The Printed Circuit Board in electronic Devices and facilities attract dust by static electricity.This Static electricity leads to the PCB, which short-circuits the degradation of performance, and shortens service lifespan. NWK-99 is newly invented product to keep electronic devices and facilities from those possible risks and dangers. NWK-99 blocks dust from coming into the PCBs, preventing unwanted losses and accidents.NWK-99 blasts away oil, dirt, flux residue and condensation from sensitive electronics and electrical equipment with pinpoint precision. It dries quickly, leaves no residue and removes more dirt than leading competitors, making it the best at cleaning electrical contacts. Safe to use and 50-state VOC compliant, it’s ideal for use on printed circuit boards, controls, switches, precision instruments, and electric panels.
