Good price condensation cure 2 parts rtv silicone rubber for mould making 1.Description: YJS-520 is a high tear strength, tin-catalyzed RTV-2 silicone rubber, which was designed for casting polyester parts. It offers the same advantages of lower viscosity.YJS-520 is especially good for molds with deep undercuts and for molds that require flexing for part removal.YJS-520 is not sensitive to inhibition, meaning it will cure at room temperature over virtually any surface. It is easy to mix and de-air, and will cure with only a slight degree of shrinkage. The speed at which the rubber hardens can be accelerated with special activators. Condensation cure two-component silicone rubbers are excellent for most general mold making and prototype applications. They are excellent for casting waxes, gypsum, epoxies and other plastics. YJS-520 is extremely useful for those applications where superior elongation and medium durometer are required. 2.TechnicalDatasheet Productdata Inspection Method Value(YJS-520) Hardness ShoreA 20±2 MixRatio A:B 100:3 Color / White Potlife 25°C(77F) 30-40mins Curingtime 25°C(77F) 3-4hours Mixedviscosity mPa.s 16000±1000 Tear-strength kg/cm 20±2 Tensile-strength M.pa 3.6±0.5 Elongation % 400±50 Shrinkage % ≤0.3 3.Characteristics ＊An exceptional fluidity and good operability, easy to demold ＊A kind of soft silicone ＊Good tensile strength and tear strength ＊Cure at room temperature ＊Good flexibility ＊Outstanding bubble releasing ＊Good duplication times 4.Package Small size: 1 kg/jar, 5 kg/jar, 10 kg/jar General size: 20 kg/pail, 25 kg/pail, 200 kg/pail ♦ Delivery Time Depends on the express you choose and the destination Via Express:General 3-7 business days worldwide ♦ Shipping Cost Based on the weight of the goods and the destination ♦ Tracking No. The tracking No. will be sent to you the next day after shipping 5.SHELFLIFE: Whenstoredatorbelow32°C(89.6°F)intheoriginalunopenedcontainers,YJS-5seriesSiliconeBaseanditsCuringAgentshaveausablelifeofI0months.
