Safety:
Handle with care. Before and during use, observe all safety labels on packaging and paint containers,consult HEMPEL Safety Data Sheets and follow all local or national safety regulations.

SURFACE PREPARATION:
According to specification.

APPLICATION CONDITIONS:
Apply only on a dry and clean surface with a temperature above the dew point to avoid condensation.
Minimum temperature for curing is: -10°C/14°F.
At the freezing point and below be aware of the risk of ice on the surface, which will hinder adhesion.
The film formation may be adversely affected by light rain, high humidity and/or condensation during application and the following interval after application: 24 hours , 20°C/68°F.
In confined spaces provide adequate ventilation during application and drying.

PRECEDING COAT:
According to specification.

SUBSEQUENT COAT:
None.

REMARKS:
Colours/Colour stability:
Colour stability for some shades may be effected by exposure to harsh chemical atmospheres. This does not affect the performance of the coating.
For certain colours (yellow, red, orange, green, etc.), extra coats may be necessary to obtain full opacity.

Weathering/service temperatures:
At service temperature above 100°C/212°F, slight discolouration may be expected. The product will become softer.

Application(s):
When specified as a one coat “Direct to Metal”-system follow “Good Painting Practise” and apply stripe coating before the spray application on areas difficult to cover properly by spray application.
CURING AGENT 97050 : is sensitive to moisture. Even small traces of water in the mixed paint will reduce the pot life and result in film defects.
Film thicknesses/thinning:
May be specified in another film thickness than indicated depending on purpose and area of use. This will alter spreading rate and may influence drying time and overcoating interval. Normal range dry is:minimum 50 micron/2 mils (diluted), minimum 75 micron/3 mils (undiluted), maximum 125 micron/5 mils.

Curing agent:
Open curing agent cans with caution as overpressure might exist.
