Product Description

Description

DC-P25 Pad Printing RTV-2 Silicone Rubber is a kind of Tin-cure silicone rubber with the advantages of high temperature resistance, abrasion resistance, good printing effect, etc. , which made of top-quality high-temperature resistance new material made in America, is processed through high-temperature machining.

 

Application

DC-P25 Pad Printing RTV-2 Silicone Rubber is a kind of pad printing silicone rubber to make the printing pads for plastics toys, electroplating products, electronic toys, trademarks and irregular pattern printing. The silicon pad is a carrier which transfer printing the patterns on the steel plate onto the toy products' surface.

 

Step 3:

General mixing proportion is as follows: add 30g silicon oil into 100g silicon then hardness of 20A° printing pad we get, which is suitable for the pad printing for alloy car and other products with small patterns and contact areas. If a big contact surface or a soft silicon pad needed, the mixing proportion between the silicon and the silicon oil can be no more than100:40(means we suggest you do not add silicone oil more than 30% base on totally quantity). But please note that the more silicone oil added. the softer the silicon pad will be, which will also reduce printing times, abrasion resistance and solvent resistance. Therefore, cost increase and material waste will occur.

 

Step 4:

Relation between the amount of the curing agent added and the chemical reaction of the silicon is as follows: mix 100g silicon and 30g silicon oil sufficiently and evenly, then add the curing agent which is 2%-3% of the total weight of the silicon and the silicon oil, keep stirring for 2-3 minutes, and then deair to remove the air bubbles. It is better to finish deair within 10 minutes. For if it takes too long, it may cause fast curing and affect the quality of the printing pad.

Operation instructions

Step 1:

prepare all the tools like the pad mold, a cup for mixing, and a glass stick. Clean the pad mould with detergent, and dry the pad mould with an air-gun or cloth, then brush a lay of mold release agent.

 

Step 2:

Generally, the ratio of pad printing silicon rubber and the silicon oil depends on the size of pattern which customer needs to print. The larger the pattern is, the softer the printing pad should be, and more silicon oil needs to add. Contrarily, if a silicon pad with high hardness needed, silicon oil should be added less or none. General hardness of the printing pad is 15A°~-25 A°. If too much silicon oil added in the silicon rubber, the printing pad will be too soft, and this will limit the printing times. For silicon oil will destroy the molecular chain of the silicon rubber, no matter how supreme quality the silicon rubber is. And therefore, the printing pad will be abrasion intolerant and solvent intolerant and easy ageing.
