Ratio 100: 2 RTV-2 Silicone Rubber Mold Making Liquid Silicon for Plaster Molds

Description of RTV 2 molding silicone rubber for ornamental plaster
Condensation Cured RTV2 Silicone Rubber is generally named as two-part room temperature cure silicone rubber, which features an exceptional fluidity and good operability. When mixed with 2% curing agent, they can still be operated within 30 minutes, but will be formed after 4-6 hours. With resistance to deformation, high temperature, acid and alkali, and expansion.

Main applications of RTV 2 molding silicone for ornamental plaster
#Construction of moulds for gypsum, soap, candles, concrete, artificial (very lightweight) stone, wax or custom moulds;
#Decorative building moulds (cornice, column, balustrade, ceilling roses, pedestals, fountains, mantels, wall ornament, planter etc;
#Resin crafts, epoxy resin crafts, poly resin crafts, polyester resin;

Procedures of mold making by RTV 2 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 2-3%, e. G. To 100g silicone rubber should be added 2g catalyst and then mix them thoroughly. (Note: The weight of the silicone and catalyst should be weighed correctly).

Pouring the mixture and curing
Pour the misxed Part A base silicone and CA-30 curing agent as soon as possible onto the original, avoiding air entrapment. The catalyzed material will cure to a flexible rubber within 6 hours(or faster by different mixing ratio or room temperature), we advice you de-mold after 24 hours, it is will improve the replicate times of silicone mold.
