    • Disclosed herein is a one-component sealant compound being based on a silicone-modified polyether polymer having methyl dimethoxysilyl functional groups on ends of a polyproylene oxide main chain, which is blended with a plasticizer, a filler, an adhesive additive agent and a curing catalyst, as well as a meta/acrylic component prepared by dissolving a copolymer of two or three of ethyl acrylate, propyl acrylate, butyl acrylate, methyl methacrylate, butyl methacrylate and lauryl methacrylate in a solvent and an amine component prepared by dissolving a solid long-chain primary or secondary saturated monoamine or diamine having a melting point in a range of 40 to 100°C in a solvent. The meta/acrylic component and the amine component migrate to the surface of the sealant in a curing process at a higher speed than the plasticizer to form a barrier film layer on the surface, thereby preventing the same from surface pollution.
