HOW IT WORKS
The vinyl-ester base of Blue Seal is inherently chemical resistant. Vinyl-ester is similar to the polyester used in fiberglass resin, with styrene as the active ingredient. The key difference is that the polyester links only at the ends of the molecule chain, while vinyl-ester zippers the entire chain together along its full length which provides excellent physical strength.
Reacted epoxy monomers are added to the resin to provide elasticity and adhesion strength which the vinyl-ester lacks by itself.
Chemical resistant glass platelets are then combined into the mix to provide a unique wafer board type construction which creates side bonds rather than edge bonds. The resin surrounding the platelets provides flexibility, while the glass platelets act as a thermal barrier to prevent cracking.
The resulting coating mixture is immune to corrosion as it is non-metallic, immune to cavitation because it is a cross-inked polymer, and immune to electrolysis because it is a dielectric insulator.
Prevent Penetration Through Coating
The glass platelets in Blue Seal are flat, and ensure up to 3/16” square and 3 to 4 microns thick. Unlike spherical of fibrous strands, 30 to 40 mils of coating will contain 150 to 200 overlapping layers of platelets to form a formidable barrier against any type of liquid, gas vapor, oxygen or chemical penetration.
