rtv-2 silicone for mold making Applications:

molding making silicone rubber with the hardness of 38-42 shore A, is specially suitable for large crafts mould making and duplication of poly resin crafts in pouring way, PU crafts, gypsum or plaster, unsaturated resin, lighting and candles crafts, plastic toy, stationery gifts crafts, large statue buddha, furniture decoration, cement, articficial stone, etc.

rtv-2 silicone for mold making Advantages: light viscosity, pourable effort, good fluidity, easy-operation, good tension and high tear strength.

Description of rtv-2 silicone for mold making:
molding making silicone rubber mainly used for shoe molds, sand casting, sole sampling, plaster models,

simple products, products with noncomplex patterns, as well as product models with stable size and non-deformation.

Using rtv-2 silicone for mold making advantages:

* Reusable
* Molds can be used over and over again.
* Does not shrink
* Has good abrasion resistance.
* Comes in a wide range of hardnesses and therefore gives long mold life.
* Can be poured, brushed or sprayed on to the original model.
* Is the most economical overall (compared to other mold rubbers).

Frequently asked questions of rtv-2 silicone for mold making

Why the molding making silicone rubber appear with weak tear strength?

When making silicone rubber mold, some customer add a lot of silicone oil to reduce the viscosity of silicone rubber. In fact, this has the opposite effect. The tension and tear strength will be reduced badly with the addition of silicone oil, which leading to the weak and flimsy condition of silicone rubber molds.
