rtv-2 25 shore a  for plaster en concrete mold liquid silicone 

 liquid  silicone rubber is generally named two-components silicone

rubber, Part A and part B. It features an exceptional fluidity and good operability. The

mixing ratio is 1:1,mainly be suitable for making molds application.

Applications of  HY-625 Liquid Silicone Rubber 

liquid  silicone rubber could be mainly used for food mold , such as chocolate mold , cake mold , it is also used for making concrete  stones, wax molds, PU molds, resin molds, gypsum casting, candle molding .

Advantages of liquid slicone for molds for making plaster molding

-low shrinkage (less than 0.1% )

-high tensile and tear strength with high copy times

-easy for operation (mixing ratio at 1:1 /10:1)

-good fluidity easy for pouring operation ( in round 10000 cps )

-it is food grade with FDA

Datasheet:

Operation instruction of silicone rubber :

1. Pls clear the model and tool totally before operation to prevent cure inhibition.

2.Weigh the two part correctly by electronic weight in two separate container .

3. Mixing the two part in 1:1/10:1 and stir part A and part B evenly in 2-3 minutes .

4.And get the mixture for vacuum-pumping for de-air the bubble in around 2-3

minutes . (If there is no vacuum machine, pls pour the mixture carefully and slowly

down the side of the mold frame so that less bubbles caused)

5. Enclose the product (the original model) with four plastic plates or wooden plates.

6. Clean your products and brush a layer of release agent(detergent or soap water) on

your product.

7. Pour the vacuumed mixture into the model frame from the side of the mold frame .

FAQ
1.Why does the RTV-2 silicone rubber for molding have few mold making times?
The silicone rubber mold has few molding times is due to following reasons: adding too much silicone oil which will destroy the molecular of silicone rubber; making the mold for small and fine detailed products with higher hardness silicone rubber which is easy to break; making the mold for large products with soft silicone rubber which will reduce the tensile and tear strength of the mold, and the mold will have deformation. Thus, we should take the proper silicone rubber to make the mold for suitable products.
