Brief description YJS-525 is medium hardness silicone with hardness Shore A 25. It is a kind of of two- component materials consisting of a flowable part A which when mixed with the curing agent or catalyst,cures at room temperature by a condensation recation. It is widely used for resin, gypsum, concrete/cement and artificial stone molding. Features -Easy to demould -Good resistance to tearing -Good elastic -Good tear&tensile strength -Dimensional stability in time ( deformation - shrinking only up to 0.3 % ) -Remarkable resistance to high temperatures (up to 200 - 220â?? ) -Final curing at room temperature Specification Typical general characteristics Inspection Method Value Product data (Catalyzed A+B) YJS-525 Hardness Shore A 25�±2 Mix Ratio A:B 100:2 Color / White Pot life 25 �°C (77F) 30-40mins Curing time 25 �°C (77F) 3-4 hours Mixed viscosity mPa.s 15000�±1000 Tear-strength kg/cm â?¥25 Tensile-strength M.pa â?¥4.2 Elongation % â?¥480 Shrinkage % â?¤0.3% Package * Small size:1kg/jar A +20gram/jar B, 12 jars in one carton.
