Excellence in printing quality and performances



For manufacturing of silicone printing pads TERRA offers a special range which consists of RTV-2 silicone rubberssilicone fluids and colorants for silicone rubbers.


SILASTOSIL®  PP line pad printing silicone rubbers are flowable, two-component room-temperature-vulcanizing RTV-2 silicone rubbers and help manufacturers to formulate a range of printing pads with an unlimited variety in softness, surface characteristics and color. They are characterized by their outstanding properties which make them indispensable for producing print pads:


- low viscosity

- very good flowability

- good self-deaeration (no air bubbles)

- high reactivity for fast demolding even if large amount of silicone fluid is added

- fast thick section cure at room temperature 

- if required the product cure can be heat accelerated 

- low or medium hardness alternatives (14 or 30 shore A)

- high potential of silicone fluid adding

- high resistance to high temperature and aging (resist -60 to 250°C)

- long-term stability of mechanical properties

- very low shrinkage, good dimensional stability

- excellent tear resistance

- long servive life

- very precise ink transfer

- suitable for many types of ink

- clear printing pattern (no impurities, no particles)


Depending on the shape and fragility of the objects to be printed, printing pads need to have a specific hardness. To reduce the hardness, some amount of silicone fluid can be added into the silicone rubber. TERRAFLUID® line silicone fluids are ideal to reduce the hardness of silicone rubbers. They are cost-effective, and they do not affect the printing quality of printing pads.


Color coding of silicone printing pads is sometimes desired. Holcosil® line liquid colorants for silicone rubbers (flowable pigment pastes) provided by TERRA are particularly well suited to color SILASTOSIL® PP line pad printing silicone rubbers. Additions of 1-2% by weight are enough to color the pads.
