[Sell] RTV silicone rubber for pad printing View details for: RTV silicone rubber for pad printing
The pad printing silicon rubber usages:
The silicon rubber is mainly use for printing irregular patterns of plastic toys, electroplating toys, trade makers .Silicon pad printing is a carrier which transfer printing the patterns on the steel plate onto the toys products surface.

Pad printing silicon features:
Pad printing silicon rubber with high print times and abrasion resistance, without any inpurities, with good printing effects, permanent and durable,we can provide all kinds of colors are available and our catalyst is free charged.

Pad printing silicon rubber operation instructions:
Pad printing silicon rubber is two-component silicone, part A is the liquid silicon rubber, part B is the catalyst. The usual mxing ratio for silicone rubber and catalyst is 100 : 2-3, eg. we take 100grams of liquid silicon rubber,then we add 2-3 grams catalyst, mix then evenly and pour it to your mold. Then after 2-4 hours, you will obtain a printing pad.
Frequently asked question of pad printing silicon rubber:
The reasons why the silicon pad has a short service life are listed as follows:
(1)The problem caused by inappropriate filtration of silicone rubber, and impurities in the packaging process due to the uncleanness of barrels and bags.
(2)The short service life of the silicone pad has a close relationship with the adding amount of silicone oil. The more the silicone oil added, the softer the silicone pad will be. The silicone oil will destroy the molecule of the silicone rubber, thereby bringing about the non-durable and easy ageing of the silicone pad.
(3)All the users should know the properties of pad printing silicone rubber. The service life of the silicone pad has close relationship with the size of the printed patterns. For example, if a big pattern to be printed, a big silicone pad is required; if a small pattern to be printed, a small silicone pad (the silicone pad has to be adjusted according to the size of the patterns, and the proportion between the size of the silicone pad and the pattern is 3:1.)

Detailed Product Description
Usage of Liquid silicone rubber for sculpture mold

Liquid silicone rubber for sculpture mold is intended for making silicone rubber mold for resin crafts, candles, plastic toys, relieve furniture, architectual decoration, furniture decoration, sculpture and so on.
Feature of Liquid silicone rubber for sculpture mold
Liquid silicone rubber for sculpture mold is flowing liquid with general hardness of 22-50 A ° after curing with features:
1)low shrinkage 2)good operation 3)high tear and tensile strength 4)curing agent free 5)easy de-mold 6)high reproduction times 7)resistance to deformation and high-temperature, acid-alkali
Operations of Liquid silicone rubber for sculpture mold

If customers want to make large products and large size moulds, the mould should be made of silicone rubber with high hardness. On the contrary, if the mould with fine and precision patterns, it should be made of silicone with low hardness. The amount of the curing agent depends on the actual requirements of the customer. If mould requiring fast drying and demould, more curing is needed.

(Note: our company does not recommend you to add silicon oil. If a special soft silicom mould or fine detailed and complex patterns products are required, 5% - 10% silicon oil could be added to soften the mould for easy demould.)
