Increased Elasticity

Blue Seal has an incredible 12% elasticity which makes Blue Seal 12 times more flexible than typical hull coating products. Elasticity is very important in a hull coating system because movement and vibrations cause typical hull coatings to crack and peel. Blue Seal’s elasticity allows it to absorb energy from impact thereby decreasing the likelihood of coating failure. Blue Seal’s flexibility will out flex aluminum and in fact, upon impact with aluminum substrate, combined with its adhesive strength, the substrate will yield before the Blue Seal will de-bond.

Superior Resistance to Mechanical Stress

Tensile strength is vital for an effective hull coating system because most products don’t have
strength to add anything to the base metal. Blue Seal’s high tensile strength of 16,000 to 19,000 psi combined with its superior adhesive strength can help add strength back to a pitted or corroded hull. This high tensile strength also prevents marine growth from damaging the coating system.

Unlike paint products which contain a binder and a high percentage of fillers to make it cheaper to manufacture, Blue Seal contains no fillers and has an extremely tight molecular bond. The tight cross-linking makes Blue Seal impervious to vapor transmission.

Chemical Resistance

Blue Seal can easily take double salinity salt water at boiling temperatures with no vapor transmission. Blue Seal is so corrosion resistant that, even for submersion duty, it will protect steel from extremely harsh chemical solutions like 35% hydrochloric acid, 78% sulfuric acid or pure sodium hypochlorite. Compared to the extreme chemical environment that Blue Seal was designed to handle salt water is a non-taxing application. Blue Seal’s extreme protection insures that the hull will be protected for decades as opposed to paint systems that have to be reapplied every few years.

High Dielectric Strength

Unlike other epoxy paint systems, Blue Seal is an excellent dielectric insulator offering
sprayable cathodic protection. Each mil of Blue Seal will withstand 600 volts. This means that at 40 mils of coating thickness, Blue Seal will insulate the hull from over 20,000 volts without coating failure or electrolysis damage to the hull. Because of Blue Seal’s high dielectric strength it is commonly used as a dielectric shield around the anodes on ships that use an impressed current system. Protection from electrolysis is just one more level of protection that Blue Seal offers the ship owner over other coating products.

Hull Scrubbing Advantage

Because of its high strength, Blue Seal may be scrubbed mechanically using nylon bristles without causing damage to the coating system or the hull. Hull scrubbing on a regular interval can add up to huge fuel savings. According to published US Navy studies the average pay back on a hull scrubbing in fuel savings is just 12 days at sea.

Reduce Maintenance Costs

Blue Seal drastically reduces maintenance costs by reducing the workload and the time spent in dry-dock as well as eliminating the labor and material cost of repeatedly sandblasting and coating the hull with typical paint systems. The combination of Blue Seal and hull scrubbing also adds up to huge savings in fuel consumption while eliminating tons of marine pollutants that would be dispersed into the oceans.
