        SILICONE RUBBER FOR SHOE MOLD APPLICATION:
            Shoe mold silicone rubber is a kind of liquid RTV two-component silicone rubber, part A is liquid silicone base, part B is curing agent. They will room temperature vulcanization after adding catalyst into silicone base.
            Add curing agent of 2%-5% to liquid silicone at the condition of room temperature, stir the mixture evenly, then pour or brush the liquid mixture to the mother mold, then after 2-6 hours, a flexible silicone rubber mold will be obtained
        Generally, there are two molding methods for shoe molding: pouring molding, brushing molding.
         

        SILICONE RUBBER FOR SHOE MOLD INSTRUCTION :
        1. The amount of the curing agent depends on the actual requirements of customers. If molds requiring fast drying and demould, more curing agent is needed; contrarily, if molds require slower drying and demould, less curing agent will be needed.
         (Note: our company does not recommend that customers add silicone oil. If customers surely need quite soft silicone mold or molding for fine detailed and complex patterns products, 5%-10% silicone oil can be added to soften the mold for easy demoulding.)
         
        The proportions and reactions of the curing agent and the base silicone are listed as the followings:
          1. With 1% catalyst, the handing time is within 2.5 hours and silicone the mold can solidify after 8 hours.
          2. With 2% catalyst, the handing time is within 1 hour and the silicone mold can solidify after 6 hours.
          3. With 3% catalyst, the handing time is within 30 minutes and the silicone mold can solidify after 4 hours.
          4. With 4% catalyst, the handing time is within 15 minutes and the silicone mold can solidify after 2 hours.
        (Note: Above speculation is not fixed data, because we provide 5 types of catalyst with different curing speed)
