CRC® Zinc It

CRC Zinc It is a weld through single component zinc-rich compound that offers the same advantages as hot-dip galvanising by forming a highly-protective coating with 95% highest purity zinc on bare steel or iron surfaces. It is ideal for repairing damaged galvanised surfaces or as a convenient and easy-to-apply alternative if hot-dip galvanising is not available.

The zinc particles fuse directly to clean metal and form an electro-chemical bond that – due to sacrificial anodisation of zinc – stops rust and rust creepage, even when scratched, abraded or dented.

The quick-drying, tough coating is resistant to salt corrosion, water and heat and makes CRC Zinc It the premium product if long-term protection in harsh conditions and highly corrosive environments is required.

CRC Zinc It provides excellent cover and is capable to be applied as a heavy film for extra protection without forming runs. Delivered from a unique aerosol system giving a smooth even coat.

Ongoing protection can be achieved through simple re-coating within 6 years, depending on conditions. Protection in extreme conditions may require re-application more frequently.

CRC Zinc It can act as a finish coat on clean iron, steel and their welds. Top-coating CRC Zinc It with another product of CRC’s Zinc coating range provides extra protection and a selection of bright metallic or coloured gloss finishes – the ultimate choice for your application.

If other colours are required, CRC Zinc It can be top-coated with most standard decorative paint systems for metals.
