Joint Sealer 525
Single component polyurethane sealer
JOINT SEALER 525 is a thixotropic, solvent free,
moisture curing sealant. It is a filled system that
has moisture and oxidation resistance and
exhibits good adhesion to cementitious and
steel substrates.
Applications
- JOINT SEALER 525 can be used as a general joint sealer and crack filler on cementitious surfaces. It provides medium chemical, wear and corrosion resistance, while at the same time curing to a 25 Shore A hardness (+/- 5 Shore A). A degree of colour change with time is to be expected. It is not recommended for use in water retaining structures.
