Why Sealcoat?

Rochester Jet-Blak coal tar sealer is a heavy-duty refined coal tar sealer that is specifically designed to protect bituminous pavements. Composed of high temperature refined coal tar pitch, select mineral fillers and surfactants, Rochester Jet-Blak coal tar sealer forms a tough, durable and flexible coating that protects asphalt pavements from the damaging elements of weather, water, salts, gas and other petro-chemicals.

Appearance
The dark charcoal black color of Rochester Jet-Blak coal tar sealer improves the appearance of new and old asphalt pavements. Unprotected asphalt surfaces gradually lose their rich black color due to oxidation and weathering. Rochester Jet-Blak coal tar sealer preserves the smoothness and resilience of asphalt surfaces and helps hide rough spots, small cracks, patches and surface depressions. Pavements coated with Rochester Jet-Blak coal tar sealer look cleaner because rainfall washes dirt and debris easily from the smooth, non-porous surface. Traffic lines become more visible.

Resists Fuel Penetration Resists gas, oil, salt and chemical penetration. Asphalt is a petroleum derivative, soluble in distillates such as gas, jet fuel and oil drippings. Rochester Jet-Blak coal tar sealer prevents damage from distillates and chemicals.

Prevents Water Penetration The intrusion of moisture into asphalt pavement structure accelerates its deterioration and is strongly related to pavement distress. The sealing of well-cured asphalt with Rochester Jet-Blak coal tar sealer prevents the seepage of moisture from snow and rain, thus preventing damage from freeze-thaw cycles.

Stops Oxidation Actinic rays in sunlight can oxidize the asphalt oils in pavement, causing brittleness and a resulting loss of aggregates which may rob up to 50% of the original asphalt thickness in just five years. A pavement sealcoated with Rochester Jet-Blak coal tar sealer will resist oxidative degradation and retain its value. Reduces cost and increases value Rochester Jet-Blak coal tar sealer substantially reduces maintenance costs and at the same time, extends the life of asphalt pavements by as much as 300%. The cost of Rochester Jet-Blak coal tar sealer is truly a minor expense when compared to the cost of pavement replacement. Rochester Jet-Blak coal tar sealer also greatly extends the life of existing sound pavements.
