US 2017/0283306 A1 · GLASS COMPOSITE SUITABLE FOR PROVIDING A PROTECTIVE COATING ON UNTREATED SUBSTRATES

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.

Dependent claims

A process for emplacing a glass coating on a substrate, the process comprising:

applying a glass coating system to at least one surface of a non-treated substrate;
at least one of admixing a primary frit or powder with a secondary frit or powder to form the glass coating system, or applying a secondary frit or powder composition to a surface formed by the glass coating system after the applying step;
at least one of admixing a second secondary frit or powder or applying a second secondary frit or powder to a surface formed by the secondary frit or powder composition;
sintering the glass coating system to form a glass coating therefrom on the at least one surface of the substrates;
wherein the second secondary frit comprises from about 7 wt % to about 19 wt % P2O5.
