Abstract: A porcelain enamel composition may include a glass component including: at least one alkali oxide in an amount ranging from about 6 to 21 wt %, SiO2 in an amount ranging from about 20 to 50 wt %, ZnO in an amount ranging from about 0.1 to 10 wt %, Al2O3 in an amount ranging from about 5 to 20 wt %, B2O3 in an amount ranging from about 0.1 to 20 wt %, and P2O5 in an amount ranging from about 5 to 30 wt %, all weight percentages expressed relative to the enamel composition. Methods of using such compositions and formed products are also described.

Abstract: Disclosed herein are refractory coating compositions with improved drying times, defect prevention, and gas permeability and methods for using such refractory coating compositions.

Abstract: Glass composite coating systems herein may be used for industrial applications serving as a chemical barrier against substrate oxidation or other deterioration by corrosive agents, may prevent material build-up in process piping and equipment, may provide for improved bonding strength between concrete and reinforcing media, and may inhibit microbial build-up on exposed surfaces. Traditionally, glass coatings are emplaced on relatively pristine, pre-prepared surfaces. Glass composite coating systems described herein may be bonded to untreated substrates, without the need to clean, polish and/or pre-treat the substrate.
