What’s manual mold design silicone rubber ?

Manual mold design silicone rubber is a flowable liquid, and the quality has nothing to do with the color.It consists of two component.Part A is a flowable liquid silicone rubber,part B is the curing agent.Manual mold silicone belongs to RTV-2 Silicone Rubber.It is suitable for manual mold design and small duplication mold production which has good elasticity,non-deformation,high temperature resistance,low shrinkage.   　　Manual mold design silicone rubber is mainly used for model design of manual mold, PVC plastic molds,cement products,low melting point alloy molds,alloy toys, plastic toys,electronics,handicrafts,stationery,large-scale sculpture, reproduction of cultural relic,shoe sole molds,pad printing allocation, Electronic equipment antivibration,and so on.   　　What’s the operation Instruction of manual mold silicone?Firstly,after your previous work of dealing with the original model,take some liquid silicone rubber,add 2%-3% curing agent of the amount of silicone,and mix them evenly. Then after vacuum-pumping the mixture,you can pour it into the mold frame.The silicone mold will cured in 2-3 hours.   　　By the way the time for vacuum-pumping should be less than 3—5 mins ,otherwise,once the silicone rubber has cross-link reaction during vacuumizing, it will not be operated.
