Pad Printing Silicone Rubber features super quality,abrasion resistance, high-temperature resistance, good printing effect, due to the addition of new American material Dupont Teflon which features high-temperature resistance.

Operation Instruction for Pad Printing silicone rubber

1. Firstly,clean the mold with detergent, and dry up the mold by a piece of cloth or an air gun and then coat the mold with a layer of release agent.
2. The normal proportion of the pad printing silicon to the silicone oil depends on the requirements of customers. If pattern has big area to be printed, a soft silicon pad is needed and the amount of silicone oil increases. Contrarily, if a silicon pad of high hardness is needed, less or no silicone oil should be added. The hardness of general pad printing silicone rubber is approximately 15A°~-25 A°; if too much silicone oil is added, the silicon pad is so soft that the printing times is limited, the molecular weight of the silicon will be damaged by the silicone oil no matter how superior the silicone is, which thereby makes the silicone printing pad not abrasion resistant,solvent resistant,or aging resistant any more.
3.?General mixing proportion is as follows: add 30g of silicone oil into 100g of silicon,the hardness of the silicon pad will be 20A°, which is suitable for the pad printing for alloy cars and products with small patterns and contact area. If there is big contact area or a soft silicon pad is needed, the mixing proportion of the silicon and the silicone oil can be 100:30-100:50.?But please note that the larger amount of silicone oil is added, the softer the silicon pad will be, which will reduce times of pad printing, abrasion resistance and solvent resistance. In addition, the times of pad printing will be correspondingly reduced,which will cause increased cost and material waste.
4. The amount of the curing agent and the chemical reaction with the silicon is as follows: mix 100g of silicon and 50g of silicone oil sufficiently and evenly, then add the curing agent which is?2%-3% of the total weight of the silicon and the silicone oil,stir the moxture for 2-3 minutes, and then deair it to remove bubbles. The time of deairring generally does not exceed 10 minutes.If the deairing takes too long,it may cause fast curing of the silicon and impact the quality of silicon.
