Lacquered glass, colored and opaque in appearance, is produced by depositing and then baking a coating of lacquer to one side of the glass. Lacquer is a solution of film-forming materials, natural or synthetic, usually applied as an ornamental or protective coating.
In the case of conductive materials such as metals lacquers are preferably applied by means of electrostatic lacquering. The charging of the powder lacquer particles which is required for electrostatic lacquering can take place by direct contact of the particles with high-voltage electrodes.For the electrostatic lacquering of non-conductive surfaces such as glass a layer of a conductive organic polymer from the class of the polypyrroles, polyanilines or polythiophenes is applied to the surface and this layer is then electro statically lacquered. The electrically conductive polymer dispersions can be used alone or in combination with binders such as polyurethanes, polyvinyl acetate, polyacrylates, unsaturated polyester resins or their mixtures. The binders are preferably used as aqueous dispersion or emulsion or solution. Additives such as salts of long-chain aliphatic or araliphatic sulphonic acids, lower alcohols (methanol, ethanol) can be added to the aqueous dispersions of conductive polymer and optionally binders.
Advantages of using lacquered glass:
• Lacquer applied on one side of glass enhances durability of glass.
• It has resistance to humidity making it ideal for use in high humidity rooms such as, kitchens and bathrooms.
• A better replacement to use of glass paints.
It has wide interior applications including damp and humid rooms (kitchens and bathrooms).It is ideal for use on wardrobe and cupboard doors. It is available in wide ranges of colors.
