Liquid elastic sealant: this type of sealantsinclude the sulfide formation elastic State ofliquid polymer. They have joints under repeateddeformation capacity. Liquid elastomer seal life for 15-20 years. This type of sealant with highadhesive shear strength at room temperature andhas good flexibility. Its disadvantages for highprices usually need two-component adhesivesealant mixed inconvenient curing temperatureand humidity-sensitive, and so on.
