Cota Marksolid 904 User Manual Marks Black on Anodised Aluminium Important to know gt The product is a thixotrope therefore shake well before use for at least for 1 minute Shaking will cause a change in consistency the product will then become a more fluid consistency To dilute the product only use distilled water and never bring it in touch with alcohol Apply too thick a coating should be avoided For some laser marking machines it is necessary to defocus them for good results How to proceed 4 Make sure the Anodised Aluminium is clean dry and free from grease When indicated clean with alcohol or acetone The product must be shaken thoroughly for at least one minute Don t stop Shaking earlier even if the product already seems to be liquid continue shaking The product shows thixotrope characteristics As a result of longer storage periods the consistency changes to a viscous gel Only if the product is shaken the gel changes back to a liquid condition The product s viscosity decreases by shaking for a longer period The longer you shake the product the more liquid it will get Shake for approx 1 minute at least Before you start to dilute the product further make sure you have shaked long enough For dilution only use distilled water Never add alcohol as a diluting agent Adding alcohol will render the product unusable To apply the product use a foam brush Make sure the brush
3. is completely dry A brush which is still wet from cleaning would dilute the product more This would result in irregular markings You will receive the best results with the provided foam brush only with sample kit while using the undiluted product Dip the brush approx 5 mm deep into the liquid product Lead the brush slowly and with constant speed smoothly over the surface without stopping Repeat this as often as necessary to coat bigger areas with several lines one below the other To coat the surface arrange it ina gt 45 angle Then excess liquid product will flow to the bottom of the line and can be taken away by the brush when producing the next line 5 6 A smooth and dark mark you should increase the marking speed step by step until the colour of the mark fades out to grey The picture shows a good result gt 9 O Celta Apply product by using an Airgun or Airbrush Try to find an adjustment for your spraying equipment to avoid the need for diluting the product too much Higher dilution may cause trouble with the adhesion on the anodised surface Droplets would be produced and a poor marking result would be delivered The coating thickness should be 30 um and just cover the surface It shouldn t exceed 30 um Nevertheless a too thin coating produces a grey instead of a black mark Approach to adjust and optimise laser parameters Make sure the coating is dry before you start with laser marking Start with high
