Propshield Stern Gear Antifouling Grease

Propshield Antifouling Grease whilst still in its infancy is fast becoming known throughout the maritime world as the market leader in sterngear antifouling. This product is undoubtedly the best value sterngear antifouling on the market to date, and is the only widely available product which actively protects your sterngear in the most foul of waters guaranteed!

What makes Propshield so special?

Propshield has a lanolin base which is combined with a special combination of corrosion inhibitors which together provide protection from corrosion and prevent marine growth on all types of sterngear.

Its unique colour is derived from special additives which also help to repel barnacles. Since boats have had propellers, mariners have been trying to find ways of stopping barnacles sticking to them without very much success.

Now we have manufactured this new affordable product that significantly reduces/stops the adhesion of these creatures and significantly reduces/stops the effects of electrolysis and oxidisation as well.

The reason the barnacles can’t grow on your propellers is that Propshield is so slippery that they are unable to attach to the metal (or painted) surface. The product cannot be dissolved in water and even when the surface film degenerates over time the metal retains it within its pores, and so remains active.

As mentioned this product also helps to eliminate or at least reduce the effects of electrolysis so it stops your propellers dissolving into the water when your shore power is connected. If your propellers are green at the end of the season this is a sure sign that the copper is leaching out of the bronze through galvanic action.

This weakens the metal and blades can sometimes break off and penetrate the hull. At best the blade will loose efficiency and your fuel bills will increase as your vessel's top speed falls. Renewable resources Propshield Antifouling Grease is lanolin based which is a renewable resource.

Propshield is not based on oil or any other hydrocarbon like many other products are. Lanolin is a naturally occurring substance which is a by-product of wool production. It is not harmful to the sheep before or during its production or to humans during its application.
