Liquid Pad Printing Silicone Rubber Material
1. Applications of liquid pad printing silicone rubber
Pad printing silicone rubber is mainly use for printing irregular patterns of plastic toys, electroplating toys and trade makers . Pad printing silicone rubber as a carrier which transfer patterns on the steel plate to the toys products surface.
2. Features of liquid pad printing silicone rubber
a. resistance to deformation, high-temperature
b. high printing times
c. good aging resistance
d. exceptional elasticity
e. great printing effect
Operation Instructions of liquidad printing silicone rubber
Pad printing silicone rubber is two-component silicone, part A is liquid silicon rubber, part B is catalyst. The usual mixture of silicone rubber and catalyst is 100: 2 or 100: 3. E.g. we take 100g of liquid silicon rubber and 2g-3g catalyst, mix them and pour it to your mold. A fter 2-4 hours, you will get a Pad
printing silicone rubber.

5. FAQ of liquid pad printing silicone rubber
Why the silicon pad is non-durable?
This problem is caused not by the liquid silicon rubber itself, but in the process of filtering, the filtering handled not properly and impurities are not all filtered out; or in the process of packing as containers not cleaned thoroughly.
As the silicon oil will break the molecular chain of the silicon rubber. More silicon oil added, softer the pad printing will be, meanwhile nondurable and easy ageing it will also turn to be.
Some customers do not know well about the performance of silicon rubber. Actually, the durability of printing pad is closely related to the size of printing pattern. Some factories do not want to take the trouble to change the printing pad. While in fact, for large pattern, large silicone pads should be used, otherwise, use small one.(Generally, the ratio of the silicone pad to printing pattern is 3:1)
