RTV-2 Silicone Rubber for PU moldmaking

[1] RTV-2 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 molding 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 whichfeatures with resistance to deformation, high-temperature, acid-alkali and expansion.[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-2P5,M-30P A.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.[5] RTV-2 silicone rubber instruction:RTV-2 molding silicone rubber are generally named as two-part room temperature sulfuratedsilicone rubber, which features an exceptional fluidity and good operability. When mixedwith 2-5% curing agent, they can still be operated within 30 minutes, but will be formedafter 2-7 hours. With resistance to deformation, high temperature, acid and alkali, andexpansion, silicon flexible molds are used for mold duplication and delicate mold making forpoli crafts, resin crafts lighting and candle crafts.Any further information required ,pls feel free to contact Miss Sherry.TEL: +86-755-27125425Mobile: +86-15014058045Welcome to visit www(dot)china-silicon(dot)net and call for any time.
