Elastic Sealant
MS1980 is a one-component sealing adhesive based on high-performance silane-modified polymers, which reacts with moisture in the air to form an elastic rubber body after the paste comes into contact with air. The product's applicability and curing speed are related to the temperature and humidity of the environment. The curing speed significantly accelerates in high-temperature and high-humidity environments, while low-temperature and low-humidity environments will delay the curing process.
MS1980 has high modulus and good resilience, making it suitable for elastic bonding and sealing of various materials under general conditions. It has excellent aging resistance and can permanently maintain adhesion in natural environments.
