Turbo-Coat Acrylic Conformal Coating

In almost all cases, the cloudy or milky cure comes from coating in higher humidity conditions. The white foam (from an aerosol) is caused the same way. We have the following suggestions: 1) If possible, allow the substrate and coating material to come to approximately the same temperature when applying. 2) Avoid applications in RH > 60%. High humidity ranges will discolor some coating resins and will start curing others. Besides the aesthetic value, it certainly may affect adhesion to the material. 3) Specifically on the silicone coating, if the resulting application is foamy, increase the focal point of the can, ie back off to about 10 -12” from the substrate & make 2 -3 light passes rather than one heavy pass to coat the board.

Wet film thickness = Sq. ft. per gal. | 0.1 mil = 16,040 | 0.5 mil = 3,210 | 1 mil = 1,600 | 2 mil = 802 | 3 mil = 535 | 4 mil = 401 | 5 mil = 321 | 6 mil = 267 | 7 mil = 229 | 8 mil = 201 | 9 mil = 178 | 10 mil = 160

Metal 5-gallon and 55-gallon drums are compatible with standard 3/4" and 2" spouts. Ideally use 3/4" for 5-gallon, 2" for 55-gallon.

I suggest you get into the habit of clearing the valve after every use. You turn the can upside-down and spray until it only sprays propellant. If you don’t do that, you run the risk of dried coating building up in the valve or actuator button. If in the button, you can switch it for another one and it should work. If in the valve, there may not be much you can do to save the can.

The shelf life of a product can be found on either the technical data sheet (TDS), available on the product page, or by looking on the certificate on conformance (COC). The COC can be downloaded by going to https://www.techspray.com/coc. Once you have the shelf life, you will need to add it to the manufacture date for a use-by date. The manufacture date can be identified by the batch number. The batch code used on most of our products are manufacture dates in the Julian Date format. The format is YYDDD, where YY = year, DDD = day. For example, 19200 translates to the 200th day of 2019, or July 19, 2019. This webpage explains and provides charts to help interpret our batch numbers: https://www.techspray.com/batch-codes.
