In our lives, we can see the shadow of silicone everywhere. Similar to coatings on the bottoms and ankles of silicone anti-slip socks, anti-slip silicone sports gloves, anti-slip underwear strap coatings, etc.
With the rapid development of the screen printing industry, screen printing silicone is widely used on various fabrics.
Because the composition of fabrics is different, some fabrics are not firmly bonded to the silk screen silicone. So how should we solve this kind of problem?
1,First analyze the composition of the fabric
There are many types of fabrics. The currently common nylon fabrics and Lycra fabrics are relatively difficult to bond! Special treatment agents are required, which can solve the problem of weak bonding of various screen printing silicone gels. Just add a small amount of treatment agent and it can be solved.
2,Silicone and cloth poisoning
There are two reasons for poisoning. One is poisoning by black fabric (the dye of black fabric contains heavy metals such as tin, lead and sulfur, which are not environmentally friendly, which can cause poisoning of silk screen printing silicone). The second is that during the heating process, the high temperature will destroy the fabric. The fibers on the surface are charred and carbonized. This situation will also cause the fabric to be poisoned and not solidified! These two problems can be solved by adding a certain amount of platinum catalyst (platinum catalyst has strong anti-poisoning properties and efficient catalysis).
3,Make sure the mixture is evenly mixed
Confirm whether the screen printing silicone is stirred evenly and whether the curing agent is added according to the proportion: the ratio of screen printing silicone and curing agent is 10:1, 10 parts of silicone and 1 part of curing agent! Be careful: the more curing agent you add, the slower the curing time will be! Never add curing agent just to speed up the curing time, otherwise it will be counterproductive!
