Solvent-free phenolic epoxy – ultimate protection in extreme conditions

Specially designed to provide ultimate resistance

The PPG SIGMASHIELD 1200 coating is the latest development in reinforced, abrasion- and impact-resistant coatings designed specifically to be fit-for-purpose for ice-going service.

It is the newest generation of the highly successful solvent-free epoxy phenolic technology with proven anticorrosive properties and very high polymer cross-link density to enhance abrasion resistance. The product also boasts enhanced mechanical-, impact- and abrasion resistance outperforming market standard products in both key laboratory tests and in service.

Impact and abrasion resistance

The performance of the PPG SIGMASHIELD 1200 coating is as good – if not better – than existing systems. It is unquestionably superior in terms of gouge resistance (‘gouging’ being a potential cause of serious damage where intense pressure points are exerted on a ship’s hull as it moves through ice). The product’s excellent performance has been confirmed by Aker Arctic Technology, a major independent testing institution, which specializes in low-temperature testing at the limits of ice-going conditions.

The PPG SIGMASHIELD 1200 coating has also passed independent extreme low-temperature ice testing developed and conducted by a leading shipyard.


Anticorrosive protection

Under extreme conditions, no coating can provide 100% protection. A degree of damage is inevitable; the focus must be on minimizing this damage and, should the substrate be exposed, reducing subsequent coating damage. In contrast to other competitive systems benchmarked, the PPG SIGMASHIELD 1200 product exhibits excellent performance in combination with cathodic protection, significantly reducing the creep corrosion process from the damaged area.

Ease of application

Under normal conditions, the PPG SIGMASHIELD 1200 coating can be applied by cold, single-feed airless spray equipment, as opposed to the hot, twin-feed system specified and used by the benchmark technology. Available in standard- and low-temperature grades to broaden the application window, the product is suitable both for new-building block stage and dry dock application. As it is 100% solids and solvent free, the coating reduces overall VOC emissions as well as reducing the risk of fire and explosion. The PPG SIGMASHIELD 1200 product also conforms to the latest international environmental and safety standards.

Low friction

The smoothness of the PPG SIGMASHIELD 1200 coating is such that it has a lower frictional coefficient than the market standard. This means a vessel coated with this coating moves through ice with less frictional resistance, reducing fuel and engine load, and consequently saving costs.


Time to save – the ultimate cost saver

The PPG SIGMASHIELD 1200 product has been recognized and approved as an abrasion-resistant, low-friction ice coating by the international classification authorities on the basis of independent examination and testing.

“These values demonstrate the very low friction coefficient for PPG SIGMASHIELD 1200 in ice resulting in higher speed or lower fuel consumption compared to other hull coating systems.” Aker arctic technology

PPG SIGMASHIELD™ 1200: Bore Ltd, Finland

PPG Protective & Marine Coatings (PPG) offers two abrasion-resistant, ice coatings (PPG SIGMASHIELD 460 and PPG SIGMASHIELD 1200). These were selected based on the anticipated ice conditions during service life. The PPG SIGMASHIELD 1200 coating is based on a very hard filler composition, providing excellent anti-abrasion properties, and on a highly cross-linked phenolic epoxy technology, further extending the service life of the coating by tremendously increasing the creep resistance.

The B-Class vessels Balticborg and Bothniaborg operate between The Netherlands, Germany, Sweden and the UK to a tight schedule with very limited maintenance time. They also face severe ice conditions in winter, so the hulls need excellent, long-lasting protection to ensure reliable, economical performance levels. SIGMASHIELD 1200 was therefore specified to minimize damage, reduce subsequent repair costs and improve operational efficiency.

PPG Protective & Marine Coatings (PPG) convinced Boskalis, after 2 years of extensive testing both in-house and externally, that PPG SIGMASHIELD products would provide the most durable coating solution for cargo holds. PPG applied a system comprising the PPG SIGMASHIELD 1090 product as an under layer with the PPG SIGMASHIELD 1200 coating as a finish layer on top to the Causeway at the Shipyard Boer, Sliedrecht, The Netherlands.
