Claims40
A phosphate cement coating precursor system comprising:
- (a) a first mixture where said mixture comprises phosphoric acid, phosphoric acid salt, acid-stabilized polymer and water wherein the pH of said first mixture is ≤6.0;
- and
- (b) a second mixture comprising metal oxide and/or metal hydroxide and water.
A phosphate cement coating precursor system comprising:
- (a) a first mixture wherein said mixture comprises phosphoric acid, phosphoric acid salt and water;
- and
- (b) 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.
A phosphate cement coating precursor system comprising:
- (a) 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;
- and
- (b) a second mixture comprising metal oxide and/or metal hydroxide, polymeric material and water.
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;
- and
