RTV silicone rubber for pad printing for printing irregular patterns is mainly use for printing irregular patterns of plastic toys, electroplating toys and trade makers. Pad printing silicone rubber as a carrier which transfers patterns on the steel plate to the toys products surface.
RTV silicone rubber for pad printing for printing irregular patterns has the advantages of abrasion resistance, high temperature resistance, good printing effect, etc. , which made of top-quality raw material due to adding American Dupont Teflon high-temperature resistance new material, is processed through high-temperature machining.

Part A: an non-toxic and odorless liquid in translucent color with platinum inside

Why RTV silicone rubber for pad printing for printing irregular patterns is incomplete or not clear?
(1) If the silicon pad is too hard while the pattern is very delicate or small, the printing patterns will be incomplete or not very clear, for in that way the silicon pad could not adsorb the printing ink from the steel plate well. If your pattern is very delicate or small, please use soft silicon pad for pad printing.
(2) If the percentage of water in the ink is very high, the printing pattern also will be incomplete, and spot may appeared. For this situation, please clean your ink box, or change the printing ink or Tianna water.
