Abstract
Disclosed and described are multi-component inorganic phosphate formulations of acidic phosphate components and basic oxide/hydroxide components. Also disclosed are high solids, atomizable compositions of same, suitable for spray coating.
Claims15
An atomizable phosphate ceramic spray system comprising
- a first component cartridge comprising an aqueous solution of an acid-phosphate of chemical formula Am(HPO4)m.nH2O, where A is hydrogen ion, ammonium cation, metal cation, or mixtures thereof;
- where m=1-3, and n=0-6;
- the first component solution adjusted to a pH of about 2 to about 5;
- a second component cartridge comprising an aqueous solution of an alkaline oxide or alkaline hydroxide represented by B2mOm, B(OH)2m, or mixtures thereof, where B is an element of valency 2m (m=1, 1.5, or 2) the second component solution adjusted to a pH of between 9-14;
- and
- optionally, a rheology modifier/suspending agent in an amount capable of providing shear thinning of either the first component or the second component and further capable of suspending a high solids content of either the first component or the second component for atomization;
- and
- high shear dispersion blade;
- and
- a plural sprayer operably connected to a pump.
