Usage
1. To add 2-4% curing agent based on the weight ratio and currently mix and to use it right after it was ready.
2. Stirring the mixed rubber material, and then put it into the vacuum box for air extracting 3--5mins. The mold can be made after defoaming.
3. The curing rate of this product is closely relevant to the temperature. The higher temperature is or greater humidity is, curing speed is faster. On the basis of weather condition, users can adjust the curing agent dosage, thus reaching the best curing time.
Packing, Storage and Attentions:
1. In general, the liquid silicone rubber is packed in iron drum, 25KG/drum, and the curing agent is 1L/plastic bottle.
2. Sealed for the products, and store it in the cool place, avoid rand and sun exposure.
3. The storage period is half a year. If there is an increase in viscosity, stir it before using, the performance will be same. It can be used after re-tested when it exceed the storage period.
4. The product is non-dangerous. During the operation, try to prevent any possibility of eyes and skin contact with the curing agent. In case of touching it, wash the affected skin thoroughly by soap, flushing with clean running water immediately for 5minutes at least, and then consult the doctor if necessary.

We can provide liquid additional cure silicone rubber with different hardness.
1. For small size and dttailed pattern(within 30cm), 15-20 shore A can be applied, which is easy for de-molding and will not damage the patterns.
2.For the products with medium size, such as 50cm, 25-30 shore A silicone rubber should be used.
3.For products with large size, such as 1m, 35-40 shore A shall be recommend to avoid deformation.
4.If the product is large but features detailed pattern, 30 shore A silicone rubber will be workable.(It will be better to protect the products from deformation to make outer mold.)
Note: All the above products hardness could be customized or adjusted according to customers' requirements.
Applications of liquid silicone rubber
Jingyi Silicone Material Co.ltd. is meanly produce: soap & candle mold silicone; RTV2 liquid silicone rubber for molding; plaster moulding gypsum decorative products mold making white silicone; medical grade skin color silicone liquid rubber for artificial human prosthesis like artifical finger; artificial penis silicone raw material rubber; 3D concrete bricks and Nordic style walll panels flexible molds; garden statues cement molding silicone; these room temperature silicon rubber are with different parameters for various materials of products, such as: polyurethane casting materials mold, high burn resistant resin products, scented stones, wax products, polyester , fimo pulp, paraffin, metal crafts, alloy, and food moulds,transparent insole, FDA food grade nipple, epoxy product, fiber rein forced platic composite products recycling vaccum bag bagging making. There are two-componet, rapid molding liquid silicone rubber, with sound property of high and low temperature resistance,these molds can achieve the unshriking effect, and non-toxic and un pungent. It is of high transpancy and can endure hear to 300℃ -500℃ for our addition high temperature silicone rubber for molding.
FAQ
1. What’s silicone products you are making?
--liquid silicone, silicone rubber, silicone oil; Due to different silicone molds, our silicone has different viscosity, and cause different hardness, density to meet the requests from client.
2. Do you offer free sample to client?
--Yes, we can provide the sample for test.
3. How about the quality control in your factory?
--We have professional QC team to control the quality during production. Goods will be 100% inspected before shipment.
4. How to remove the bubbles during my mould making?
--After mixing liquid silicone with curing agent, please put the material into vacuum machine to take off the bubbles.
5. How to get good silicone mould to use longer time?
--The best way is:
1, Please choose the right liquid silicone according to your products.
2, Don’t use any silicone oil in mold making, because it can make the silicone mould become too soft to use.
3, Silicone mould can be used longer after the whole silicone mould fully cured, so it’s better to wait 2 hours after mould finished.
6. Why silicone rubber add curing agent after mixing a lot of bubbles?
--This is normal physical phenomena. The liquid will produce a large number of bubbles in the mixing time, so, it must pass through the vacuum exhaust bubble treatment.
