APPLICATIONS OF TROPICALISATION VARNISH SIL500
SIL500 can be sprayed or brushed. The thickness of the coating depends on the method of application.
SIL500 contains a UV trace which allows inspection of the PCB after coating to ensure complete and even coverage. The stonger the reflected light, the thicker the coating layer is.
Dispensing machine and spraying
SIL500 needs to be thinned with DVS before spraying. The optimum viscosity, to give coating quality and thickness, depends on the spray equipment and conditions but a starting point could be of 0.7 parts coating to 0.3 parts thinners. If the bulk coating material has been agitated, it should be allowed to stand until the air bubbles disperse. A higher dilution of SIL500 is not recommended because it can create some issues of curing and a tacky coating.
Ensure that the coating material has been agitated thoroughly and has been allowed to settle for at least two hours. The coating should be kept at ambient temperature. Gently apply the coating with a good quality brush (silk) to avoid leaving brush marks and not to disturb the components and wiring.
