Product Description

RTV Silicone (room temperature vulcanization silicone) is a type of silicone rubber made from a two-component system (base plus curative; A+B) available in a hardness range of very soft to medium - usually from *5 Shore A to *0 Shore. RTV Silicones can be cured with either a platinum catalyst or a tin catalyst. Applications include making molds for reproducing.

RTV silicone rubber applications
RTV Silicone Rubber will reproduce the finest detail and is suitable for a variety of industrial and art related applications including prototypes, furniture, sculpture and architectural elements. RTV Silicone Rubber can also be used to cast a variety of materials including wax, gypsum, low melt alloys/metals and urethane, epoxy or polyester resins (without using a release agent).

Operation instructions for making a mold by RTV silicone rubber
Correct mixing ratio
Component A is silicone rubber, and component B is curing agent or vulcanizing agent. Usually the mixing ratio will be **3%, e.g. to **0g silicone rubber should be added 2g catalyst and then mix them thoroughly. (Note: the weight of the silicone and catalyst should be weighed correctly). 

Storage and Precautions of RTV*2 silicone rubber for making art crafts:

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.
