About Our Products
 Seal Pros, Inc. uses high quality, environmentally safe products from Seal Master.
We use only a particular mix design of coal tar with Black Beauty Sand and a latex additive. A mix we have perfected over the last ten years to ensure the longevity of your investment.
Below is more information excerpted from the National Pavement Contractor's Association regarding the two primary types of sealcoating materials on the market: Those made from refined coal tar and those made from asphalt.
Refined coal tar "a byproduct of the coking process" is a very complex mixture of thousands of chemicals and quite different in its molecular structure than asphalt. Sealcoatings based on refined coal tar were introduced in the 1950s and have been used extensively to protect off-street pavements. These often are referred to as Coal Tar Pitch Emulsions (CTPE), denoting that these coatings are water based, obtained by dispersing refined coal tar in a matrix of clay and water. The CTPE incorporates the protective features of refined coal tar and the reinforcing effect of mineral fillers, to offer a "barrier coating" that will flex with the pavement's movements while protecting the asphalt from the destructive elements of weather, gas, oil, fat, chemicals etc.
Asphalt emulsion based coatings have been introduced in recent years with varying degrees of success. In fact, many sealer manufacturers that previously produced only refined coal tar sealers now also produce asphalt-based sealers or even asphalt/refined coal tar blends. The asphalt emulsions deliver most of the same properties as refined coal tar-based coatings --except for the resistance to color fading due to ultraviolet degradation, salts, and petrochemicals like oils, fats, grease and solvents. Being a petroleum derivative, asphalt has a natural affinity for petrochemicals, so it is easily dissolved by them. This is important considering that we know that these chemicals often leak, spill, or are washed onto driveways.
