![]() ![]() Canadian crude oil has different characteristics from Venezuelan crude oil, for example, and those differences will show up in a finished asphalt emulsion sealer. Geoff Crenson, Bonsal American, says there are more variations in asphalt than there are in coal tar products because properties in asphalt can vary much more widely than the industry has experienced in coal tar. "It might be produced for some type of road application or it might be produced for something else, but it's never produced to any specification for pavement sealer." "First of all, the material sealer producers buy to make asphalt-based pavement sealers is not produced with that purpose in mind," says Tim Vance, president of Vance Brothers. Manufacturers agree that the first thing contractors need to realize is that 100% asphalt-based sealers are very different from coal tar sealers. On the other hand, companies such as Western Colloid, Asphalt Coatings Engineering, Raynguard Protective Materials, and Blacklidge Emulsion all base their pavement sealing products - blends or not - in asphalt-based materials.Īll those interviewed for this article made it clear that their comments were not to be applied directly to any or all products available on the market, but should be applied generally to each category of product as a type of pavement sealer. Bonsal American produces all three products, as does GemSeal, SealMaster, Star Inc., Surface Coatings Co., and Vance Brothers Asphalt Mfg. only offers a blended product to contractors if coal tar is hard to come by. produces both coal tar sealer and asphalt-based sealer, but sells the asphalt-based sealer to retailers in 5 gallon pails and coal tar emulsion to contractors in bulk. Neyra Industries, for example, produces both a coal tar sealer and an asphalt-based sealer but does not produce a blended product. If they want an asphalt-based sealer we'll produce that for them."īut not all sealer producers produce all types of product. "If the contractors want a coal tar sealer and we can get the raw materials, we'll produce a coal tar sealer. "We're a coatings manufacturer and we will make coatings out of whatever quality materials are out there that we can get," Conwell says. In response to this uncertainty, many sealer producers are taking the approach outlined by Joe Conwell, vice president of sales for Neyra Industries. ![]() Other products, such as asphalt/coal tar blends, and material containing ceramics are also available, so sealcoating contractors have a variety of options to choose from if the coal tar they prefer becomes scarce. In the recent past producers have sought to broaden the types of sealer materials available to the market, with asphalt emulsion-based products being the primary alternative. ![]() Already sealer producers are reporting significant price increases, but of greater concern to contractors is the availability of the coal tar sealer. As sealcoating contractors begin their season many of them, particularly those accustomed to using refined coal tar sealer, wonder what the season will hold for their favorite product. ![]()
