Embodiment 1

[0007] A well-cured sealant formula. The raw materials in the formula are composed by weight percentage: 75% of base polymer, 1% of petroleum resin, 1% of silicon micropowder, 5% of fumed silica, 1% of filler, and 11% of catalyst , 5% plasticizer, and 3% coupling agent. At this time, the curing speed of the well-cured sealant is relatively slow, and the curing effect is not good.

Embodiment 2

[0009] A well-cured sealant formula. The raw materials in the formula are composed by weight percentage: 85% of base polymer, 5% of petroleum resin, 10% of silicon micropowder, 15% of fumed silica, 5% of filler, and 19% of catalyst , 7% plasticizer, and 5% coupling agent. At this time, the well-cured sealant cures faster and the curing effect is not good.

Embodiment 3

[0011] A well-cured sealant formula. The raw materials in the formula are composed by weight percentage: 80% of base polymer, 3% of petroleum resin, 5.5% of silicon micropowder, 10% of fumed silica, 3% of filler, and 15% of catalyst , plasticizer 6%, coupling agent 4%, at this time the well-cured sealant has good curing ability and curing speed.
