Abstract of  CN105586001 (A)：

The invention discloses a low-viscosity high-transparency self-adhesive organic silicone pouring sealant and a preparation method thereof. The preparation method includes the steps of feeding polydimethylsiloxane with terminal vinyl groups, vinyl MQ silicone resin, polymethylhydrosiloxane, an adhesion promoter, 1-acetenyl-1-cyclohexanol and a Karstedt catalyst into a high-speed dispersing machine, and mixing the components uniformly to prepare the low-viscosity high-transparency self-adhesive organic silicone pouring sealant. The pouring sealant is higher than 96% in light transmittance, is good in flowability, is easy to use, can be cured at normal temperature or under heating conditions, has good adhesion and mechanical performance, and can be widely used in the fields of optical devices, LED chip potting and the like with high requirements on transparency and adhesion strength.
