| RTV-2 condensation/tin cured soft silicone rubber(M-20P soft hardness) Applications RTV-2 silicone rubber is for small production moldmaking.And molds for of parts in various materials( plaster, wax , reconstituted stone, various resins(epoxy, acrylic, polyester), mortar, silicone elastomer ) such as: - Decorative items: cornices, columns, ornaments, statues…..
- Figurines: toys, candles, statues, giftware, soap, craft projects, sculpture
- Furnishing: casting of furniture and decoration
- Construction: prefabrication of decorative features, pavement, paving stone, urban furniture. concrete casting
Advantages - Shore A from 10 to 30 hardness liquid mold rubbers
- Good fluidity and good operability and good for pouring method.
- Excellent mechanical properties, in particular tear strength and tensile strength.
- Excellent flexibility and it’s easy to demould.
- High temperature resistance, high duplication times and repeated use.
- Range of catalysts allows the M-20P to fulfill requirements for various applications: Curing agent fast cured of 2-7 hours
Thixo agent Thixotropic catalyst(brushing moldmaking)
Color paste Adjust different color of RTV-2 silicone

Pouring method is the best way because of good fluidity.
- M-25 / M-25P is for medium molds making. It’s also used for pouring method.
- M-30 / M-30P is applicable for large mold making since hard hardness. Both pouring and brushing method are ok.
