RTV-2 MOULD MAKING SILICONE RUBBER MATERIALS
RTV2 condensation/tin cured soft silicone rubber(XL-8810 soft hardness,XL-8820 medium one,XL-8830 hard silicone)
[1] Applications of rtv-2 silicone rubber
Moulds for the small production of parts in various materials (plaster, wax, reconstituted stone, various resins (epoxy, acrylic, polyester), silicone elastomer) such as:
A Decorative items: cornices, columns, ornaments, statues…..
B Figurines: toys, candles, giftware, soap, craft projects, sculpture
C Furnishing: casting of furniture and decoration
D Construction: prefabrication of decorative features, pavement, paving stone, urban furniture. concrete casting
[2] Advantages rtv-2 silicone rubber
A. Shore A from 10 to 30 hardness liquid mold rubbers
B. Good fluidity and good operability and good for pouring method.
C. Excellent mechanical properties, in particular tear strength and tensile strength.
D. Excellent flexibility and it’s easy to demould.
E. High temperature resistance, high duplication times and repeated use.
F. Range of catalysts allows to fulfill requirements for various applications:
Curing agent fast cured of 2-7 hours
Color paste Adjust different color of RTV-2 silicone
Color paste Adjust different color of RTV-2 silicone

[4] The differences of XL-8810, XL-8820, XL-8825, XL-8830 (HOW TO CHOOSE the most SUITABLE SILICONE RUBBER WHAT YOU WANT)
A. XL-8810 is mainly used for molds with small, delicated patterns. Pouring method is the best way because of good fluidity. The hardness is 10 shore A.
B. XL-8820 and XL-8825 is for medium size molds making. It’s also used for pouring methods. The hardness is 20 shore A and 25 shore A.
C. XL-8830 is applicable for large mold making since hard hardness. Both pouring and brushing method are ok. The hardness is 30 shore A.
