Abstract: Material having antifouling particles embedded in one surface is made by a transfer process. A sticky backing web is fed through a dip sticky side up. A charge of particles rolls in the dip, being unable to follow the web up a rise unless adhered to its surface in a layer. After coating the layer with a bonding agent a part cured elastomer sheet is brought into contact with the particles which are pressed into its surface, after which the backing web is stripped off to expose the particles.
