Detailed

Features of mold making liquid silicone :

Shoes mould Making RTV-2 Silicone Rubber is a two-component material, and RTV-2 silicone rubber is consisted of Part A silicone base and Part B curing agent, and the silicone base and curing agent can cure at room temperature by a condensation reaction. These materials can be cast into the cured silicone mould : shoe mould making, sand casting etc.

Characteristics of mold making liquid silicone

1. Good flow ability and long working time

2. Medium hardness stone mold making

3. High tear and tensile strength

4. Easy de-mould from complex replica parts

5. Acid and alkali-resistance

6. Low linear shrinkage

Applications of mold making liquid silicone

Instructions for mold making liquid silicone

1. Make sure the surface of the original is clean and free of loose material.

2. Weight 100 Part A base and 2 parts of CA30 Curing Agent in a clean container.

3. Stir Part A base silicone before use thoroughly , as filler separation may occur upon prolonged storage.

4. Mix Part A and Part B evenly until the it completely dispersed in the base.

5. Pour the mixed Part A base silicone and curing agent B as soon as possible onto the original

6. De-mold after 24 hours ,it is will improve the replicate times of silicone mold.

Note:It is strongly recommended that entrapped air be removed in a vacuum chamber, allowing the mix to completely expand and then collapse. After a further 1-2 mins under vacuum, the mix should be inspected and can be used if free of air bubbles. A volume increase of 3-5 times will occur on vacuum de-airing the mixture. So a suitably large container should be chosen.

Storage of Shoe soles mold making

When the Shoes Mold Making RTV-2 Silicone Rubber is stored at or below 30 °C (85°F) in the original unopened containers, HY-625 HY-630 silicone base and curing agent have a usable life of 12 months from the date of production.

Note of Shoe soles mold making

Shoes Mold Making RTV-2 Silicone Rubber is an industrial product and must not be used in food molding, dental human skin molding applications.
