Condensation type mold silicone rubber
100:2 two-component liquid silicone rubber belongs to condensation type mold silicone rubber. When part A and B are mixed in 100:2 weight, the crosslinking reaction can occur, and the elastic body with certain hardness is formed after curing. It has many advantages, such as good fluidity, easy to operate with low viscosity. After curing, it has heat resistance, high temperature resistance, corrosion resistance, solvent resistance, high tensile and tear strength, low linear shrinkage, high turning model times. It is a cast of gypsum, cement, POLY-RESIN, PU, AB water, ABS material of the elastic mold material, it is widely used in the production and reproduction of sludge, toys, gifts, reliefs, statues, city sculpture, cement products, hand plate, car model, model of home appliances, mold products such as soap.

Products Procedure
1. Choose smooth material to make the mold frame, such as an acrylic plate.
2. According to the actual situation, the master module is put in the frame and fixed.
3. Spray a little release agent in the female die and the die frame wall.
4. The silicone rubber and curing agent are mixed in 100:2 weight ratio and fully mixed evenly.
5. Vacuum exhaust bubble treatment.
6. Pour the bubble in the mold into the mold box.
7. Put the model frame into the vacuum machine according to the actual situation,. (optional).
8. Wait for stripping can be cured.
Precautions For Use
1. Before large-scale use, please do small amount of trial, familiar with the production skills to avoid errors.
2. Do according to the manufacturer's instructions ratio for quantity, and the weighing accuracy, please remember that the ratio is by weight rather than volume. After the mixing of AB silicone rubber, stir it fully to avoid not cure or incomplete cure.
3. If you want to speed up the curing time, you can heating up when liquid silicone rubber initially solidified, but could not heating up immediately after pouring which will cause non-curing because of the volatilization of curing agent.
4. When mixing the AB silicone, mixing in the same direction. When pour glue, take a little bit of the higher and same position on the female die on the same position, let the glue flow flat on the master die, it will increase the flow time of the glue to reduce the bubble.
Q: What is mold liquid silicone rubber?
Answer: Mold liquid silicone rubber is a kind of liquid silicone rubber that is usually used to make molds. It has a liquid state that allows it to flow and fill the mold during the mold-making process, and then solidifies into a silicone rubber mold that is resilient and durable.
Q: What are the main characteristics of mold liquid silicone rubber?
A: It usually has excellent fluidity, easy filling of mold details, high precision, high elasticity, tear resistance, wear resistance and good chemical stability.
Q: What is the main use of mold liquid silicone rubber?
Answer: Mainly used to make various types of molds, such as cultural artworks, industrial parts, toys, handicrafts, models, complex castings, etc. It can also be used to reproduce finely detailed surfaces.
Q: What is the production process of mold liquid silicone rubber?
Answer: The usual process of making a mold includes steps such as preparing the prototype, mixing liquid silicone rubber, pouring or coating the prototype, waiting for solidification, and removing the silicone rubber mold from the prototype.
Q: How to choose suitable liquid silicone rubber for molds?
Answer: When choosing liquid silicone rubber, you must consider factors such as prototype material, mold use, required hardness, durability, temperature resistance, etc., and select the appropriate type and formula according to your needs.
Q: How safe is the use of mold liquid silicone rubber?
Answer: Liquid silicone rubber is generally safe and easy to use, but you should follow the safe operating guidelines provided by the manufacturer during use, avoid contact with skin and eyes, and operate in a well-ventilated environment.
