SMT-M550 is a 1-part, thixotropic silane-modified polymer sealant. It is fungus resistant and cures by reaction with moisture in the air to create an elastic coating against corrosion, UV and provides insulation. It can therefore be used for interior and exterior application on a wide range of substrate materials.


1.Fungus resistant.
2.Good protection against corrosion and UV light
3.Suitable for interior and exterior use
4.Provides good insulation
5.Suitable for a wide range of substrate materials
2.Sealing around bathroom fixtures and bathtub
3.Sealing along shower screen perimeters
4.Sealing around laundry area
