Method of producing a layer of a vulcanized silicone rubber composition having an improved adhesion to the substrate surface
A method of producing a layer of a UV-cured silicone rubber composition on a substrate surface, including applying a primer composition to the substrate surface and hardening the primer composition followed by applying a UV-curable silicone rubber composition, and UV-curing the curable silicone rubber composition. At least one UV-sensitive crosslinking catalyst selected from compounds which initiate and promote curing of UV-curable silicone rubber compositions, is added to the silicone primer composition in any desired sequence before, during or after hardening of the silicone primer composition.
CYLINDER BORE HAVING VARIABLE COATING
Engine blocks and methods of forming the same are disclosed. The engine block may comprise a body including at least one cylindrical engine bore wall having a longitudinal axis and including a coating extending along the longitudinal axis and having a coating thickness. The coating may have a middle region and first and second end regions, and a plurality of pores may be dispersed within the coating thickness. The middle region may have a different average porosity than one or both of the end regions. The method may include spraying a first porosity coating in a middle longitudinal region of the bore and spraying a second porosity coating in one or more end regions of the bore. The first porosity may be greater than the second porosity and the first and second porosities may be formed during the spraying steps. The pores may act wells for lubricant.
METHOD FOR PRODUCING A MULTICOAT PAINT SYSTEM BY POSTADDITIZATION OF AT LEAST ONE BASECOAT WITH AN AQUEOUS DISPERSION COMPRISING POLYAMIDES AND/OR AMIDE WAXES
