Protective coatings
A composition for protecting a surface of an organic substrate, such as VCT, wood, or a synthetic laminate material, includes a silicate (e.g., an alkali metal polysilicate or colloidal silica) and a siliconate (e.g., a metal siliconate, such as an alkali metal methyl siliconate, etc.). In addition, the composition may include acrylic latex, a silane coupling agent, and a solvent, such as ethylene glycol monobutyl ether. Such a composition may also include a leveling agent, such as a surfactant. Organic substrates, such as VCT, wood, and synthetic laminate materials, with such a composition on their surfaces are also disclosed.
