Wet Film Thick­ness Gages

Mea­sur­ing the film thick­ness of freshly applied coat­ings in the wet stage is very impor­tant. On one hand, film thick­ness influ­ences the qual­ity of a prod­uct; on the other hand, app­ly­ing too much coat­ing can be expen­sive. Depend­ing on the appli­ca­tion method, it is advis­able to mea­sure wet film thick­ness. For mea­sur­ing wet film thick­ness, BYK­Gard­ner offers a comb or \"inter­chem­i­cal gage\".

Comb Type Gage The comb is a ruler-shaped gage with two sup­ports at each of its six sides, hav­ing tabs of vary­ing lengths.

• Hexag­o­nal shape made of cor­ro­sion resis­tant stain­less steel

Pro­ce­dure:

• For mea­sur­ing, push the comb gage per­pen­dic­u­larly into the film using the mea­sur­ing range that cor­re­sponds to the expected film thick­ness
• Remove the comb gage from the coat­ing
• The wet film thick­ness will fall between the clear­ance of the short­est tab that is wet and the clear­ance of the next short­est dry tab
• The plas­tic comb gage may be used up to 60 °C (140 °F)
