Description of mold making&casting material silicone rubber

mold making&casting material silicone rubber (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 15 Shore A to 40 Shore. RTV Silicones can be cured with either a platinum catalyst or a tin catalyst. Applications include making molds for reproducing.

Using Instruction of mold making&casting material silicone rubber :

Component A is white flowing liquid and component B is the curing agent. For example, take silicone rubber of 100g and add 2% curing agent for  mixing evenly. After the silicone rubber and the curing agent are completely mixed, put the silicon into a vacuum machine for deairing to remove the bubbles. After deaired, pouring the liquid silicone rubber into the product to be duplicated or into the mold frame.

Note: the product is used for pouring or brushing technique. That is to say, fix the product or sole model to be duplicated onto a plane plate, then enclose the plane frame with wooden plates to prevent the leakage of the silicon , mix the silicone rubber and the curing agent evenly according to the mixing ratio of 100 : 2 and pour them onto the sole model, then brush evenly with a wooden plate or a brush, and fill up the mold frame with gypsum after the silicone rubber is dried.

Storage and Precautions for mold making&casting material rubber:

The product, 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.
