POLYTAR is different from federal. We pre add the different latexes to our tar prior to emulsification. This process makes the material tougher and more fuel resistant. POLYTAR also oxidizes less rapidly than a standard sealer and also bonds better to the pavement surface. In scrub test in our lab we have seen a 40% better wear with PT vs. standard coatings. If you have any further questions please feel free to call me at the office. 404 696 7660.
