Tin/Condensation silicone rubber for mold making

33RTV2 condensation/tin cured soft silicone rubber(M-20P soft hardness,M-25P medium one,M-30P hard silicone)[1] ApplicationsMoulds for thesmall production of parts in various materials( plaster, wax ,reconstituted stone, various resins(epoxy, acrylic, polyester), mortar, silicone elastomer ) such as:A. Decorative items: cornices, columns, ornaments, statues…..B. Figurines: toys, candles, statues, giftware, soap, craft projects, sculptureC. Furnishing: casting of furniture and decorationD. Construction: prefabrication of decorative features, pavement, paving stone, urban furniture. concrete casting[2] Advantages A. Shore A from 10 to 30 hardness liquid mold rubbersB. 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 the M-20 to fulfill requirements for various applications:Curing agent fast cured of2-7 hours Color paste Adjust different color of RTV-2 silicone[3] Data of RTV-2 Silicone rubberModel Color Viscosity Hardness (Mpa) Tensile Strength(Mpa) Tear Strength(KN/m) Elongation (%) Mixing ratio (%) Pot life (Min) Demould time (H)M-20Pwhite10000-1300020±2≥2.8≥2.0≥4002 510-302 7M-25Pwhite17000-1900025±2≥3.0≥2.5≥4002 510-302 7M-30Pwhite24000-2900030±2≥3.6≥2.7≥4202 510-302 7[4] The differences of M-20P,M-25P,M-30PA.M-20P 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.M-25P is for medium size molds making. It’s also used for pouring methods. The hardness is 25 shore A.C.M-30P is applicable for large mold making since hard hardness. Both pouring and brushing method are ok. The hardness is 30 shore A.If you need more information about RTV-2 silicone rubber,please feel free to contact with Ms Sherry at the number of 0086-755-27125425 and mobile 0086-15014058045.Welcome to visit www(dot)china-silicon(dot)net anytime.
