GRC Mold Silicone Rubber

GRC Mold Silicone Rubber Description:   GRC mold silicone rubber is liquid bicomponent silicone rubber,which includes part A and pare B,part A is flowable liquid silicone rubber,part B is vulcanizing agent,the silicone can form quickly after mixing.Whether condensation cure silicone rubber or addition cure silicone rubber,both of which are suitable to product and duplicate GRC products,the former is industrial silicone rubber with the ratio of 100:5,the latter is food grade silicone rubber with the ratio of 1:1 or 10:1.   GRC Mold Silicone Rubber Application:   GRC mold silicone rubber is suitable for architecture,decoration mold making,such as GRC European-style decorative components,plaster line,plaster waistline,architecture decoration,backdrop,art stone,roman column,human statue,garden cement sculpture,statue,rocks,weathered stone,slate mold making.   GRC Mold Silicone Rubber Features: 1.Clear pattern,delicate textures,good simulation effect especially for artificial stone mold making. 2.Lower shrinkage to avoid a waste of silicone mold. 3.High tension and tear strength,non-deformation. 4.High duplication times,more durable,acid and alkali resistance. 5.Easy-operation,time-saving and labor-saving.   GRC Mold Silicone Rubber Operations: According to the mode of operation,the opening modes of mold are pour mold,brush mold and envelope.     Hong Ye Silicone Rubber---GRC Mold Silicone Rubber Datasheet of HY-640:   Model HY-640 Appearance liquid Hardness(shore A ) 40±2 Mixing ratio(%) 2-3 Viscosity(mPa.s) 15000±2000 Tensile strength(MPa) 3.5 Tear-strength(kN/m) 21±2 Elongation(%) 400 Shrinkage rate(%) 0.3 Operation time(mins) 30-50 Curing time(hrs 25℃) 4-5     GRC Mold Silicone Rubber Notes: 1.The amount of catalyst should depend on temperature,Higher temperature,less addition. When the curing agent is used too much, the mould will be hard and brittle. When the curing agent is used too little, the operation time will be prolonged.   2.In order to use silicone mold the most effectively,please use it after checking at least 24 hours.
