Benefits of 1 component

• No end of potlife will reduce stress for the

applicator in difficult to reach areas

• No mixing errors
• No waste
• Less cleaning of pumps
• Simplifies paint locker

Hardtop One curing mechanism

• Cures with air humidity (comp.B)
• Lower limit of relative humidity will

be arround 30%

• Annual average Dubai 60% RH
• Chemically crosslinking

− Chemical resistance − Hardness

Tested at low temperatures

• Tested in artic conditions as Jotuns test

facilities in Svaldbard

• Cures down to 0°C

Rheology

• Rheology is important to control

workability, flow and sag resistance

• f a coating
• Rheological properties can be

adjusted according to the usage area

• f the coating (e.g. airless spray

application, brush and roller application etc.)

• The rheology profile in Hardtop One

has been carefully tuned to be brush and roller friendly
