Sealant is a sealing material that deforms with the shape of the sealing surface, is not easy to flow, and has a certain degree of adhesion. It is usually based on dry or non-drying viscous materials such as asphalt, natural resins or synthetic resins, natural rubber or synthetic rubber, and then includes inert fillers, and then adds plasticizers, solvents, curing agents, accelerators And so on. The sealant is distinguished by its performance. The single-finger function is sealing. The weather-resistant adhesive, silicone structural adhesive, and polyurethane adhesive all have sealing effects, but have other important functions, such as high bonding strength and good weather resistance.
