Product Description

RTV2 Tin cure Liquid Silicone Mold Rubber for Gypsum,Plaster, Concrete Mold Making

Description of Mold Making Silicone rubber
RTV2 Tin-based silicones, also called condensation cure silicone, are two-component materials which can cure at room temperature to flexible, high tear-strength rubbers. Tin cured silicone can be poured onto models or they can be made brushed by adding a thixotropic additive. They are ideal for molds where easy release or high temperature resistance (Max 200 C) is required.


Characteristics of Mold Making Silicone rubber
Tin cure silicone rubber for molding is white or translucent flowing liquid with general hardness of 15-60shore A after curing. Molding silicone rubber is a kind elastic silicone rubber mold which features with resistance to deformation, high-temperature, acid-alkali and expansion as well as high reproduction times, good tensile strength, tear strength and elongation, Stripping the gender is good, Linear shrinkage rate low, Size stability is good.

Applications of Mold Making Silicone rubber
Tin cured silicone can be used for casting polyurethane, epoxy, polyester resin, PU resin, cement, plaster, gypsum, candle, soap, waxes, toys crafts, poly resin crafts, Lighting, plastic toys, stationery gifts, statue, relieve furniture, furniture decorative materials, artificial stone, building decoration material, sculpture, sandstone, low melt alloys/metals, urethane and so on.

Instructions for Mold Making Silicone rubber
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 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 minutes 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.
