Liquid silicone for resin, craft products

Liquid silicone for resin, craft products application: 

Liquid 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 silicone for resin, craft products Usage:

For the duplication and mold making of glass crafts, lighting, candle, culture relics duplications.

Liquid silicone for resin, craft products 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.

Liquid silicone for resin, craft products 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.

The proportions and reactions of the curing agent and the silicon are listed as follows:

1. Adding curing agent 1%, the silicon can still be operated within 2.5 hours and can be demoulded after 6-8 hours.

2. Adding curing agent 2%, the silicon can still be operated within 50 minutes to 1 hour and can be demoulded after 2-3 hours.

3. Adding curing agent 3%, the silicon can still be operated within 28 - 30 minutes and can be demoulded after 1.5-2 hours.

4. Adding curing agent 4%, the silicon can still be operated within 10 - 15 minutes and can be demoulded after 1 -1.5 hours.
