Mingyi silicone（anhui）co,.ltd
This 10:1 two-component liquid silicone is an addition-cure fully transparent liquid mold silicone. After curing, it features high transparency, high tear resistance, almost no shrinkage, good stability, excellent demoldability, and no deformation. It is an elastic mold material for pouring AB resin, PU, epoxy resin, 815 resin, polyester resin, PT, and ABS materials.
It is used in the production and replication of precision molds, precision machinery, resin jewelry, and fine products. It is an addition-cure two-component liquid silicone rubber.

The above parameters are not comprehensive and can be adjusted according to your requirements.
Mixing: Mix Component A and Component B at a weight ratio of 10:1 and stir thoroughly until uniform.
Defoaming: For applications with high requirements, vacuum defoaming treatment should be conducted; otherwise, the produced mold will have air bubbles.
Pouring: Pour the well-mixed liquid silicone into the mold frame.
Before large-scale use, conduct a small-scale test first to master the product's usage skills and avoid mistakes.
Take the amount according to the manufacturer's instructions and weigh accurately. Remember that the ratio is by weight, not by volume. After mixing Components A and B, they must be fully stirred until uniform to avoid non-curing or incomplete curing.
When making the mold frame, if 502 glue is used, wait for half an hour or place it in an oven at 50℃ for 10 minutes before pouring the silicone. This prevents the 502 glue from reacting with the silicone (causing "poisoning") and leading to non-curing.
To accelerate the curing time, a temperature increase method can be adopted to speed up the curing rate of the silicone.
When mixing Components A and B, stir in the same direction. When pouring the silicone, hold the container high and pour it little by little onto the same position of the master mold, allowing the silicone to flow and level naturally on the master mold. This can extend the flow time of the silicone and thereby reduce air bubbles. Due to its high viscosity, this product requires vacuum defoaming treatment.
The 10:1 addition-cure series products will undergo a "poisoning" reaction with compounds such as tin, phosphorus, ammonium, chlorine, carboxylic acid, thiol, and hydroxyl groups. During use, contact with such compounds must be prohibited to avoid non-curing.
