Elastic sealing glue
MS1970 is a single-component sealant based on high-performance silane-modified polymers. It gradually hardens into a rubber-like elastomer upon contact with air and reacts with moisture in the air. The curing speed of the adhesive paste is related to the temperature and humidity of the environment; high temperature and high humidity accelerate curing, while low temperature and low humidity delay this process. Ultimately, the curing time is also related to the thickness of the adhesive paste.
