SIGMADUR 1800THE NEXT GENERATION DURABLE FINISHES
•Improved performance qualities•Differentiation in specification position
•Higher gloss stability•Better corrosion resistance•Higher dft’s•Economical improvements•Lower VOC
ADDED VALUE TOPCOATS

SIGMADUR 1800
Major driving forces in the Protective Coating industry:
Highly durable systems• Corrosion engineers and coating specifiers in the offshore and O&G industry ask
systems with a durability up to 20 years.• Coating suppliers have launched Polysiloxane topcoats with an expected durability of 15-
20 years.
Environmental issues.• Polysiloxane systems meet the latter requirement of being high solid hence reducing
VOC emissions
3
•Highly corrosive environments with high salinity and UV exposure (C5-I and C5-M). • Difficult accessible areas for maintenance or in case shut down costs for
maintenance is high.
USAGE OF HIGHLY DURABLE SYSTEMS:
4
TYPICAL SYSTEMS IN THE MARKET
•Two coat systems with zinc silicate or zinc rich epoxy as first coat.•Three coat systems.
ATTRACTIVE BENEFITS OF 2-COAT SYSTEMS
• Higher cost easily offset by savings in labour and time to contractors.• Projects of short time period to complete application.• Project end-users are inclined specifying coatings that will last longer.
5
HOWEVER
•Severe coating failures with a Polysiloxane topcoat reported after 2-5 years in offshore.•The main damage is a breakdown of the Polysiloxane topcoat in a two-coat zinc epoxy /
Polysiloxane system where dft. and stripe coating requirements were not met.•A combination of internal stress, lack of flexibility and decreased adhesion are considered to be the possible cause of failures.•Generally Polysiloxane technology has not proved to provide a risk free technology for 15-20 years service.•Polysiloxane show a wide difference in formulations, hence have different properties differ widely in performance,•Products with proper qualifications a proven history are available on the market.•Where toughness and flexibility beyond the yield point of steel is required, polyurethane coating provide better services.

FLEXIBILITY?
Hard coatings•Reduced friction damage•Abrasion resistant•Follows steel elongation
Flexible coatings•Reduced transport damage•Abrasion resistant (tough)•Follows bended or dented steel
