SOPRASEAL SEALANT is a solvent-free and low VOC, moisture cure polyether sealant (STPE) and contains no isocyanates.
SOPRASEAL SEALANT has elastomeric properties which provide good flexibility and excellent adhesion to most construction materials as well as SOPRASEAL membranes .
SOPRASEAL SEALANT is used as a waterproofing complement for wall application and can be used as a termination sealant as well as to fill and repair horizontal and vertical voids of concrete and masonry substrates that do not exceed 13 mm (1/2’’) in width.
This product can be used on most substrates such as aluminum, metal, concrete, masonry and plastics including PVC.
The substrate must be clean and dry. Debris and other contaminants such as water, grease and oil may compromise the adhesion. Metal surfaces and PVC pipes must be cleaned with non-greasy solvents, such as acetone or methyl ethyl ketone (MEK).
Apply SOPRASEAL SEALANT with caulking guns. Initial curing time varies from 30 minutes to an hour with complete cure after 24 hours depending on temperature and relative humidity.
Application temperatures: above 0°C (32°F)
Service temperatures: -40°C to 93°C (-40°F to 200°F)
