Features of RTV silicone rubber
RTV silicone rubber for statue mold making is flowing liquid with general hardness of 22-50A° after curing with features:
1. resistance to deformation and high-temperature, acid-alkali and expansion
2. good tensile strength, tear strength and elongation
3. high reproduction times
How to make silicone molds
The simple silicone rubber mold consists of two-component flowing liquid, the component A is silicone rubber, and the component B is curing agent. Mix the silicone rubber and the curing agent evenly, for example, take silicon rubber of 100g and add curing agent of 2g. (Notes: the silicone rubber and the curing agent must be mixed evenly, otherwise the mold will appear uncomplete curing phenomenon. The drying and uneven curing parts will influence the service life and molding times of the silicone rubber mold, and even causing mold wasting.)
Deairring and air bubble eliminating handling of simple silicon rubber mold:
After the silicone rubber and the curing agent are mixed evenly, then take it to deair and eliminate air bubbles. The deairring process should not last too long and not exceed 10 minutes under the normal circumstances. If the deairing lasts too long, the silicone rubber will be cured at once after crosslinking reaction,thus, it is unable to brushing or pouring. In this case, the silicone rubber is wasted, the operation shall be restarted.
Brushing or pouring process fo simple silicon rubber mold
put the deairred silicone rubber onto a product in a mode of brushing or pouring. (Release agent or insulating agent shall be applied on the product or model to be molded before pouring the silicone rubber.) Then, brush the silicone rubber onto the product evenly. 30 minutes later, apply a layer of glass fiber cloth to reinforce the tear and tensile strength of the silicone rubber. Repeatedly, brush another layer of silicone rubber and another layer of glass fiber cloth, it will be done after two times of brushing. In this case, the service life and the molding times of the silicone rubber mold are relatively improved much, the cost is saved and the efficiency is improved as well.
