Ceramic pad printing silicone

INSTRUCTION OF CERAMIC PAD PRINTING SILICONE RUBBER

Ceramic pad printing soft silicone belongs to RTV-2 liquid silicone material. It is white/yellow/red flowing state before curing, and its viscosity value is low, which is convenient for vacuuming and bubble release, and does not need to spend too much time on the defoaming process; silicone A and silicone B shall be mixed and stirred evenly according to the proportion, poured into the mold and wait for the rubber material to solidify at room temperature. The formed pad printing rubber transfer pads has good flexibility, and the original hardness is 16 shore A. If silicone oil is added according to the corresponding hardness, it can be softer; When printing ceramic products, the pad printing soft silicone rubber can completely rub the steel film pattern ink, and then transfer it to the ceramic products. The texture is clear, and the oil is better.

SELECTION OF SILICONE RUBBER FOR CERAMIC PAD PRINTING

According to the operation method, silicone rubber with hardness of 0 shore A to 40 shore A can be selected. In detail, it is:

Features of 0 shore A silicone to 20 shore A silicone hardness printing silicone rubber: it’s suitable for big product, deep product, and products with fine patterns.

Features of 20 shore A silicone to 40 shore A silicone hardness printing silicone rubber: it is used for products with simple patterns or flat surface.

REQUIREMENTS OF SILICONE PAD PRINTING RUBBER

① Silicone for ceramic printing shall have good operation function.

② Should not be so oily after adding much silicone oil

③ The smaller the shrinkage of silicone, the better.

④ Better tensile force .

⑤ The silicone pad can not be deformed.

⑥ High temperature resistance, more printing times, longer service life, better, acid and alkali resistance and aging resistance.
