Abstract: An antifouling coating formulation includes a first part making up the matrix of the coating. The first part is a silicone-modified titanium silicate glass. A second part of the formulation serves to prevent barnacles and other organisms from attaching to the coating and includes a combination of liquid polymers, oils, or liquid waxes which are incompatible and will phase separate after the mixing. The materials have a chemically reactive group which serve to graft the materials into the matrix. An optional third part of the formulation includes a compound which prevents or inhibits slime formation.
