Description of RTV silicone rubber for sculpture & statue molding

 

RTV silicone rubber for sculpture & statue molding, rtv-2 mold making silicone rubber is generally named two-components silicone rubber, Part A is a flowable liquid, part B is the curing agent. It features an exceptional fluidity and good operability. The mixing ratio is 100:2,mainly be suitable for making stone molds application.

 

 Mainly application of RTV silicone rubber for sculpture & statue molding

 

  RTV silicone rubber for sculpture & statue molding is a two part silicone rubber and curing with tin catalyst. As with a low viscosity,high tear strength and excellent duplication times,it's widely used for concrete casting,cement products casting,Making silicone rubber molds for artificial stone,concrete crafts,cement crafts,GRC/GPR decorations casting.

3.How to making stone mold with rtv2 silicone rubber?

 

Mixing:
Select a mixing container 4-5 times larger than the total volume of material to be mixed.
Weigh out the selected silicon rubber and catalyst. Stir for several minutes scraping the
sides and bottom of the container carefully to produce a homogeneous mixture. When
using power mixers, avoid excessive speeds, which could entrap large amounts of air or
cause overheating of the mixture, resulting in shorter pot life.
The air entrapped in the mixing step needs to be removed to eliminate voids in the cure
product. This can be done by exposing the material to a vacuum of 10-20 mbar. The
material will expand, crest and reduce to about the original level. Degassing is usually
complete about two minutes after frothing ceases.

 

 

 

Curing:
After mixing the two parts combination, the material will cure at room temperature. Selection of the Beta will determine cure speed, the work life as well as the demoulding time.

 

The system is sensitive to changes in heat and humidity and therefore variations in cure
speed may be seen if one or both variables are changed.
