ClearShield® Protection for Marine Glass is Tough as Diamonds!

Diamond Princess is a British-registered cruise ship owned and operated by Princess Cruises. She has the distinction of being the first ever Princess Cruises ship to be built in a Japanese shipyard, specifically the Mitsubishi Heavy Industries (MHI) shipyard in Nagasaki. Whilst there, the ClearShield System® was used to renovate and protect 12,000m2 of glass, ensuring it is stain-resistant, easy to clean and keep clean and ultimately looking like new for longer.

The ClearShield System® application was carried out by Ritec International’s Marketing Partner in Japan, TBKK (Toa Boeki Kabushiki Kaisha) in 2004, under the supervision of Stefan Roelands, Ritec’s marine application specialist based in the Netherlands. Specialist after-care products were recommended to prolong the service life of ClearShield®, and these were used by maintenance teams.

By chance late last year, Mr Junji Nozaki, TBKK’s Managing Director, came across the Diamond Princess whilst docked in Yokohama. Junji observed the glass, particularly the cabin windows and balustrade panels, and all were looking sparkling clean. He has no doubt that ClearShield® is still doing its job, even after an amazing 15 years, keeping the glass looking as good as new with reduced maintenance requirements.

Diamond Princess is a prime example of everything great about ClearShield®:

  • The System renovates and protects the glass, upgrading it to a superior, ‘non-stick’ easy-clean surface;
  • ClearShield® protection is durable despite constant exposure to harsh conditions;
  • using the recommended after-care products prolongs the life of ClearShield®, significantly reducing costs and delays from having to replace badly-stained glass;
  • the glass looks cleaner for longer which in the cruise ship industry, means fewer complaints from passengers who cannot enjoy nice seaviews due to heavy staining on the glass.

Durable ‘non-stick’ ClearShield® protection for glass is proven in the marine sector and others too, including architectural, residential, decorative, offshore, shower and food & hygiene. For more information, visit
