A method is provided for applying a two-part RTV silicone tie coat directly onto damaged foul release coating area on a metallic substrate to enable restoration procedures. The direct application onto aged epoxy or silicone surface of an effective amount of an aminoalkyltrialkoxysilane, such as .gamma.-aminopropyltrimethoxy-silane, in a two-part RTV silicone tie coat, has been found to provide cohesive failure results with directly applied two-part RTV silicone top coat. A treated metallic substrate is obtained thereby.

Method of restoring damaged foul release coating area on a metallic

A coated article for foul release for use in aquatic applications does not require a discrete tie-layer to ensure adhesion of a coating to a substrate. An adhesion promoting layer comprising an anticorrosive material and a bonding agent is applied directly to the substrate. A release layer comprising organopolysiloxane is deposited onto the adhesion promoting layer. A method for applying the foul release coating comprises the following steps: applying an adhesion promoting layer, curing the adhesion promoting layer, applying the release layer and curing the release layer.

Foul release system

A novel apparatus for isolating solids or wetcakes from fluids is disclosed. Said apparatus is closed to the atmosphere and comprises a slip joint and a floating auger which allows for solid recovery under pressure in the absence of substantial solvent volatilization.

Apparatus for separating solids from fluids

A method is provided for making alkylhalosilanes by effecting reaction between an alkyl halide, such as methyl chloride and powdered silicon in the presence of a copper-zinc-tin catalyst. Significant improvements in reaction rate and product selectivity are achieved when copper is employed at a critical weight percent relative to silicon and critical weight ratios of tin and zinc are employed relative to copper.
