Cold galvanising products

• 

ROCOL has launched three new products in its Cold Galvanising Spray range.

The three provide triple, long-term protection from the corrosion of ferrous metal, and are available in a range of decorative finishes – Bright, Matt and Hot Dip Finish.

They utilise an advanced resin system and a high content of ultra-pure zinc to deliver triple protection in terms of optimum cathodic defence, mechanical toughness and water resistance. Each of the products in the range offers a unique combination of flexibility and hardness, and is highly resistant to peeling, flaking and abrasion. The advanced resin system provides a durable, hydrophobic film which repels moisture away from the surface to form beads of water.

As with the original Cold Galvanising Spray, each has temperature resistance from -30° to +450 °C. Regardless of finish, each of the three products can act as a high performance coating and primer containing pure zinc, aluminium, synthetic resins and additives and like the original formula can be over-painted.


TCold Galvanising Spray Matt Triple Protection offers outstanding long-term corrosion protection for metal components requiring a permanent mid-grey coating. It features more than 70% high purity zinc in the dry film and after 2,000 hours of salt spray testing at 35°C there was zero corrosion.


Cold Galvanising Spray Bright Triple Protection features more than 45% high purity zinc in the dry film it offers the same long-term triple corrosion protection as the Matt Triple Protection and has undergone the same vigorous testing. It provides a permanent brighter light-grey coating

Cold Galvanising Spray Hot Dip Finish Triple Protection provides long-term corrosion protection for metal components requiring a permanent, bright glossy appearance with the lustre look of aluminium. It features more than 5 per cent high purity zinc and 80% aluminium. The product has undergone 1,000 hours of salt spray testing resulting in zero corrosion and like all the products in the Cold Galvanising Spray range can be used to repair the surface of galvanised products in 24 hours.
