In order to ensure long term “absolute corrosion protection” to various substrates of critical equipment like vessels, scrubbers, ducts, pipes, pumps tanks, structures, equipment handling aggressive chemical & corrosive mediums, equipment exposed to humidity, steam, pollutants etc, ProCoat Specialities adopts stringent quality standards for surface preparation as well as coating application, to ensure a flawless coating system over structures to effectively resist corrosion phenomena. Step - 1: Surface contamination removal: In the above given corrosive environments, there are possibilities for deposition of alkaline, acidic or salt molecules over metal surface, which causes problem for adhesion of coating system. ProCoat adopts suitable methods for detecting presence of contamination by means of silver nitrate test / potassium ferricyanide test / litmus test etc. and adopts respective removal methods to ensure surface is free from contamination. If required chemical washing is done. Step - 2: Surface Cleaning: It is obvious that by using manual wire brush cleaning, corrosion / rust deposits cannot be removed completely and these left over ferrous oxide layer will be a problem in ensuring adhesion of coating system. ProCoat Specialities using an advanced method of surface cleaning by means of sand blasting / copper slag blasting / chilled iron grit blasting which is a process of cleaning metal with sand particles mixed with compressed air forced through nozzle and when directed to rusted surface it removes entire rust / corrosion deposits and virgin metal surface is exposed. This is called “Near White Metal Surface” as per Swedish standard SA2.5 finish. Blasting to an average surface roughness of 75 to 100 micron profile is highly effective in ensuring excellent bonding of ProCoat coating system. Step - 3: ProCoat coating application: Over the well prepared surface, ProCoat coating system will be applied initially by thin wetting coat with high hand pressure with the help of Roller / Tynex bristle brush to ensure complete wetting and covering the prepared surface. Once wetting is completed, second coat will be applied immediately to ensure recommended thickness of coating. Also, airless spray is used for coating. ProCoat coating systems are formulated with 100% solids. This means, there is no solvent in it and no addition of thinner while application. Since the coating is solvent free, wet film given over the surface will remain same even after complete curing without shrinking and loss of film thickness. ProCoat engineers are equipped with wet film gauges as well as dry film thickness gauges for checking during application. Step - 4: Coating Film Thickness Check: ProCoat Coatings being 100% solids, there will not be any kind of solvents in it which influence shrinkage of film on curing. Therefore the Wet Film Thickness and Dry Film Thickness remains same. Application engineers keep measuring Wet Film thickness by means of WFT gauge in order to comply the recommended thickness over the surface while application. Similarly, on full cure, ProCoat engineers do check the Dry Film Thickness with DFT gauge to have a cross check. Step - 5: Coating Integrity Check: Once ProCoat coating is fully dried, entire coated surface will be checked with an instrument called “Holiday Spark Tester”. By using this instrument, any manual or invisible micro pores over coating can be identified and marked for touch up works so that “a flawless coating can be achieved”. Fully applied and checked ProCoat coating system will act as barrier to aggressive chemicals and corrosive mediums ensuring complete isolation of metal surface so that equipment is protected for longer period without deterioration. Step - 6: Dual protection for Life enhancement: After completion of ProCoat coating system a weather resistant polyurethane coat is being applied based on necessity and request of customer to ensure resistance to UV rays so that ProCoat system will last longer for addressing corrosion problem. Note: The above is only a guideline. For example at times blasting is done multiple times if required.
