Sealant is a sealant for the first purpose of sealing, types are: silicone sealant, polyurethane sealant, polysulfide sealant, acrylic sealant, anaerobic sealant, epoxy sealant, butyl sealant, neoprene sealant, PVC sealant, and asphalt sealant.
There are two kinds of weather-resistant glue, one component and two components. The price of one component is much more expensive than that of two components. General domestic weather-resistant glue is a few yuan to twenty or thirty yuan, and the near mouth of weather-resistant glue is relatively expensive, generally 600ml packaging is about sixty to seventy yuan. Two components of domestic also have dozens of yuan a group, but the packaging is relatively small, generally will not exceed 1000ml/ group. A two-component version will cost at least twice as much.
Weather-resistant glue is mainly for the effects of ultraviolet radiation, ozone, rain, snow, sunlight, very low and very high temperature. There are mainly silicone, polyurethane components, polysulfide, rubber components and so on.
And glass glue mainly refers to silicone glue, its main use is for glass bonding. In addition to sticking glass, weather adhesive can also be used for other places, which will be exposed to the air and sunlight.

Weatherproof adhesive has adhesive and sealant, a long time by the sun, temperature change, wind and rain and other external conditions, will not appear fading, discoloration, cracking, powder and strength decline and a series of aging phenomenon. Ultraviolet radiation is the key factor. 【 the 】
