Mixing Guide

IMG 20200806 133259  Take the A and B component of the same shore type and read the mixing instructions carefully.
IMG 20200806 133643  Weight and mix both component in a mixing container.
IMG 20200806 133821  If you want so coloured silicone, add some dye. Around two drops per 200g should be enough for a bright colour.
IMG 20200806 133952  To remove the bubbles, put the container into the vacuum-chamber and close the lid. Add some paper towels to prevent spillage.
IMG 20200806 133912  Close the left valve and open the right one (like shown in the picture) and turn on the vacuum pump. Do not go over -1 bar. When the desired vacuum is reached, close the right valve, wait till the bubbles have popped (slightly moving the chamber might help). Then open the left valve carfefully.
