Sealant - Polyflex Type 4



GENERAL

Crafco PolyFlex Type 4 sealant is a hot-applied, asphalt based product used to fill cracks in asphalt or Portland cement concrete pavements in very hot climates. PolyFlex Type 4 is supplied in solid form which when melted and properly applied forms a stiff, adhesive and flexible compound that bonds strongly to pavement cracks and is highly resistant to tracking or pick-up of vehicle tires in hot climates. Polyflex Type 4 is used in highway, street, airfield and parking lot pavements and is applied to pavement cracks using pressure feed melter applicators. At application temperature, PolyFlex Type 4 is a medium viscosity product which flows and penetrates cracks. PolyFlex Type 4 is formulated as an economical yet effective pavement maintenance crack filler product. Compared to products based on reclaimed rubber, PolyFlex Type 4 offers lower viscosity for easier application, improved summer temperature pick-up resistance, quicker set- up times and improved lower temperature flexibility.
