                                           The ceramic pad printing silicon rubber

The ceramic pad printing silicon rubber is kind of liquid silicon rubber exclusively used for making ceramic silicon pad, which contains types as followings: 1. RTV-1 pad printing silicon rubber. 2. RTV-2 pad printing silicon rubber. The RTV-1 pad printing silicon rubber is also called addition cure RTV pad printing silicon rubber that contains only one liquid silicon rubber and could be cured as the ceramic pad after it is opened and added a little platinum catalyst. By comparison, RTV-2 pad printing silicon rubber contains two components, of which one is catalyst, and it could be cured only after the the main silicon rubber and the catalyst were mixed.

 
The ceramic pad printing silicon rubber

The usage of the ceramic pad printing silicon rubber: mainly used in pad printing for the pattern of the original product. Because the surface of most ceramic products is spherical, the ceramic pad printing silicon must have excellent limpness and extraordinarily pure silicon material without any impurity. The characteristics of ceramic pad printing silicon rubber: 1. fine and soft quality. 3. high purity and resilience. 4. high abrasion resistance. 5. no shrinkage. 6. good printing effect. 7. absorbing printing ink easily.
 

The types of ceramic pad printing silicon rubber(according to the hardness): hard silicon rubber and soft silicon rubber. Hard silicon rubber is the main ceramic pad printing silicon rubber, its hardness is around 30 degree, suitable for the pad printing of big-sized ceramic patterns but not applicable for ceramic patterns with spherical surface. For this type, the percentage of silicon oil should be 20%-60%, otherwise the silicone pad tends to be oily and not durable. By comparison, the hardness of soft silicon rubber is around 5-10 degree. And the soft silicon pad won’t appear to be oily and it is very durable, which will save the cost tremendously.
