3 NEW deconex Products Optical industry deconex OP 191 Solvent based detergent to remove solvent and alkaline based coulor markings on lenses in brush systems Metal industry deconex HT 1206 deconex OP 191 & OP 152 Mildly alkaline product for final cleaning on brass especially in the watch industry - similar to deconex HT 1207 deconex HT 1410 Alkaline detergent for the removal of polishing pastes especially in the watch industry deconex HT 1169 very versatile, removes oils, grease, polishing compounds, brightening effect on brass, copper and bronce deconex HT 1511 New corrosion protection as an ingredient in the formulation! Mainly use for (with tap water), hydrophobic, brighting effect

4 NEW deconex Products Metal industry deconex HT 1512 The product range in the field of metals required the renaming of the product name of previously deconex HardMetal Plus A deconex HardMetal Plus A Will remain until end of the year 2013 to allow switching the customers, afterwards archived! combination deconex HT 1170 deconex HT 1236 deconex HardMetal Plus B The old combination product = will be archived! Mildly alkaline degreasing agent and polishing paste remover for corrosion-sensitive metals, with corrosion inhibitor - Ideal product to combine with other detergents Corrosion inhibitor for cast iron, carbides and steel for use in final de-mineralized water rinse only 0,1 1% flammable, observe special information on use!

5 NEW deconex Developments Metal Industry released new products for testing in the industrial area deconex HT deconex HT deconex HT 1430.A Both detergents are in stage of R&D dedicated to the substrates in cutlery and knives for the removal of polishing pastes on aluminium substrates the best suitable product after trials with selected customers will remain in our product range Carbide grade, strong acidic product for tools and more fields of applications suitable NOTE In the future new products in the industrial area that are in the stage of development and have to be initially testet before they can be released, will be marked with the following syntax: deconex HT xyzw.a or.b etc.

6 NEW deconex Products Photovoltaic industry deconex PV 114 deconex PV 126 PV syntax: 100# = spray & brush; 200# = Ultrasonic Mildly alkaline, phosphate free detergent for PV substrate cleaning in spray, brush and ultrasonic application Mildly alkaline, phosphate free detergent for PV substrate cleaning in spray, brush and ultrasonic application especially Thin Film, saphire deconex PV 202 deconex PV 212 Highly alkaline, NaOH based dertergent for PV substrate cleaning in soaking baths and ultrasonic application Mildly alkaline, phosphate free detergent for PV substrate cleaning in soaking baths and ultrasonic application

7 Combinations of Products Optical industry deconex OP 191 & OP 152 Metal industry Solvent & alkaline based detergent combination to remove solvent and alkaline based colour markings on lenses in brush systems deconex HT 1400 & HT 1170 deconex HT 1400 & HT 1169 deconex HT 1401 & HT 1170 deconex HT 1401 & HT 1169 Highly alkaline product combinations for final cleaning before coating - especially on steel and HSS substrates Highly alkaline product combinations for final cleaning before coating - especially on brass, carbide and HSS substrates deconex HT 1512 & HT 1170 deconex HT 1512 & HT 1169 Alkaline product combinations for cleaning and degreasing - especially on aluminium substrates

11 DM Water System cleaning Task 1 alkaline cleaning Temp. max. 40 C deconex 20 NS, 1% & Hydrogen Peroxide, 1% - ciculate 60 min Task 2 rinsing Tap water - ciculate 15 min Task 3 neutralize deconex 25 Organacid, 0,1% in steps and portions until ph between 4-5 is reached - ciculate approx. 30 min Task 4 rinsing Demount filter inlets (not to be reused!) & rinse with tap water - ciculate 15 min Task 5 disinfection Hydrogen Peroxide, 0,1% - ciculate 60 min Task 6 final rinsing Demineralized water until ph 7 & conductivity level is reached - ciculate This procedure to produce clean DM-water in needed quality is recommended at least once a year, or every half year!

12 Borer Chemie - Support The technical demands of our customers tend to become more and more complex. Good solutions are only possible if they can be based on detailed and complete technical information!

13 Process Supervision Control the process parameters - Temperatures of tanks - Filling volume - Treatment durations - Function of pumps and filters - Oil separator - Ultrasonic

14 Process Supervision Control of the cleaning solution - Titration (Measurement of bath concentration) - Conductivity of the process tanks - Conductivity of the DI-water in the rinsing tanks - Particle monitoring - Control of the surface tension

15 TCI Technical Customer Inquiries What we need to know: Substrates Contaminations Existing cleaning plant/process Cleaning parameters Time Mechanics Detergents Temperature

16 TCI Fill-In the TCI COMPLETELY for either spray or ultrasonic Send information like - Actual cleaning process in detail - Operation prior-to-cleaning - Operation after cleaning Send sufficient number of substrates - Samples of each type of substrates - Originally contaminated - With data sheets of contaminants Describe actual problems with existing process. Describe the actual available cleaning equipment.

17 Don t forget.. cleaning means added value!
