GSB-88 EMULSIFIED SEALER/BINDER - Ip ri4 3 SPECIFICATION Product Description: GSB-88 Emulsified Sealer/Bindcr is a chemically engineered asphalt pavement sealer/binder comprised of a cationic emulsion of Gilsonite Ore, and specially selected plasticizers. This chemical colloid stabilized emulsion has been specifically formulated for sealing asphalt parking lots, city streets, county roads, airport taxiways, and airport patking aprons. GSB-88 provides a durable, yet flexible top coat, while special plasticizers and oils penetrate and rejuvenate asphalt pavements. The result is an emulsified sealer/binder that restores vital components to asphalt pavements lost during the aging and oxidation process. The gilsonite seal provides a long wearing anti-oxidative seal for the surface of the asphalt pavement. GSB-88 beautifies asphalt pavements by drying to an absolute black color. Specifications: GSB-88 is available in either a concentrate or ready to use form. The concentrate form allows large shipments via tank truck or railroad tank car. The concentrate form must be diluted with water prior to application.
