Sikalastic® M 678
(former MSeal M 678)
Rapid curing, chemical resistant, elastomeric waterproofing membrane
Sikalastic® M 678 is a solvent free, two component, high performance polyurea hybrid based waterproofing membrane, with high resistance to common chemicals. Using a specially designed spraying machine, the two components are pre- heated and spray applied, to a rapid curing, elastomeric, waterproofing membrane.
- Fast reacting - Rapid installation. Does not run when applied on vertical surfaces
- Seamless - No risk of leaky seams and laps.
- Spray applied - Fast installation on large surfaces; easy application on complex details.
- Fully bonded - Eliminates water collection behind membrane even if punctured.
- High tensile strength - Excellent ability to accept movements without rupturing.
- Elastomeric - Excellent crack-bridging ability.
- High tear resistance - Minimised risk of damage to membrane in service.
- Low Tg (Glass Transition Temperature) of -20˚C - Remains elastomeric at very low temperatures. Performance unaffected in below freezing conditions.
- Solvent-free - Improved safety.
- Potable water contact approved – suitable for tanks containing drinking water
