MS200 Elastic Sealant
MS200 is a single component sealant based on MS polymer. It will react with moisture in the air and gradually cure into elastic rubber after exposed. The curing speed of the sealant is related to the ambient temperature and humidity. The curing is accelerated in high temperature or high humidity environment, while the process will be delayed in low temperature or low humidity. The final curing time is also related to the thickness of the sealant.
