Do NOT allow to enter gutters, waterways. Always check and comply with local and state regulations. Dispose of residue wrapped up in newspaper, then into plastic bags, then into garbage service or an approved chemical treatment facility. Common Washing up Sink or Sewerage disposal once the solution is completely exhausted (very dark blue) and then rinsed with an abundance of tap water. The pH of this material will not/cannot cause any effect to sewerage pipes. RCS Comment : Do NOT DUMP, that is a waste of chemicals and money, always pour it back into large seal-able plastic containers, use and re-use. Our own solution is many years old, and it still works with just adding a small amount of fresh developer. If the solution is poured back into containers via a filter and funnel then the 'DEVELOPER SOLUTION' will last many months before a complete change is ever needed, then it should be newspaper soaked then safely put away. Use filter to remove the undisolved 'RISTON' flakes. I personally do recommend a monthly 'stocking' filter so as to remove the larger 'undisolved' flakes of RISTON, rather that weaken the developer. ___________________________________________________________________________ 15.

Obviously this is a 'chemical' used in industry for dissolving BLUE 'AE' RISTON that has NOT been UV hardened. I have NOT heard EVER of any comment to the detriment of this product. Common-sense must surely be a requirement for working in this industry and this product should NOT be DRUNK or THROWN at anybody, not considering the safety angle but please consider the wasteful cost at having to re-purchase new solutions because of some ones irresponsible actions. The use of this material in a totally sealed room is a warning NOT to DO, and owing to the general movements of industry, a totally sealed room is not a usually seen item in the common work flow of a normal 'these-days' production. If any solution gets on your hands during the process, then at conclusion of day, wash/rinse hands, dry, and use any BARRIER - LANOLIN Moisture CREAM This 'solution' controls the pH from 'drift' and over the past 25+ years I have even noticed a 'pH drift' change in normal drinking tap water from capital city to another, not even considering the city - country variance, with the end result the 'development' is a careful EXACT control of pH. If the 'drift' cannot be controlled then even a transfer of a wet circuit board to another simple drinking tap water, can falsely trigger the board surface of the 'exposed' hardened tracks/pads and you will see them rinse off the circuit board and disappear down the drain. So do not wash the exposed/developed circuit board, just simply PAD dry next for DALO finish. The above MSDS warnings are based on a RAW Concentrated Solution 20 x this actual 'working' solution and NOT available for general public sale & use. CEO RCS Radio - Robert J. Barnes (Bob) ___________________________________________________________________________ 18. HOW to Use this SOLUTION The 'solution' you first get is the 600ml bottle and it is DOUBLE STRENGTH for normal development process of RISTON AE 'Aqueous Experimenter' process So firstly look around for an older empty 1.25litre plastic bottle, wash any labels off, and CLEARLY MARK it that it is NEGATIVE RISTON DEVELOPER and that it will be now the WORKING SOLUTION to use and re-use. Wash out thoroughly any old solution from the bottle, and pour into the now empty 1.25 litre bottle the entire contents of a new 600ml Riston Developer then add plain ordinary tap water up to the part neck, that is you will add approx 600ml common tap water, agitate, invert and do a reasonable mix. An area deemed UV safe is if NO SUNLIGHT, NO WHITE FLURORESENT TUBES, safe illumination is the humble 25w common light bulb (or a 40w with a dimmer) This is the ONLY illumination permitted in handling 'un-exposed' RISTON AE Copper Clad Fibreglass circuit board prior to a controlled UV Exposure. Then expose width UV Light (350 Angstrom) or raft of 20w fluro tubes about 3" (75mm) away from the 'sandwich' of Riston coated copper laminate, in ever close contact to the Negative, compression fit either vacumm pump, or alligator clips to obtain max pressure, then expose for certain time. In industry, a raft of fluro's are approx 30-60sec and depending on thinner tracks (around 10thou may need more), but note that a 3kW UV lamp that we normally use, is only 5 to 6 seconds. What we are doing here is a simple contact 'exposure' , a procedure done in ordinary darkroom photography for a zillion years. It is at this point 'protective' goggles are more than a smart thing to do (even if is a O.H. & S. LAW ) as any etching solution is hazardous to eyes. Right, Expose, then pull OFF the thin 1 thou 'oxygen protector', discard correctly and place the now exposed Riston exposed blank into the plastic tray, (you may now see a faint trace of 'hardened' darker blue track/pads) then using either a 'brush', or 'gloves' with a well used 'scotch brite' and gently rotate and wash away the unwanted RISTON , until the area that you want to be etched away, shows up as shiny new pre-scrubbed copper. PAD Dry, DO NOT FRESH RINSE/WASH as the variant of pH from the solution to your local tap water may (will) trigger the exposed hardened Riston image, and so simply use an old 'paper towel' Touch PAD dry, again still in a UV prohibited area, using humble simple light, with low wattage light bulbs. The Board is now dry, so with an ARTISTIC touch, use a DALO Pen to add or repair any tracks that look a bit 'thin' and also use a sharp Exacto #6 small hobby knife, and scrape away any excess DALO, or 'smeared' tracks. In general, prepare the board ready for etching, because at this stage, it is the final 'human touch' before etching, this is the point of NO return. Your board can be etched in a few solutions, many of the hobbiests use Ammonium Persulphate, which is a 'clean' etch, with clothing spills not to savagely attacked by your mother (or wife) 'clothes washer' etc. Ammonium Persulphate or 'amminiacal' or UE50 meaning Ultra Etch 50'c is prewarmed in a plastic dish and the warmth of the etchant will remove the exposed shown copper, but remember rock, agitate so as the copper area to be etched away is continually getting awashed by fresh etching solution. Ammonium Persulphate is commonly used in schools as well as bigger circuit production board factories where Plated Through Holes are chemically fitted Another etching solution (we at RCS and others use) is Ferric Chloride, it has the distinct advantage that ambient Temperature is NOT that important, from 20'c to 40'c is quite ok, with the reality that a higher temp, will etch quicker, but watch the progress closely. This product is not liked by those who do your washing, as it does create little 'orange' rust spots on your clothing and hands, it does 'stain'. The stain can be removed but according to O.H. & S. and the Geneva Convention, one should not be caught using this product for a few reasons, all true, if in incompetent hands. The board is now clearly etched, showing Proud 'blue' Riston Tracks/Pads and bare exposed fibreglass, now wash, rinse dry, then put the dry board into the STRIPPER Solution - that is another story. The circuit board coating and etching process was invented in England back in 1943 primarily by a 2 chappies, one called Paul Eisler and chemist Shaun McGovern, the actual chemicals as first used after 'pitch' and acid, leading up to acid resisting inks and use of Ferric Chloride. A procedure that only a few in the world know is how to regenerate the used Ferric Chloride solution and that way, production quantities are not needed to be re-purchased monthly, and there is NO WASTE solution for disposal as well as separating the 'scrap' copper out of solution into small 'ingots'.
