This epoxy comes in two colors, black and clear. The black epoxy will protect not only the PC board but your proprietary information as well. No one will be able to see your board under the black protective coating. The clear epoxy leaves your PC Board open to viewing but still protected from harmful moisture, impact, dirt, debris, chemicals and anything else that might damage your electrical components.
