[1] RTV-2 Mold Making Liquid Silicone Rubber application:

 

- Unsaturated polyester resins, epoxy resins, polyurethane resins

- Polyurethane elastomers

- Natural and synthetic waxes, candle, soap

- Plasters, gypsum, column, cornices, domes, cements, concrete

- Low-melting point

- Imitation wood and bench

 

 

[2] RTV-2 Mold Making Liquid Silicone Rubber features :

RTV-2 molding silicone rubber, silicon rubber are generally named two -component room

 temperature vulcanization silicone rubber, a kind elastic silicone rubber mold which

 features with resistance to deformation, high-temperature, acid-alkali and expansion.

[4] The differences of RTV M 20,RTV M 25,RTV M 30

A.RTV M 20 is mainly used for molds with small, delicated patterns. Pouring method is the best way because of good fluidity. The hardness is 20 shore A.

B.RTV M 25 is for medium size molds making. It’s also used for pouring methods. The hardness is 25 shore A.

C.RTV M 30 is applicable for large mold making since hard hardness. Both pouring and brushing method are ok. The hardness is 30 shore A.

 

[5] RTV-2 silicone rubber instruction:

RTV-2 molding silicone rubber are generally named as two-part room temperature sulfurated

silicone rubber, which features an exceptional fluidity and good operability. When mixed

with 2-5% curing agent, they can still be operated within 30 minutes, but will be formed

after 2-7 hours. With resistance to deformation, high temperature, acid and alkali, and

expansion, silicon flexible molds are used for mold duplication and delicate mold making for

poli  crafts, resin crafts lighting and candle crafts.
