liquid silicone rubber for mold making
High Strength Good Flowability Flexible Silicone Liquid Rubber for Making GRC Molds
Silicone liquid rubber is called Tin cure silicone rubber which is also called condensation-cure silicone mold rubber, these are high-tear silicone mold rubbers that are known as the “work horse” of the industry because of their performance and economy. Tin cured silicone molds are used for casting wax, cement, gypsum, polymer modified gypsum, resins, etc.

Instruction of RTV-2 silicone liquid rubber:
METHOD OF USE
The surface of the original should be clean and free of any dust or loose material. If necessary, particularly with porous surfaces, a suitable release agent should be used.
Pour out the required amount of white base in to a container, weigh it and measure out the correct amount of catalyst at a ratio of between 100:2 to 100:4 by either weight or volume. Gently mix the two components together avoiding as much air entrapment as possible until a uniform colour is achieved. Pay particular attention to the sides and base of the container.
The silicone can now be gently poured at lowest point into the mould box in ensuring that any of the air bubbles burst over the rim until the level of the liquid in box has risen sufficiently over the master models highest point. During this process it is advisable to pour the mixed material in a long streaky stream which also helps in bursting air bubbles introduced during mixing.

Storage and Precautions of silicone liquid rubber:
RTV-2 silicone rubber for making art crafts, which is an environmentally-friendly liquid silicone product, is not easy to burn and can be stored and transported as non-hazardous goods. The shelf life of the product is about one year from the date of production. Inspection is required when exceeding the time limited. It can continue to be used in case of neither thickening nor deterioration.
Why does the silicone rubber mold have few molding times?
The silicone rubber mold has few molding times is due to follwoing reasons: adding too much silicone oil which will destroy the molecular of silicone rubber; making the mold for small and fine detailed products with higher hardness silicone rubber which is easy to break; making the mold for large products with soft silicone rubber which will reduce the tensile and tear strength of the mold, and the mold will have deformation. Thus, we should take the proper silicone rubber to make the mold for suitable products.
