| abstract |
The present application relates to the field of sealants, and specifically discloses a hybrid cross-linked two-component hollow sealant. The hollow sealant includes a main sealing component and a curing component. The main sealing component includes 50~60 parts of hydroxyl-terminated polydimethylsiloxane, 30~40 parts of inorganic filler, 5~10 parts of dimethyl silicone oil, modified 2~5 parts of silicone oil, 1~3 parts of ethyl orthosilicate, 0.4~0.6 parts of water; curing components include: mixed crosslinking agent 25~35 parts; coupling agent 10~15 parts; organic tin catalyst 0.5~0.8 The main sealing component and the curing component of the two-component hollow sealant of the mixed cross-linking system are packaged separately. When using, the main sealing component and the curing component are mixed in a volume ratio of 8~10:1. The hybrid cross-linking system two-component hollow sealant of the present application can be used for sealing double-layer glass, and has the advantages of short surface drying time, that is, fast curing speed and high curing strength. |
