General Crafco Superflex is a hot-applied asphalt based product used to seal and fill cracks and joints in asphalt or portland cement concrete pavements in moderate to cold climates. Superflex is supplied in solid form which when melted and properly applied forms an adhesive and flexible compound that resists cracking in the winter and is highly resistant to flow and pick-up at summer temperatures. Superflex can be used in highway, street, airfield and parking lot pavements and is applied to pavement cracks and joints using either pressure feed melter applicators or pour pots. At application temperature Superflex is a free flowing, self-leveling product. Superflex can be melted in jacketed double boiler type melting units or in small direct bottom fired type melters. Both types of melters must have sufficient agitation and temperature indicating devices to assure that the sealant is heated to and maintained within the specified application temperature range of 380 to 400°F (193 to 204°C). VOC = 0 g/l.
Crafco Superflex meets the following requirements when heated to the maximum heating temperature in accordance with ASTM D5167:
