Features of Low Price of Silicone Rubber for Mold Making / manual mold making / shoe sole mold
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 CA30 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 Low Price of Silicone Rubber for Mold Making / manual mold making / shoe sole mold
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
Instructions for Low Price of Silicone Rubber for Mold Making / manual mold making / shoe sole mold
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 CA30 completely dispersed in the base.
5. Pour the mixed Part A base silicone and CA-30 curing agent 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 Low Price of Silicone Rubber for Mold Making / manual mold making / shoe sole mold
When the Shoes Mold Making RTV-2 Silicone Rubber is stored at or below 30 ° C (85° F) in the original unopened containers, RTV3010/3015 silicone base and CA30 curing agent have a usable life of 12 months from the date of production.
Note of Low Price of Silicone Rubber for Mold Making / manual mold making / shoe sole mold
Shoes Mold Making RTV-2 Silicone Rubber is an industrial product and must not be used in food molding, dental human skin molding applications.
