Blue Seal is a glass-filled modified hi-tech epoxy in which the inherent toughness of the modified epoxy has been enhanced by the addition of chemical-resistant C glass platelets.

Blue Seal’s hi-tech modified epoxy’s primary function is being a protective coating to resist corrosion, cavitation, electrolysis, abrasion and impact damage.

Tensile strength measures the amount of tensile or stretching stress a material withstands before breaking or failing. The glass fibers in Blue Seal are key to its excellent tensile strength, as they will stretch under pressure up to 14,500 psi / 1,109 kg/cm2 before breaking.

Flexural strength is a measure of the pressure a material will withstand before bending to the failure point. Blue Seal will bend even further than it stretches, which provides further resistance to damage.

Shore D hardness indicates resistance to indentation. Blue Seal’s hardness value of 88.2 indicates a very strong resistance to damage caused by direct impact relative to its flexural strength.
