1.Mainly application of Liquid silicone rubber for mould making,mold making silicone rubber  Liquid silicone rubber for mould making,mold making silicone rubber is a two part silicone rubber and curing with tin catalyst. As with a low viscosity, high strength and excellent duplication times, it's widely used for concrete casting and cement products casting,making silicone moldsfor artificial stone,concretestatue molds,garden statue molds,stone molds,cement crafts,GRC/GPR decorations,ect.

The quality of our Liquid silicone rubber for mould making,mold making silicone rubber is similar with Dow corning silicones,wacker silicones,smooth on silicone,but the prices of our silicone rubber is more competitive than them.

2.Features of Liquid silicone rubber for mould making,mold making silicone rubber

Key performance properties:

• Exceptional molding durability to epoxy & polyurethane resins
• High tear & tensile strength
• Excellent release ability
• Low shrinkage (room temperature cure)
• Curing speed can be controlled with retarder ME75
• Low viscosity
• Three types of curing agents available- standard, for strong reverse taper property and for machine mixing

Main applications:

• For making Silicone rubber molds for the Jewelry industry
• Prototype mold making for electric & electronics industry such as TVs, Home appliances, mobile phones, copy machines
• Prototype mold making for automotive industry such as console boxes, radiator grilles, lamp housings

3.How to making stone mold with Liquid silicone rubber for mould making,mold making 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.
