High-build epoxy anti-corrosion primer for epoxy and polyurethane systems on vehicles, steel structures and external tank surfaces.
BUILT FOR THE JOB
PROTECT 366 is a hardener-cured epoxy anti-corrosion primer for vehicles, machines, steel structures and external tank surfaces. It combines thick-film capability with good hiding and flow, and offers chemical and mechanical resistance as part of the specified coating system. The product uses the dedicated H5966 hardener.
Choose it for work involving prepared steel, galvanised steel, aluminium or stainless steel, as well as listed existing coatings, polyester putties and laminates. For an 80-micrometre primer film at 20°C, the technical sheet gives a 45-minute wait before applying a NOVOL topcoat.
Before you specify: The mixed product has a two-hour life at 20°C. Steel requires at least 80 micrometres of epoxy primer. Follow temperature- and thickness-dependent drying times; the maximum interval without matting before topcoating is 48 hours.
