface one or more cured layers of said geopolymeric coating composition. The invention further provides processes for producing such fiber cement products. The present invention further relates to various uses of these fiber cement products, in particular as building materials.
