Protective Coatings One component polysiloxane topcoat Morten Martinsen & Lasse Isaksen Hardtop One

Protective Coatings Hardtop One in a nutshell 1 component polysiloxane topcoat with 2K preformance Isocyanate free NORSOK compliant No mixing and no waste High volume solids (72%) Low VOC 190 g/l ( IED 2010/75/EU) Hardtop One

Protective Coatings 1 component polysiloxane topcoat with 2K preformance Same quality, just simpler Traditional 2 Component Hardtop One

Protective Coatings 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

Protective Coatings Tested at low temperatures • Tested in artic conditions as Jotuns test facilities in Svaldbard • Cures down to 0 ° C Hardtop One

Protective Coatings Rheology • Rheology is important to control workability, flow and sag resistance of a coating • Rheological properties can be adjusted according to the usage area of 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 Hardtop One

Protective Coatings Rheology Jotun polysiloxane topcoats Designed for airless spray application • Hardtop Pro • Hardtop Optima • Hardtop One During Resting After application, condition application viscosity build up Hardtop One

Protective Coatings Excellent hiding power by brush and roller Brush application Roller application Edge covering Hardtop One

Protective Coatings Photo from the Brage platform show excellent hiding power in one coat by brush and roller Hardtop One

Protective Coatings Spray application Hardtop One can also be applied with airless spray and conventional spray Hardtop One

Protective Coatings Summary • 1 component with 2 component performance • No mixing errors • Reduced consumption and waste • Excellent UV resistance (gloss retention) • Cures down to 0 ° C • NORSOK compliant Hardtop One
