Antistatic silicone elastomers for pad printing

The antistatic silicone elastomers developed by the CHT Group are composed of electrically conductive silicone polymers and various special fillers. The RTV 2 silicone elastomers are perfectly suited for producing high quality printing pads.

The great variety of different Shore hardnesses and the high moulding accuracy promote a safe, high quality printing process on versatile common materials:

  • Porcelain
  • All types of synthetic materials
  • Electrical devices

The outstanding release properties of the silicones from organic and inorganic surfaces are particularly advantageous. Finest detail reproduction is facilitated by the excellent transfer property of the printing ink in pad printing.

The silicone elastomers of the CHT Group have additionally an outstanding mechanical and chemical stability.


Electrostatic Charge

In pad printing it is important that a clear, reproductive print with defined outlines and complete colour fill is achieved. Static charges may affect the print appearance in various ways.

The antistatic properties of our silicone elastomers help prevent the following undesired effects:

  • Adhesion of dust and soilings on the pads
  • Ink splashes and a blurred print appearance
  • Static discharge shock during printing

Advantages of our silicone elastomers:

  • Antistatic properties
  • High transfer capacity
  • Good tear strength
  • Very good stability to chemicals
  • Very good mechanical properties
  • Excellent release properties
  • Various Shore hardnesses
  • Simple handling
