Special silicone rubber for heat transfer printing, clothing signs (adhesive drop)
summary
The addition molding silicone rubber for clothing signs is a two-component liquid silicone rubber. After adding an appropriate amount of bridging agent, it is fully vulcanized after baking to form a flexible elastomer. It is composed of two components AB, with a ratio of 10:1 or 1:1.
characteristic
1. Rapid curing and high production efficiency.
2. Small shrinkage and high precision.
3. It can be firmly bonded with fiber and cloth without falling off.
application
Trousers and clothes. Shoes signs, clothing prints.

Processing program
1. Weigh the required amount of component A, put it into a container 3-4 times larger, add component B with a weight ratio of 10:1 or 1:1 in proportion, fully stir and mix it evenly, and then use it after vacuum deaeration.
2. The operation time at 25 ℃ is 20-40 minutes, and it can be vulcanized within 80 ° C~120 ℃/30-40 minutes.
3. The operation time and curing time can be adjusted according to customer needs.
storage
To ensure the good quality of this product, it should be stored in a dry environment at room temperature of 25 ° C and in a sealed container. It should not be in contact with water or moisture to prevent viscosity increase, operation, time change and other deterioration.
Note that phosphorus, sulfur, amine, organic tin and other compounds may be poisoned by catalyst, which may cause the phenomenon of immature.
Conventional packaging
Packed in 25kg drums or 200kg drums.
