Caltech Engineering Services- India offer precision stainless steel hexagonal hexagonal wet film comb. Hexagonal wet film thickness gauges are used for the quality control of wet film paint thickness measurements. These WFT gauges are supplied in micron / Thou Mill scales or dual micron. Wet film thickness gauges are also called as wet film comb. Wet film thickness gauges are available in different shapes (Square, Rectangular, Hexagonal, Octagonal). Stainless steel wet film gauges has excellent life, durability, long lasting and reusable.

Six sided hexagonal wet film comb are supplied in hexagonal size, giving 36 measurement steps on the comb, providing increased accuracy. Using a wet film comb perpendicular to and touching the substrate. Hold the comb in position and wait a few seconds until the teeth are wet. 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.

These wft gauges assist painting contractors, paint manufcaturing companies, and users to comply with the requirement of exact coating thickness over painted surface. Wet film thickness gauge control the coating process in wet coat of paint / primer. Excess / under coating is not permitted in view of drawbacks like cracking, excess coating thickness. Wet film thickness gauge can pre-determine coating thickness while it is wet condition. This being a destructive test, many users test wft gauge on the sample of rectangular panel, measure wet film thickness and control process parameters. Punched aluminum wet film thickness gauges or plastic WFT gauges are not preferred due to bending properties and low accuracy of the gauge, however they are economical and handy.

Caltech Engineering Services india manufactures stainless steel hexagonal wet film comb are made from quality steel with specially engraved surface markings have a wide measurement range with high-resolution with measurement, catering for virtually all of the standard wet film thickness measurement requirements.

Caltech Engineering Services India also supply disposable plastic WFT gauges for minimum use, simply place the wft gauge in the wet paint and note the wet paint thickness, Allow paint to dry and retain for future ISO record or customer requirements.

ISO 2808-7B, BS 3900-C5 method 7B, ASTM D4414-A specify that the wet film comb should be perpendicular to the substrate and the thickness of the coating should be stated as lying between the shortest wet tooth and the longest dry tooth
