High transparency
mold making silicone rubber
10: 1 two-component liquid silicone rubber is an addition
type liquid silicone mold rubber, the
product has a high transparency after curing, high tear resistance, almost no
shrinkage, Good stability, good mold release, no deformation and so on. It is
an elastic mold material for filled with AB water, PU, epoxy resin, 815 resin,
Polly resin, PT, ABS material and so on.

Procedure
1. Mixing:
The A and B rubber 1: 1 weight ratio mix and stir evenly.
2. Discharge
bulbs: For high requirements should be evacuated discharge bubbles, otherwise
the mold will have bubbles.
3. Material
pouring: pour the mixing the stirred liquid silicone into the mold box.
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. When make the mold frame, if 502 glue is applied, pour
the mixing silicone rubber after half an hour or put it into oven at 50℃ for 10 minutes, to prevent 502 glue and silicone poisoning to make it not cure.
4. To accelerate the curing time, heating method can be
used to speed up the curing rate of silicone rubber.
5. 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. Generally, the silicone in hardness higher
than 20, it will need to do vacuum pumping before use.
6. 1:1 Additional products will have toxic reaction with tin,
phosphorus, ammonium, chlorine, carboxylic acids, thiol, hydroxyl and other
compounds. It is forbidden to contact with such compounds to avoid the
occurrence of non-curing.
