ARMOURLAY PLUS OBS 60

SURFACE PREPARATION

The surface should be thoroughly cleaned and dried using a hot compressed air lance

operating at 800 - 1000°C to remove any dust, laitance and loose foreign matter.

APPLICATION

The material shall be loaded into a preheating mixer fitted with positive temperature control

and mechanical agitation and raised to it’s application temperature of 190 ± 10°C. Apply the

material using a screed box with a suitably designed trailing edge to give an applied

thickness not exceeding 3mm and a width not exceeding 40mm (HD31/94 Part 1).

On an average textured surface, the application rate for OBS 60 is approximately

4500lm/Metric Tonne

ARMOURLAY PLUS OBS 60 presents no acute health hazard at ambient temperature.

However as these materials are normally handled at elevated temperatures when their

physical state changes to a liquid, the bitumens present in these products give off fumes

which are undesirable to inhale as small quantities of Hydrogen Sulphide are be present in the bitumen. Please refer to the Product Safety Data Sheet for further information.

SAFE HANDLING PRECAUTIONS

· Do not exceed the maximum safe heating temperature.

· Do not allow the hot material to come into contact with water as the product will

react violently.

· Always wear the recommended protective clothing.

RECOMMENDED PROTECTIVE CLOTHING

Overalls, Goggles/Visor, Gloves and Closed Safety Boots when handling hot products.
