Liquid Silicone Rubber for Statues Molds Making
Tool,Brush,Paint Brush Fenghua Jade Motor Co., Ltd. , http://www.nscuttingdisc.com
liquid silicone rubber for statues molds making are used for:
Mold duplication and delicate mold making for Gypsum statues, cement statues, poli crafts, resin crafts lighting and candle crafts
Features of Mold making liquid silicone rubber:
(1) Silicon rubber for pad printing with SGS and RoHs approval
(2) Curing agent arrange together as free charged
(3) In liquid form and in various colors
(4) With an exceptional fluidity and good operability.
(5)Temperature and deformation resistance as well as low shrinkage.
(6) High duplication times.
(7) Sample orders are available
(8) MOQ: 100KG
Frequent asked questions of liquid silicone rubber for statues molds making:
Why is the appearance of the finished mold striate and unsmooth?
It is because the appearance of the product or the model itself is not perfect, and it has not been polished before the further operation. So when you make silicon molds, firstly you should Polish the product, spray the mold spray evenly on the product. In this case, the problem can be avoided.
OPERATIONÂ PROCEDURES
1. Stir the liquid silicone (Part A and part B) well before use (except when depending on machine).
2. Weigh the desired amount of part A into a clean mixing container,and then weigh the proper amount of part B into the container. Mix the two component together by stirring with a stick. Scrape the container walls and bottom well to insure a thorough mix.
3. Though it is often unnecessary to deair the material due to its low viscosity and our special formulation,it is better to do so to obtain a bubble free rubber. If so,place the container into a vacuum chamber and evacuate the entrapped air from the mixture using a vacuum pump capable of achieving 29 inches of mercury vacuum. The mixture will rise,crest and then collapse in the container. Interruption (bumping) of the vacuum may be necessary to prevent overflowing the container. Keep the mixture under full vacuum for 2-3 minutes.
4. Bleed air slowly into the vacuum chamber. When the chamber is at atmospheric equilibrium,remove the cover plate and take out the container.
5. Pour the deaired material slowly in a steady stream from one end of the mould so that the material flows evenly over the pattern. This should minimize entrapment of air bubbles under the flowing material. A "ready" mold may be poured firstly over the pattern,which will also help reduce the possibility of entrapping air on the pattern and in the cured rubber. A mold release agent may be applied on the pattern first to improve release.
6. Allow the rubber to cure for 2-4 hours at 24C before removing the cured rubber mold from the pattern. Heat acceleration is recommended if necessary
