10 mil / 160
Q. Conformal coating: The "stock" products are too viscous for some applications. Are there other viscosity ranges offered or could the origional product be diluted to the appropriate range?
A. Techspray offers "thinner" viscosity ranges as custom blends. However, each of the 3 types of coatings in bulk may be thinned with 2105.
Q. Conformal coating: When using conformal coatings in general, what causes a "milky" sure or white "foam" on the substrate?
A. 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. Techspray has the following suggestions:
1. If possibly, allow the substrate and coating material to come to approximately the same temperature when applying.
2. Avoid applications in RH > 60 percent. 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 inches from the substrate and make 2-3 light passes rather than one heavy pass to coat the board.
