GS-A30(P) platinum cure silicone rubber for pad printing
Description of pad printing
GS-A30(P) is a kind of room temperature vulcanized silicone rubber
also is a addition cure silicone rubber / platinum cure silicone
rubber for making printing pad. Its generally named as two part
silicone rubber with9:1 mixing ratio. Part
A is a flowable liquid, part B is the curing agent or catalyst. Its
mainly used for make
The silicon pad is a
carrier which transfers the patterns from the steel plate onto the
products' surface. It has the advantage of
good printing effects, fine quality, good resilience, and without
Application of pad printing
rubber is used for is mainly use for printing irregular patterns on
plastic toys,shampoo, pen, glass,electroplating
products,electroplating toys and trade marks artwork gifts, and
stationery and so on.
Operation of making silicone
rubber printing pads:
Step 1: prepare the original silicone pad molds
sure your original molds smooth and Clear .
Step2: Mix 9 part of A liquid silicone and silicone
the original hardness of the silicone pad is around 28 shore A ,
our customer will add silicone oil by adjust the hardness , when
adding 2% silicone oil , the hardness will reduce 2 shore A , for
example 933 silicone is 28 shore A , if you require hardness of 25
shore A for printing , then add 6% silicone oil .The percentage of
silicone oil added should not more than 30% . Adding silicone oil
into the liquid silicone and mix it evenly
Step3:Add 1 part of B catalyst into the mixture of liquid silicone
with silicone oil and mix them evenly.
After the Step 2 by adding and mix the silicone oil evenly ,add 10G
catalyst into the mixture (10% is the weight for the totally
mixture of liquid silicone and silicone oil ) and mix them evenly
1.Weigh the exactly weight by
If not , for example add two much catalyst , the operation time
will be too fast to operate ,which will cause inconvenience to
2.Mixture should stir evenly.
Otherwise the silicon rubber will be partly solidified and this
will give birth to difficulties in your final operation. Whats
more, the finished molds will meet a short life. All of these will
cause a waste of silicon rubber.
Step4: Vacuum pumping
exception, this step takes less than 10 minutes. Otherwise, it will
cause cross linking reaction, and no more further steps will be
Step 5: Pouring the mixture into the original
Put an wooden board on the surface of the silicone pad and set an
hole on the board to make sure the board will closely stick on the
2.Wait till the silicone pad totally
cured before put into production.
