Protektor® Conformal Coating is a fast-drying, single-component acrylic (resin) conformal coating for PCBs and electronic assemblies — a protective coating that shields printed circuit boards from moisture, corrosion, dust, fungus, caustic vapours, thermal shock, dielectric stress and chemical attack. A trusted PCB coating / PCB conformal coating for electronics, telecom, automotive, defence and aerospace manufacturing.
Its high dielectric strength prevents high-voltage arcing and the corona effect, while the protective film insulates and protects the electrical and electronic components. It conforms to IPC-CC-830B / Military-Grade MIL-I-46058C, is approved by the Centre for Development of Telematics (C-DOT), and is RoHS compliant and environment friendly.
