Boiler Lizard contains vapor-phase corrosion inhibitor powder in a polyvinyl alcohol (PVA) water-soluble bag. The corrosion inhibitor powder is free of phosphates, heavy metals, nitrites and free amines. Designed for dry lay-up of boilers, the chemical protects metals in enclosed spaces. The corrosion inhibitor vaporizes and adsorbs on all metal surfaces, reaching all recessed areas and interior cavities and eliminating the need for nitrogen blankets, silica gel and hydrazine. It can be applied easily and does not need to be removed before restarting the boiler. One bag protects a 1,000-gal capacity system.
