Effect of phenyl silicone oil on room temperature cured silicone rubber

Effect of phenyl silicone oil on RTV silicone rubber first, the curing reaction of one-component RTV silicone rubber is to cure elastomer by interaction with moisture in air. With the different chain agents, one-component RTV silicone rubber can be deacidified, deoximed, dealcoholized, deamine, deamide and deketone. The curing time of one-component RTV silicone rubber depends on curing system, temperature, humidity and the thickness of silicone rubber layer. Under typical environmental conditions, generally 15 to 30 minutes later, the surface of silicone rubber can be no viscosity, 0.3 cm thickness of the adhesive layer in a day can be cured. The depth and strength of the curing will gradually increase in about three weeks. The vulcanization reaction of two-component RTV silicone rubber is initiated not by moisture in air, but by catalyst. Usually the rubber and catalyst are packed as a component respectively. Curing begins only when the two components are completely mixed together. The curing time of two-component RTV silicone rubber mainly depends on the type, amount and temperature of the catalyst. The more the amount of catalyst, the faster the vulcanization, and the shorter the shelving time. At room temperature, the use of time for a few hours, to extend the use of rubber, you can use cooling methods. It takes about one day for the two-component condensation type RTV silicone rafters to reach full cure at room temperature, but only one hour at 150 °C. The curing rate can be significantly increased by the synergistic effect of accelerants.
