CRC/Barcode Name Pack Size
Aerosol 300 g 6

CRC Plasticote 70 is a clear acrylic lacquer ideal for the protection and insulation of printed circuit boards and electronic parts.

It forms a flexible, clear film that protects printed circuit boards from current creepage and short circuits and is resistant to environmental effects such as moisture, salt spray, atmospheric oils, dust, oxidation, diluted acids, alkalis, alcohol and humidity.

Three coats will provide a dielectric resistance of 16kV. Allow 30 minutes drying time between coats to facilitate build up.

The containing UV indicator allows for instant quality control of the applied coating.

CRC Plasticote 70 is effective in a wide temperature range, the protective film softens only at 100°C. It readily endures temperatures down to -70°C, provided the film is not subjected to mechanical stress.

CRC Plasticote 70 is also suitable for protecting maps, charts, legal documents and drawings from water.
