GoldenRatio is the symbol representing the golden ratio, a constant that gives the limiting value of the ratios of successive Fibonacci numbers as well as the value of the "simplest" possible continued fraction.Available in either five or fifty-five gallon containers.Can be used in ultrasonic, batch, submersion and inline cleaning systems.After proper metal particle filtration and pH adjustment, spent effluent can go to sanitary drain.Compatible with most process and equipment materials.Formulated with a surface tension reducing agent and surfactants that allow the product to penetrate under tight geometries to clean and rinse, residue free.Extremely low Volatile Organic Compounds.Excellent de-foaming characteristics, especially in WS/OA cleaning systems.Base compound (MEA) is on the U.S.E.P.A.'s Preferred Alternative List.All compounds in this chemistry are biodegradable in the P.O.T.W.Made without, nor contains any phosphates, ozone depleting chemicals, ethylene glycol ethers or heavy metal chelators like 'E.D.T.A.', and citrate.Designed for use at lower temperatures to minimize operating costs and maximize safety.Flash point: none to boiling at suggested operating concentrations.Is non-corrosive and ships no-regulated.Moderate pH to inhibit solder joints from dulling.Alkaline, water based cleaner and neutralizer for dissolving fluxes and cleaning other board or assembly contaminants.Some of the EnviroGold #817C's key characteristics are: If cooler than 140☏ higher concentrations may be necessary. For Post HASL cleaning PCB panel should be in contact with the #817C chemistry for a minimum of 20 seconds.įor removal of RA/RMA's we suggest testing begin at 120☏, with a dilution ratio of 1 part "EnviroGold" to 14 parts de-ionized water (approx: 7%) 5 minute wash cycle.įor removal of RA/RMA's we suggest testing begin at 145☏, with a dilution ratio of 1 part "EnviroGold" to 12 parts de-ionized water (approx. A "Bench Test" is recommended to determine proper dilution, temperature, dwell and material compatibility. These suggested dilution ratios may vary due to soldering profiles, rosin content of flux and residue/contaminant removal requirements. For WS/OA and HASL (PCB) flux use at 3 to 5% of chemistry, by volume, at 140☏ to 150☏. Depending upon the application requirements, EnviroGold is designed to be mixed with de-ionized water at a 9 to 1 dilution ratio (10%) at a temperature of 145☏ to 165☏ for the removal of RA/RMA or LS/No-Clean flux residues. This aqueous based formula is in a highly concentrated form. EnviroGold is environmentally sound, user friendly and satisfies workplace safety issues while still producing a desired level of cleaning. The EnviroGold chemistry utilizes a new generation of surfactants that allows it to meet circuit assembly or precision metal cleaning challenges. The #817C not only cleans Printed Circuit Boards, it is an excellent stencil cleaner and product for removing process residues in precision metal cleaning. EnviroGold is designed to remove RMA/RA, WS/OA paste/flux residues and to reduce or eliminate other common ionic and non-ionic contaminants. The product provides an alternative to HCFC's and other types of solvents currently being used in various cleaning tasks. #817/49.10-5008C - Saponifier - Neutralizer and De-fluxing Cleaner (Super Concentrate)ĮnviroSense's product EnviroGold #817/49.10-5008C is an organic aqueous chemistry.
