APPLICATIONS OF TROPICALISATION VARNISH SIL250
SIL250 can be sprayed or brushed. The thickness of the coating depends on the method of application.
SIL250 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
SIL250 can be applied with a jetter.
SIL250 is suitable both for use in manual spray guns and computer controlled airless spray equipment that only coats the required areas of the PCB, eliminating the need for masking. The nozzle of the spray gun requires to be selected to give an even spray to suit the prevailing viscosity of the coating material.
To ensure penetration of the coating beneath the components and in confined spaces, spray the assembly from all directions to give an even coating.
