Abstract
A composition to produce an adherent and water insoluble deposit on substrate surfaces. A coating material for these surfaces is described which can be applied at any temperature up to at least 2000 degrees F., with the resultant deposit being highly adherent and water insoluble after short drying times. This coating has a liquid phase formed from at least water, a pre-reacted lithium silicate, and a pre-reacted potassium silicate. It can also contain a sodium silicate. This coating can be expressed as being about 69 to about 79 wt. % water and about 21 to about 31 wt. % a mixture of R.sub.2 O and SiO.sub.2. The R.sub.2 O is selected from either a mixture of Li.sub.2 O and K.sub.2 O or from a mixture of Li.sub.2 O, K.sub.2 O and Na.sub.2 O. The R.sub.2 O and SiO.sub.2 typically have a molar ratio of about 0.24 to about 0.29, and the K.sub.2 O is about 35 to 85% of the total molar amount of the R.sub.2 O. When Na.sub.2 O is present, it is up to about 10% of the total molar amount of the R.sub.2 O. To this liquid phase is added a suitable pigment or other refractory material, at about 6-80 wt. % based upon the liquid phase. A range of compositions is discussed as well as typical results.
