Differences between MS polymer sealant and polyurethane sealant:

MS modified silane adhesive, also known as Ms modified silane structural adhesive, is a one-component or two-component elastic sealant made of MS polymer as the basic polymer, with fillers, plasticizers and other functional additives. The curing method is mainly hydrolysis and dealcoholization of silane and moisture in the air and condensation. It belongs to moisture absorption curing adhesive.

Polyurethane sealant is a one component environmental friendly plastic glue composed of organic isocyanate (- NCO) and polyester containing hydroxyl (- OH) at the end. It is an elastic sealant prepared by polyurethane prepolymer, filler, plasticizer and other functional additives. The product type is one component or two-component. An elastomer is formed by reacting isocyanate with water in the air or other active hydrogen containing compounds.
