Liquiguard Technologies Announces Liquiguard(R), Conformal Coating For the Electronic and Electrical Industry.FORT LAUDERDALE Fort Lauderdale (lô`dərdāl), residential, commercial, and resort city (1990 pop. 149,377), seat of Broward co., SE Fla., on the Atlantic coast; settled around a fort built (c.1837) in the Seminole War, inc. 1911. , Fla. -- Liquiguard Technologies is pleased to announce Liquiguard[R], its unprecedented conformal coating Conformal coating material is applied to electronic circuitry to act as protection against moisture, dust, chemicals, and temperature extremes that if uncoated (non-protected) could result in a complete failure of the electronic system. 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 repellant, 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 PCB: see polychlorinated biphenyl. PCB in full polychlorinated biphenyl Any of a class of highly stable organic compounds prepared by the reaction of chlorine with biphenyl, a two-ring compound. with a 1 mil film has the added advantage of heat dissipation and ease of repair without prior removal of the coating. Due 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 fifty gallon packing. It can be applied via dipping, spraying or brushing. Liquiguard is a water based non-toxic, non hazardous and environmentally safe product. Electrical Properties: (Certified results provided by Pacific Testing Laboratories, CA) Insulation Resistance, per IPC-TM-650, Method 2.6.3 1x1011 (after humidity cycling) Dielectric Withstanding Voltage: ML-PRF-55110G, paragraph A.3.7.5.3 and A.4.8.5.3 > 1200V/mil Dielectric Strength test method ASTM ASTM abbr. American Society for Testing and Materials D-49, breakdown voltage KVAC, RMS average 1200V/mil at 0.0008 inch thickness Dielectric constant, per ASTM D-150, at 1 MHz (MegaHertZ) One million cycles per second. It is used to measure the transmission speed of electronic devices, including channels, buses and the computer's internal clock. A one-megahertz clock (1 MHz) means some number of bits (16, 32, 64, etc. and 250[deg]C, 2.88 Dissipation Factor, per ASTM D-150, at 1MHz and 250[deg]C, 0.040 Volume Resistivity resistivity Electrical resistance of a conductor of unit cross-sectional area and unit length. The resistivity of a conductor depends on its composition and its temperature. ASTM D-257 at 0.0008 inch thickness 1.6x1011 |
