Preparation and Properties of Two-Component Condensed Transparent Silicone Sealing glue
Component A was prepared by α,ω-dihydroxypolydimethylsiloxane,dimethyl silicone oil and hydrogen silicone oil,and component B was prepared by dimethyl silicone oil with crosslinking agent,silane coupling agent and catalyst.Then component A and B were mixed at a mass ratio of 10∶1 to prepare two-component room temperature vulcanized(RTV-2)silicone sealing glue.The effects of different active hydrogen silicone oil on the properties of RTV-2 silicone sealing glue were studied.The results show that when the active hydrogen is 0.36wt%and the amount is 3 g,the sealing glue has the optimal performance,which can meet the requirements of waterproofing and bonding for LED.
