PROCESSES FOR APPLYING LIQUIDS OR OTHER FLUENT MATERIALS TO SURFACES, IN GENERAL( apparatus for applying liquids or other fluent materials to surfaces B05B, B05C;
{
coating of foodstuffs A23P 1/084 , A23P 1/085
}
)
NOTE
-
This subclass covers:
- processes for applying liquids or other fluent materials to
a surface or part of a surface, in general, by any mechanical
or physical method and particularly processes producing
a uniform distribution of liquids or other fluent materials
on a surface;
- pretreatment of surfaces to which liquids or other fluent
materials are to be applied;
- after-treatment of applied coatings. Attention is drawn to the Note following the title of class B05.
