Ultraviolet rays (UV) combined with moisture can play havoc with the deterioration of an exposed surface. Exposed surfaces can include, but are not limited to; architectural structures, the exterior substrate of containment tanks, outdoor piping systems and roofs. The ultraviolet (UV) stabilization found in BaySystems protective coatings are an indispensable element of the BaySystems Protective Coating line. After application, the surface is protected from UV degradation and temperature variations.

When used as waterproofing components, these materials are capable of resisting hydrostatic pressure and are categorized as waterproofing materials.

The Bayblock protective coating line is offered in a variety of formulations, reflectivity and emissivity ratings and custom colors.

Bayblock (acrylics) are water-based elastomeric coatings widely used in BaySystems MAPS Program as a roof coating. They have earned the CRRC® rating due to their high reflectivity of harmful UV rays.

Bayblock coating is a single-component silicone elastomer specifically designed to protect roofs and construction surfaces from the effects of weather and moisture. Bayblock features outstanding high solids content , rapid cure time and superior physical properties.

Bayblock can be used by itself as the complete protective coating membrane or as a topcoat over a tough polyurethane elastomer basecoat for maximum life expectancy on a roof assembly. With the addition of ceramic roofing granules embedded into the coating surface, superior abrasion resistance is achieved.
