The rubber base is processed with 3 wt% Catalyst T 12 and reaches a very low Shore A hardness of 11 with a light gray final color. The low mixed viscosity of 13,000 mPa·s ensures excellent flowability and self-deaeration. Its distinguishing feature is the antistatic finish, which rapidly dissipates static charge from the surface of the printing pad. With a working time of approximately 75 minutes and a curing time of 5 hours at room temperature, this is a reliable system for producing antistatic pads for industrial pad printing.\u003c\/p\u003e\n\u003ch3\u003eKey Benefits\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cstrong\u003eVery soft Shore A 11:\u003c\/strong\u003e – an exceptionally supple rubber that delivers optimal ink transfer in pad printing on irregular and complex surfaces.\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eMixed viscosity 13,000 mPa·s:\u003c\/strong\u003e – very good flowability and self-deaeration, flowing effortlessly into fine mold details.\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eAntistatic finish:\u003c\/strong\u003e – rapid dissipation of static charge, essential when printing sensitive electronic components such as CPUs.\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003ePot life approx. 75 minutes at 23°C:\u003c\/strong\u003e – ample working time for careful pouring, even with larger printing pads.\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eTear strength \u0026gt; 3 N\/mm:\u003c\/strong\u003e – resistant to mechanical stress during repeated use of the pad.\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eAdjustable hardness with AK 35:\u003c\/strong\u003e – adding Wacker Silicone Fluid AK 35 lowers the Shore A hardness for even softer printing pads.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eTypical Applications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eProduction of antistatic printing pads (tampons) for industrial pad printing.\u003c\/li\u003e\n\u003cli\u003ePrinting sensitive electronic components such as CPUs, switches and sensors.\u003c\/li\u003e\n\u003cli\u003ePrinting keyboards, control panels and displays.\u003c\/li\u003e\n\u003cli\u003ePrinting toys, sporting goods and plastic automotive parts.\u003c\/li\u003e\n\u003cli\u003ePrinting porcelain, promotional items and other irregular surfaces.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eProcessing Instructions\u003c\/h3\u003e\n\u003col\u003e\n\u003cli\u003eStir the rubber base (component A) thoroughly in its container to evenly distribute any settled fillers.\u003c\/li\u003e\n\u003cli\u003eWeigh out 3 wt% Catalyst T 12 based on the total mass (rubber base, or base plus silicone fluid).

The supplied Catalyst T 12, however, contains a tetraorganotin compound, is flammable (flash point \u0026gt; 50°C) and may cause irritation to eyes and skin on contact. When processing the catalyst, wear protective gloves and eye protection, ensure adequate ventilation and store the catalyst under lock.
