Most products for the tire industry are developed for application to green tires using any of the following systems:
Spray gun, either automated, e.g. Ilmberger or Plummer units etc., or hand-held spray guns.
Sponge or swab.
The actual application technique(s) chosen by any given tire plant depends primarily on the equipment available and the logistics of the particular plant. Experienced release agent suppliers should be able to provide recommendations to improve and optimize application techniques where desired.
