Description of the shape of the seal related sealant

The liquid elastomer sealant sealant comprises a liquid polymer which is vulcanized to form an elastic state. The seal members have the ability to withstand repeated seam deformation, and the liquid elastomer sealant generally has a service life of 15 to 20 years. This type of sealant has high adhesion and shear strength with good flexibility at room temperature. The disadvantage is that the price is high. Under normal circumstances, it is necessary to use a two-component sealant for in-situ mixing, which is inconvenient to be sensitive to temperature and humidity during vulcanization. Sealant paste sealant is a low-grade sealant which usually adopts three main materials. Oil and resin polybutene pitch.
   Commonly used for sealing small windows, the fixed movement of the joint is up to +5% or -5%. The effective period is usually two years. The seal liquid sealant is mainly used for the sealing of the mechanical joint instead of the solid seal. Material paper, asbestos, cork and vulcanized rubber to prevent mechanical internal fluid from leaking from the joint surface. Liquid sealant is also called liquid gasket. Sealant hot melt sealant is also called hot construction sealant. The blend is a base sealant. Hot melt sealants can be formulated to be close to liquid elastomeric sealants but superior to liquid elastomer sealants in that they do not require the addition of a vulcanizing product.
