Thick and durable SiO2 emulsion sealant - TANK easily deploys a hardened hydrophobic layer through a standard spray-on and wipe-off process. The expected service life of LSP is at 5 to 6 months with hydrophobics properties at 3 months contingent on AO and amount used during application. Pollution resistance reduces maintenance time and is well suited to be used as a drying aid.
