Zinc Chloride
Zinc chloride, in combination with water-soluble alkali metal silicate, is used to coat substrates normally infested by algae.
Description
Zinc chloride is used to prevent or minimize algal infestation that imparts a dark, unsightly appearance on surfaces such as concrete roofing tiles and other silicate-containing building materials. It is also one of the three components to prepare color development materials used for pressure-sensitive copying papers and thermo-sensitive recording papers.
