RTV-30 30A platinum cure rtv2 silicone rubber

1. Description

Guochuang G-830 is a two-component 1:1 Mix addition (platinum) cured RTV silicone rubber which cures at room temperature. G-830 is a harder material, with a 30A Shore hardness. Because of its relatively low viscosities and strong strength, it is recommended for in the manufacture of flexible molds for casting wax, gypsum, resins, concrete and other materials 

2. Features

*high chemical resistance to the aggressive components of some types of resin

*High resistance to laceration (this characteristic guarantees high resistance to wear and tear)

*High level of accuracy in reproducing very small particulars

*High dimensional stability over time and non-deformability

*Considerable resistance to high temperatures and to ageing

*Excellent non-stick effect*Soft, stretchy, high tear resistance,

*Will not shrink in service

PLATINUM CURE for HIGH PRECISION Jewelery; Art; Industrial & Architectural molds — Highest quality in the world.  Room temp cure TIME OF ABOUT 2 Hours.

Shore hardness of 30A – Will not shrink in service. 

3. Common uses of G-830 Platinum Cure Silicone:

*Wax

*Urethane (polyurethane)

*Plaster Hydrocal, Hydrostone

*Polyester casting resin

*Low melt metals (mold life can be short)

*Cement, Concrete

*Epoxy

*Soap

4. Using instructions

1.Place a plastic container on a small scale, making sure to zero out the weight on the scale. Note: use a container that, during rise under vacuum in Step 5, will allow for material to expand to 4-5 times its resting volume.

2. Pour catalyst into the plastic container, noting weight of material poured.

3. In the same container, pour an equal weight of base on top of the catalyst (e.g., 100 grams of catalyst and 100 grams base). Note: within a 5% weight variance, the end result is not altered.

4. With a clean, dry mixing spatula, mix energetically until the color of the product is homogeneous. Note: working time begins at this step. Mixing should take no longer than 1-2 minutes.

5. Place container under vacuum and vacuum until material bubbles and rises. Release vacuum and repeat until bubbles are removed. Vacuuming should take no longer than 3-4 minutes.

6. From a height of approximately 30 cm, pour the mixed silicone into the mold frame. Maintain the pouring stream in the same spot so as to minimize introduction of air bubbles into the mold.

7. Allow the mold to sit, undisturbed, for at least 4 hours to ensure the silicone is fully cured.

8. Remove the mold from the frame.

9. Cut around the pattern carefully to release it from the silicone rubber mold.

5.Appearance
