Specifications

RTV liquid silicone for mold making
1. Mold-releasability 2. High tear
3. Dimensional stability
4. Excellent Flowability 

Liquid RTV silicone rubber application: 

Liquid RTV silicone rubber compounds for moldmaking are suitable for mold masters for molding with polyester resin, epoxy resin, urethane foam, wax, plaster, and low-melt-point metal alloys. These RTV rubber compounds allow accurate reproduction of the shape of the original. They are easy to use and are thus used widely in industrial applications, as well as by hobbyists looking to create the perfect replica.

Liquid RTV silicone rubber feature description:

A. Workability

The base compound and curing agent are mixed and then poured into the mold to create a silicone rubber mold quickly. Workable time and cure time can be adjusted. 

B. Mold-releasability

The cured rubber releases easily from the mold, so mold-release agents (soapy water, wax, etc.) are unnecessary.

C.Dimensional stability

These rubbers offer good dimensional stability, with little shrinkage.

D. Flowability

They have excellent flowability, so the original form is reproduced accurately. This includes even intricate shapes and details such as fingerprints and wood grain.

E.Heat and chemical resistance

These rubbers have outstanding resistance to heat and chemicals.

F.Deep-section curability

Moldmaking RTV silicone rubber compound cures uniformly throughout the mold, regardless of thickness

G.Non-exothermic

No heat is generated during curing, meaning no adverse effects to the original.

Molding silicone rubber operations 

If the customer wants to make large products and large size molds, the mold should be made of silicon rubber with high hardness. On the contrary, if the mold with fine and precision patterns, it should be made of silicon with low hardness. The amount of the curing agent depends on the actual requirements of the customer. If molds requiring fast drying and demold, more curing agent is needed; contrarily, if molds requiring slower drying and demold, less curing agent is needed.
