Abstract
A non-aqueous solution-suspension of R2O—SiO2—B2O3 comprises in the dry state a composition of 2 to 30 weight percent R2O, wherein R2O is an alkali metal oxide; between 10 to 74 weight percent SiO2; and between 23 to 79 weight percent B2O3. Non-aqueous solution-suspensions are used to blend to give a liquid paint which, on drying, contains the composition within the range given above in the R2O—SiO2—B2O3 system. Non-aqueous bulk liquid and aerosol based spray paints are provided, with or without Boron Nitride additions, to allow the formation of tough, flexible coatings onto ferrous metals after bake-on.
Claims7
A liquid binder system for binding ceramic and metal systems, wherein the liquid binder system comprises:
- a non-aqueous solution-suspension of R2—O—SiO2—B2O3 comprising in a dry state, a composition of 2 to 30 weight percent R2O, wherein R2O is an alkali metal oxide;
- between 10 to 74 weight percent SiO2;
- and between 23 to 79 weight percent B2O3, suspended in liquid selected from the group consisting of ethanol, acetone and ethyl acetoacetate, and mixtures thereof.
