Application Ratio

Silicone ink: 100g

Mixer(catalyst): 2~3g

Thinner: 300~500g

Processing

Here’s the routine for prepping your ink: grab a cleaning barrel and combine the base with 2–3% catalyst (that’s your 100/2-3 ratio) and mix it really well. Thin this down with 3 to 5 parts of thinner—use either White Gas or Dimethyl-benzene. Give it a good stir for about 5 to 10 minutes until it's smooth. Make sure you run it through a 300-mesh screen twice before it goes into the sprayer. Remember, once it's mixed, you’ve only got 12 hours to spray it, and try to keep the shop at a steady 22°C for best results.
