Invisible Shield® Glass Coatings – The “Easy Clean” Marine Glass Solution “That Beats All Elements”.
Boats, motor yachts, cruise ships, naval fleets, and offshore vessels face some of the most demanding glass maintenance conditions on earth. Constant exposure to salt spray, oxidation, humidity, minerals, and harsh weather quickly degrades unprotected glass surfaces — reducing visibility, increasing maintenance costs, and accelerating surface wear.
Maintaining marine glass often requires large cleaning crews, elevated platforms, robotic cleaning equipment, heavy chemical usage, frequent freshwater rinsing, and continuous restoration cycles. For large vessels exceeding 50,000+ square meters of glass, this becomes a major operational expense.
Unelko’s Nano-Scale Invisible Shield®, Invisible Shield® PRO 15, and REPEL® Cleaner & Repellent create a durable molecular barrier that protects marine glass and surfaces from salt and salinity buildup, mineral deposits, oxidation and corrosion, water spotting, environmental staining, and surface degradation.
These coatings are ideal for bridge and cockpit glass, exterior windows and curtain walls, balustrades and railings, skylights and atriums, glass partitions, shower doors and mirrors, deck enclosures, observation areas, elevator glass, and interior and exterior glazing.
Reduce Cleaning Costs and Improve ROI
Invisible Shield® dramatically reduces cleaning frequency, labor hours, chemical consumption, equipment use, restoration cycles, and surface replacement costs. This delivers exceptional return on investment across fleets and marine facilities.
Proven in the Marine Industry
Invisible Shield® coatings are trusted by major marine operators including Disney Cruise Line, Carnival Cruise Line, Princess Cruises, Royal Caribbean, and Norwegian Cruise Line, as well as leading glass manufacturers including AGC, Saint-Gobain, Vitro, Oldcastle, and Guardian.
Trusted Performance for Over 50 Years
With more than 50 years of proven performance, Unelko supports cruise lines, naval fleets, shipbuilders, marine contractors, glass fabricators, and maintenance providers worldwide. Invisible Shield® delivers long-term clarity, lower maintenance costs, and superior protection in the harshest marine environments.
Invisible Shield® Marine Coatings provide long-term glass protection, reduced operational costs, improved vessel appearance, enhanced safety visibility, and a sustainable maintenance solution. Treat once, clean less, and protect marine glass for years.
Glass Restoration for Existing Glass
Although a vast amount of the existing glass worldwide has already been permanently stained, etched, damaged or obscured, all is not lost! The Invisible Shield Coatings will stop the degradation and corrosion of existing, unprotected glass in the field. It can turn costly, hard to maintain glass into better looking, protected, easier to maintain glass.
Unelko manufactures a number of products to pre-clean and restore glass. The products are highly efficacious and provide an effective cleaning system to remove stains before applying the Invisible Shield protection.
Based on 3rd party tests conducted by international testing organization, Nanovea, that utilize ASTM standards, G99, D7027 and D7187, Unelko’s Invisible Shield Coatings are proven to be:
- 23% more resistant to wear than uncoated or untreated glass
- 92.9% more resistant to scratch penetration
- 31.2% less stress on coated glass compared to uncoated due to greater resistance to scratch penetration
