What are MS polymer sealants?

MS polymer sealants are a type of sealant made from a hybrid of silane-modified polymer and polyether. 

They are often referred to as hybrid polymer sealants and were formulated to combine the characteristics of silicone and other sealant types, such as polyurethanes. 

MS polymer sealants, also known as “Modified Silicone” or Hybrid sealants, use a modified silane polymer as their base instead of the synthetic polymer base of silicone or the urethane-based polymer system utilized by polyurethane sealants.
