Silicon AstraZeneca (Room Temperature Vulcanization) two component room temperature silicone rubber mold referred RTV-2 molding silicone rubber. This is a two-component compound. It is the flow at room temperature, as long as the appropriate amount of curing agent ( catalyst) compound in the presence of two sets of cross-linking reaction catalyst; formed with flexible; resilient colloid; therefore suitable for glass resin (POLYSTER) epoxy resin (EPOXY), Pu foam resin, plaster, cement, candles, electronics and other process plant toy factory; Electronic factory; lighting plant; silk screen factory; candle factory; production of decorative crafts and replication products; manufacture of molds.
Easy molding operation; easy to master technology; silicone just add 2%; curing agent 7-15 minutes; can be gelled (coking) 45-60 minutes can mean dry; plastic surface tack; could release; as curing put increasing doses (usually no more than 4%) gel time and stripping time will be shortened. Also based on product and process requirements appropriate to add 5% -10% silicone mold better, pay attention to silicone should not be raised too much, otherwise Effects of glue tension and hardness of the product of the technical indicators:
Resistance to burn 150-250
25-27 degree tear-resistant
Resistance Rally 1-4
Less resistance to expansion of ± 5 ‰
Turning model number 200-300
Molding silicone rubber due tasteless, non-toxic, not spontaneous, so transportation convenient storage, unregulated Packing: 25 kg drum
