Platinum Cured Pad printing Silicone

Product Descritpion:

Pad printing silicone rubber is applicable to produce printing pads, mainly used for printing the irregular patterns on plastic toys, electroplating products, electronic toys, trademarks, etc.

Features:

- High printing times and good printing effects

- Good tensile and tear strength, low shrinkage

- No Particle(Without any impurity)

- Resist the friction and good resilience

- Different color(such as red, green, yellow, etc) are available

- Great fluidity and easy to operate

Technical Data:

Storage & Shelf Life:

1Year at least, stored in a cool and dry place under room temperature 25℃

Pad Printing Silicone PA30# Base is available in 20kg containers – 18kgs A + 2kgs B.

OPERATION of making silicone rubber printing pads:

Step 1: prepare the original silicone pad molds
Make sure your original molds smooth and Clear .

Step2: Mix 9 part of A liquid silicone and silicone oil
Usually the original hardness of the silicone pad is around 30 shore A , our customer will add silicone oil by adjust the hardness , when adding 2% silicone oil , the hardness will reduce 1 shore A , for example PA30 silicone is 30 shore A , if you require hardness of 25 shore A for printing , then add 10% 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.
＊Notes: 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 electronic weight..
If not , for example add two much catalyst , the operation time will be too fast to operate ,which will cause inconvenience to operate .
         2.Mixture should stir evenly.
Otherwise the silicon rubber will be partly solidified and this will give birth to difficulties in your final operation. What’s more, the finished molds will meet a short life. All of these will cause a waste of silicon rubber.

Step4: Vacuum pumping
Without exception, this step takes less than 10 minutes. Otherwise, it will cause cross linking reaction, and no more further steps will be available.

Step 5: Pouring the mixture into the original mold
＊Notes:1. 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 pad .
        2.Wait till the silicone pad totally cured before put into production.

1).The following material may hinder the curing of PA30#, so please use after the test. When necessary, please clean the application areas.

Organotin compound or Condensation silicone with organotin Sulphur sulfide and sulfur rubber materials. 

Amine compounds as well as contains the amine materials.

Pewters solder flux

2). PA30 should be sealed storage.The mixture should be used up disposably to avoid causing waste.

3).PA30 belongs to non-dangerous goods, but keep away from mouth and eyes.

4). When it gets stratified after a period of storage, Please mix it evenly before using, which does not affect the performance.
