View / Download PDF Data Sheet
The protection of fabricated aluminum components such as Swim Platforms, T-Tops, Electrical Boxes, Poling Platforms, Fuel Tanks, Hand & Bow Rails, Windshield, Door, & Hatch Frames utilized on ocean craft boats requires the utmost consideration.
While anodizing is the most common choice for protection, it is not always aesthetically appealing. Additionally, corrosive salt will attack the anodized surface, and it will eventually exhibit pitting and oxidation, if not constantly cleaned or polished.
Marine Shield™ is a partially fluorinated powder coating, specially developed to protect aluminum components from the corrosive saltwater environment. Cured polymeric coatings have low permeability to oxygen, moisture, and salt ions, thereby mitigating corrosion.
Partially fluorinated powder coatings provide better resistance to UV (Sunlight) degradation, resisting chalking, fading, and loss of gloss, unlike inferior polyester powder coatings currently on the market.
Marine Shield has been used extensively over aluminum components in the saltwater environment for many years.

The maximum storage temperature for this coating is 80°F at 50% Relative Humidity. Under these conditions, a shelf life of 12 months is expected.
Availability:
This product line is available only to pre-approved coating applicators with substantiated quality control programs, including the pretreatment of the aluminum substrates. Custom color matching services are available.
Customer Line Surveys:
Crosslink Powder Coatings can tailor these products to your coating line. To do so, our skilled associates must perform a coating line survey, to include monitoring of the oven times and temperatures. Please advise if you would like this service.
Precautions:
All dusts are respiratory irritants. The coating area must be properly ventilated and oven air exhausted to the outside environment. If skin contact occurs, immediately wash with mild, soapy water. If eye contact occurs, flush with water immediately and secure medical attention. Dust clouds of any finely divided organic material can be ignited by electrical sparks or open flames. All equipment must be electrically grounded to preclude buildup of static electricity. Dust collection equipment must be provided for adequate exhaust of dust-laden air.
