1.Mainly application of silicone mold making rubber
Silicone mold making rubber is a two part silicone rubber and curing with tin catalyst. As
with alow viscosity, high strength and excellent duplication times,
it's widely usedfor concrete casting and cement products casting,
making silicone molds for artificialstone, concrete statue
molds, garden statue molds, stone molds, cement crafts,
The quality of ourrtv silicone rubber is similar with Dow corning
silicone, Wacker silicone, smoothon silicone, but the prices of our
silicone rubber is more competitive thanthem.
2. Features of RTV silicone mold making rubber
a. low viscosity
b. easy operation
c.long shelf life over 12months
d. high strength and lowshrinkage
e. curing at room temperaturewithin 2-4hours
f. high duplication times andno deformation
3. How tomaking stone mold with RTV silicone mold making rubber ?
Select a mixing container 4-5times larger than the total volume of
material to be mixed.
Weigh out the selected siliconrubber and catalyst. Stir
for several minutes scraping the sides andbottom of the container
carefully to produce a homogeneous mixture.
When using power mixers, avoid excessivespeeds, which could entrap
large amounts of air or cause overheating of themixture, resulting
in shorter pot life.
The air entrapped in the mixing stepneeds to be removed to
eliminate voids in the cure product. This can be done byexposing
the material to a vacuum of 10-20 mbar. The material will
expand,crest and reduce to about the original level. Degassing is
usually completeabout two minutes after frothing ceases.
After mixing the twoparts combination, the material will
cure at room temperature. Selection ofthe Beta will determine cure
speed, the work life as well as the demouldingtime.
The system is sensitive to changes inheat and humidity and
therefore variations in cure speed may be seen if one orboth
variables are changed.
