Liquiguard Technologies announces Liquiguardwconformal coating for the electronic and electrical industry
Liquiguard Technologies is pleased to announce Liquiguard® its unprecedented conformal coating developed to protect electronic devices and printed circuit assemblies from damage when exposed to moisture, water, beverages, non-corrosive liquids and even mild solvents.
More than a moisture repelant, Liquiguard is the only coating that will continue to protect a powered up electronic device in case the device accidentally becomes fully immersed in water or other non-corrosive liquid. Liquiguard bonds tenaciously with the PC board and its components. Its ability to safeguard the PCB with a 1 mil film has the added advantage of heat dissipation and ease of repair without prior removal of the coating. Owing to its very good weathering and aging properties, Liquiguard can also be used to protect electrical assemblies exposed to the elements.
Liquiguard is manufactured in the USA and sold in aerosol cans, pint, quart, gallon, five gallon and 50 gallon packing. It can be applied via dipping, spraying or brushing. Liquiguard is a water-based non-toxic, non-hazardous and environmentally safe product.
