Galvanization alone does not provide prolonged corrosion protection, as steel still suffers from white and red rust. NEI’s self-healing coating system for galvanized steel combines a self-healing pretreatment (PT-100) with a hard, durable barrier coating (TC-5001) to provide superior corrosion protection.
NANOMYTE® PT-100 is a chromate-free, self-healing conversion coating formulated for protecting zinc plated and galvanized. The thin pretreatment (~5 µm) is applied directly to the metal to prevent corrosion and improve adhesion, before applying NANOMYTE® TC-5001 or SR-500EC topcoat. Application is typically done by immersion or dipping parts into a bath of PT-100 solution.
