Claims17
A method of producing a phosphate cement coating comprising:
- (a) providing a first mixture where said mixture comprises phosphoric acid, phosphoric acid salt, acid-stabilized polymer and water wherein the pH of the first mixture is ≤6.0;
- (b) providing a second mixture comprising metal oxide and/or metal hydroxide, polymeric material and water wherein said polymeric material is present at a level of 0.1% by weight to 45.0% by weight in said second mixture;
- (c) combining said first mixture and said second mixture and producing a phosphate cement coating and wherein said second mixture is prepared by combining polymeric material with water and adding said metal oxide wherein said metal oxide converts to metal hydroxide and the temperature of said second mixture does not increase by more than 60° C. from its initial temperature.
A method of producing a phosphate cement coating comprising:
- (a) providing a first mixture where said mixture comprises phosphoric acid, phosphoric acid salt, acid-stabilized polymer and water wherein the pH of the first mixture is ≤6.0;
- (b) providing a second mixture comprising metal oxide and/or metal hydroxide, polymeric material and water wherein said polymeric material is present at a level of 0.1% by weight to 45.0% by weight in said second mixture wherein said metal oxide and/or metal hydroxide, polymeric material and water are mixed for a designated period of time of 5 minutes to 9.0 hours and introducing cellulose to said second mixture;
- and
- (c) combining said first mixture and said second mixture and producing a phosphate cement coating.
