Abstract

Abstract A covering material for underwater objects such as boat hulls or water intake pipes. The covering includes a waterproof coating such as adhesive or paint containing capsicum derivatives such as cayenne pepper or oleoresin capsicum, with the coating applied to the outer surface of the object to be protected, to repel marine organisms which might otherwise attach themselves to the object. In some applications copper material may also be applied to the coating.

Claim 12
Dependent Claim 124 words
An anti-fouling covering for preventing the growth of marine organisms on the exterior of submerged objects comprising: (A) a waterproof adhesive layer including cayenne pepper material having the property of being repellent to marine organisms, said layer covering the surface to be protected when submerged underwater; and (B) a permeable layer of copper containing material attached to the outer surface of the adhesive layer and retained thereby on the surface to be protected; (C) the permeable layer being of such a configuration as to leave certain areas of the outer surface of the adhesive layer exposed to the ambient environment of the submerged object through open portions of the permeable layer; (D) said permeable layer having the property of being repellent to marine organisms.
Claim 13
Dependent Claim 33 words
An anti-fouling covering as claimed in claim 10 wherein the cayenne pepper material in the waterproof adhesive layer is a particulate material at least partly embedded therein and lying beneath the permeable layer.
Claim 14
Dependent Claim 48 words
An anti-fouling covering as claimed in claim 11 wherein the repellent properties of the cayenne pepper material react through interstices of the permeable layer in combination with the repellent properties of the permeable layer to intensify the hostile environment for marine organisms on the surface to be protected.
Claim 15
Dependent Claim 33 words
An anti-fouling covering as claimed in claim 10 wherein the permeable layer is at least partly imbedded in the waterproof adhesive layer and the adhesive layer extends into interstices in the permeable layer.
