1.Mainly application of silicone deformer
silicone deformer is a two part silicone rubber and curing with tin catalyst. As with a low viscosity,high tear strength and excellent duplication times,it's widely used for making garden statue mold,stone mold,concrete statue mold,baluster mold,statue mold,grc moulding,decorative plaster molds,candle molds and so on.
2.Features of High Strength Silicone Deformer for Epoxy Resin Mold
Good cut-growth resistance
High durometer hardness
Low shrinkage
Easy release
Room temperature cure within 24 hours
Heat-accelerable cure
Long mold life
Highly detailed reproductions
Simplified handling

5.How to making stone molds with silicone deformer ?
1. Stir the base (Part A) well beofre use (except when depending on machine ).
2. Shake the catalyst container (Part B) well before use.
3. This is a 100 Part A to 4 Part B mixing ratio by weight.Weigh the desire amount of base into a clean mixing container.
4. Weight the proper amount of catalyst into the container. Mix the base and catalyst together by stirring with a stick until a uniform color is obtained. Scrape the container walls and bottom well to insure a thorough mix.
5.Though it is often unnecessary to deair the material due to its low viscosity some may choose to do so. 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 contanier. Interruption(bumping) of the vacuum may be necessary to prevent overflowing the container. Keep the mixture under full vacuum for 2-3 minutes.
6. Bleed air slowly into the vacuum chamber. When the chamber is at atmospheric equiplibrium,remove the cover plate and take out the container.
7.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 emtrapment of air bubbles under the flowing material. A 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.Shelf life of silicone deformer
Twelve(12) months from date of shipment when stored at 250C in the original sealed packages.
7.Package style of silicone deformer
Packed in clean 25kg/pail, 200kg/pail.
