Aluminum Hexagonal Wet Film Comb Coating Thickness Gauge 3000um (120mils)

Specifications

Measuring coatings before they have cured can predict the final film thickness.

Applying too much coating not only wastes time and materials, it can also affect the performance and finish of the product. Too much wet film can cause the coating to crack as it cures; too little coating increases the risk that the substrate will not be sufficiently protected, leading to rust spots.

These hexagonal precision formed stainless steel wet film combs are long lasting and reusable and are supplied in a range of thicknesses measuring up to 3000µm (120mils).These six sided combs vary in size, giving either 24 or 36 measurement steps, depending on the comb, providing increased accuracy.

These punched aluminium combs offer the user a low cost method of measuring the wet film thickness.

The Elcometer 112AL, being punched from aluminium, is not as accurate as precision formed, stainless steel wet film combs and has a shorter lifespan.

Supplied in a pack of 10 combs, they have Metric units (25 - 3000µm) on one side and Imperial values (1 - 118mils) on the other.

USING A WET FILM COMB

1) Place a comb perpendicular to and touching the substrate.
2) Hold the comb in position and wait a few seconds until the teeth are wet.
3) Remove the comb from the film. The wet film thickness lies between the biggest value
‘coated’ or ‘wet’ tooth and the smallest value ‘uncoated’ or ‘dry’ tooth.
