Single component, polyurethane, liquid waterproofing membrane.
Sikalastic-618 is a single component, cold-applied, moisture-triggered polyurethane membrane. It cures to form a seamless, durable and weather-resistant waterproofing solution for exposed roof areas.
J31/353 Waterproof coating
Standard product features
One-component moisture-triggered aromatic polyurethane.
Sikalastic-618 waterproofing membrane is seen to resist attack from a broad range of dilute acids, alkalis, salt solutions, and organic solvents. In service, this protection is seen to cover exposure to most aggressive environments that may be encountered such as acid rain, traffic pollutants (such as vehicle fumes, petrol, oil, ethylene glycol), sea water, decaying vegetation and industrial atmospheres where higher levels of ground level ozone may be encountered. However, stronger acidic solutions and lower molecular weight alcohols are seen to damage the coating. Accordingly, for applications combining long term roof protection with increased resistance to specific reagents.
