GRC European-style Decorative Components Mold Sili

GRC European-style Decorative Components Mold Silicone Description:   GRC European-style decorative components mold silicone rubber is a kind of bicomponent silicone rubber,divided into condensation cure silicone rubber and addition silicone rubber,both of which are suitable for GRC European-style decorative components of silicone mold making,the former is industrial silicone rubber,the latter is food grade silicone rubber with environmental,non-toxic and tasteless.Part A is flowable liquid silicone,part B is vulcanizing agent.   GRC European-style Decorative Components Mold Silicone Application:   GRC European-style Decorative Components Mold Silicon is primarily intended for all kinds of GRC European-style decorative components and irregular shaped cultural stones molds making,such as art stone,cultural stone,window frame,door frame,plaster line,roman column,backdrop,architecture decoration,garden sculpture,rocks,weathered stone,slate,and so on.Especially better effect can be achieved after applying to artificial stones,it can replica the delicate textures of natural stones.   GRC European-style Decorative Components Mold Silicone Performance Requirements: 1.Can replica the delicate textures of natural stones,effective simulation,clear pattern and fine texture. 2.Easy-operation,save the labor cost. 3.Lower shrinkage,good tension,non-deformation. 4.High duplication times,more durable,acid and alkali resistance.   GRC European-style Decorative Components Mold Silicone Operations: 1.According to the mode of operation,the opening of the mold are envelope,brush mould(split mould,solid mould,plane mould),pour mould. 2.The 25 shore A,30 shore A or 40 shore A of silicone hardness are suitable for pouring mould making:   The hardness of 25 shore A and 30 shore A mold silicone are suitable for medium and small size crafts with moderate hardness.   The hardness of 40 shore A mold silicone is suitable for large size products with high hardness.   Common features: low viscosity,good fluidity,easy-operation,release bubbles easily,high tension and tear strength,easy to pour. 3.The 30 shore A,35 shore A or 40 shore A of silicone hardness are suitable for brushing mould making:   The hardness of 30 shore A mold silicone is suitable for medium and small size crafts.   The hardness of 35 shore A and 40 shore A mold silicone are suitable for large size products.   Common features: moderate viscosity,uneasy flowing,brush easily,high tension and tear strength.   Hong Ye Silicone Rubber---GRC European-style Decorative Components Mold Silicone Datesheet:   Model HY-630 HY-E630 Appearance Liquid Liquid Hardness(shore A) 30±2 30±2 Mixing ratio(%) 2-3 1:1/10:1 Viscosity(mPa.s) 27000±2000 9000±2000 Shrinkage rate(%) 0.3 0.1 Tensile strength(MPa) 4.0 5.2 Tear strength(kN/m) 26±2 12±2 Elongation(%) 420 470 Operation time(mins) 30-40 20-40 Curing time(hrs 25℃) 3-4 3-5   GRC European-style Decorative Components Mold Silicone 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.
