HYPERDESMO® Classic is a one component polyurethane fluid which cures with the humidity in the atmosphere. It produces a very strong membrane with outstanding adhesion to many types of surfaces and excellent chemical and hydrolysis resistance properties.
Ideal for protecting metal structures against corrosion. Suitable for chemicals and effluent treatment tanks and sewage tubes. It is highly resistant to gases produced during waste water treatment, e.g. methane, hydrogen sulphide etc.
Apply with brush, roller or airless spraying in one or two coats with maximum consumption per coat of 150 gr/m2. Thinning is not necessary.
When exposed to sunlight, directly or indirectly, HYPERDESMO® Classic has the tendency to discolour (yellowing). To preserve colours, a protective topcoat of HYPERDESMO®-ADY-E (always pigmented) is required.
