COPPER ANTIFOULING

LONG LASTING, ECONOMICAL & ENVIRONMENTALLY FRIENDLY

 

COPPERPLUS antifouling is a highly effective coating for your boat, providing long-term protection from marine growth in all waters.

 

 

Copperplus tug test 15096.pdf
This picture shows a trial patch of Copperplus that was applied to a tug that was moored in Fowey harbour for two years. When slipped the Copperplus was virtually clean while the remainder of the vessel has a thick covering of growth of all types.
Copperplus does not contain additional biocides because they would soon leach out to leave the coating less effective.

COPPERPLUS is effective in all areas and when correctly applied and maintained it is largely self cleaning on vessels which are in regular use. It will carry on working after other products have fouled.

COPPERPLUS is economical. When applied in accordance with the instructions one application of COPPERPLUS will last up to 10 years. COPPERPLUS is suitable for use on steel, GRP and wooden vessels, and because  it is non-conductive it will not cause electrolysis.

COPPERPLUS is environmentally friendly and does not contain tri-butyl-tin or any other chemicals which can leach out of the coating and poison marine life.  

COPPERPLUS mode of operation. COPPERPLUS is more effective then conventional antifouling, because on exposure to sea water copper quickly reacts with oxygen in the water to form cuprous oxide which is a powerful antifouling agent. Further exposure to sea water converts the cuprous oxide to cupric hydrochloride, which does not adhere to the underlying cuprous oxide and easily washes away with any attached growth revealing fresh cuprous oxide. This self-cleaning action is unique to products containing a very high content of metallic copper or copper alloy. The process is facilitated by the porous epoxy binder that allows a constant supply of dissolved copper to leach to the surface.

COPPERPLUS  is durable. The corrosion rate of copper antifouling in sea water depends on the speed and usage of the vessel but for commercial craft it will be between 3 and 10 microns per year. Consequently an application of COPPERPLUS 250 microns thick will last many years.

COPPERPLUS is virtually indestructible. The combination of tough epoxy binder and malleable copper produces a coating that is flexible, abrasion and impact resistant. Mechanical damage is easy to repair. Small areas can be re-coated by hand while larger areas can be spot blasted and re-sprayed.

COPPERPLUS requires very little maintenance.  It usually only requires pressure washing and repair of any mechanical damage before re-launching.

COPPERPLUS is as easy to apply as conventional antifouling. When mixed it has a 8 to 10 hour pot life and unused material can be kept in a fridge overnight. COPPERPLUS can be applied outdoors in poor weather conditions and can be immersed at any time after application without danger of impaired antifouling performance. Its resistance to mechanical damage reduces or eliminates touching up.

THE MOST EFFECTIVE COPPER ANTIFOULING ON THE MARKET:

 

COPPERPLUS is the result of extensive research to improve the performance and reliability of metallic copper-epoxy antifouling. The research has resulted in the discovery of a unique non-toxic additive that renders the epoxy binder micro-porous. Although the sponge like epoxy binder is mechanically very strong it does not trap the copper but allows it to easily leach from the entire thickness of coating to the surface, where it forms a protective film that deters all forms of fouling.   Recently a new hardener has been developed which enables Copperplus to be applied at any temperature without effecting its antifouling performance.
