Neutralizer and De-fluxing Cleaner (Super Concentrate) EnviroSense’s product Enviro Gold #817 is an organic aqueous chemistry. The product provides an alternative to CFC’s and other types of solvents currently being used in various cleaning tasks. Enviro Gold is designed to remove RMA/RA, WS/OA paste/flux residues and to reduce or eliminate other common ionic and non-ionic contaminants. The #817 not only cleans Printed Circuit Boards, it is an excellent stencil cleaner and product for removing process residues in precision metal cleaning. The Enviro Gold chemistry utilizes a new generation of surfactants that allows it to meet circuit assembly or precision metal cleaning challenges. Enviro Gold is environmentally sound, user friendly and satisfies workplace safety issues while still producing a desired level of cleaning. USE DIRECTIONS (BATCH): This aqueous based formula is in a highly concentrated form. Depending upon the application requirements, Enviro * Gold is designed to be mixed with de-ionized water at a 9 to 1 dilution ratio (10%) at a temperature of 145°F for the removal of RA/RMA or LS/No-Clean flux residues. For WS/OA and HASL (PCB) flux use at 3 to 5% of chemistry, by volume, at 140°F to 150°F. These suggested dilution ratios may vary due to soldering profiles, rosin content of flux and residue/contaminant removal requirements. A "Bench Test" is recommended to determine proper dilution, temperature, dwell and material compatibility. For Post HASL cleaning; PCB panel should be in contact with the #817 chemistry for a minimum of 20 seconds. USE DIRECTIONS (ULTRASONIC): For removal of RA/RMA’s we suggest testing begin at 120°F, with a dilution ratio of 1 part "Enviro * Gold" to 14 parts de-ionized water (approx: 7%) ; 5 minute wash cycle. USE DIRECTIONS (BATCH/INLINE): For removal of RA/RMA’s we suggest testing begin at 145°F, with a dilution ratio of 1 part "Enviro * Gold" to 12 parts de-ionized water (approx. 8%); 1 minute to 5 minute wash dwell. If cooler than 140°F higher concentrations may be necessary. Some of the Enviro Gold #817’s key characteristics are: Alkaline, water based cleaner and neutralizer for dissolving fluxes and cleaning other board or assembly contaminants. Moderate pH to inhibit solder joints from dulling. Is non-corrosive and ships no-regulated. Flash point: none to boiling at suggested operating concentrations. Designed for use at lower temperatures to minimize operating costs and maximize safety. Made without, nor contains any phosphates, ozone depleting chemicals, ethylene glycol ethers or heavy metal chelators like ’E.D.T.A.’, and citrate. All compounds in this chemistry are biodegradable in the P.O.T.W. Base compound (MEA) is on the U.S.E.P.A.’s Preferred Alternative List. Excellent de-foaming characteristics, especially in WS/OA cleaning systems. Does not contain isopropyl alcohol. Low Odor. Extremely low Volatile Organic Compounds. Formulated with a surface tension reducing agent and surfactants that allow the product to penetrate under tight geometries to clean and rinse, residue free. Compatible with most process and equipment materials. After proper metal particle filtration and pH adjustment, spent effluent can go to sanitary drain. Can be used in ultrasonic, batch, submersion and inline cleaning systems. Available in either five or fifty-five gallon containers.
