PRODUCT DATA SHEET

POLYFLEX TYPE 2

PART NO. 34518

JANUARY 2002

READ BEFORE USING THIS PRODUCT

GENERAL Crafco PolyFlex Type 2 is a single component, hot-applied, petroleum based product which is used to seal and fill cracks and joints in both asphalt and portland cement concrete pavements in warm climates. PolyFlex Type 2 is supplied in solid form which when melted and properly applied forms a highly adhesive and flexible compound that resists cracking in the winter and is resistant to flow at summer temperatures. PolyFlex Type 2 can be used in highway, street, airfield and parking lot pavements. It should be applied to pavement cracks using pressure feed melter applicators. At application temperature PolyFlex Type 2 is a medium viscosity product which flows and penetrates cracks. PolyFlex Type 2 is formulated as an economical yet effective pavement maintenance crack filling product. Compared to products based on reclaimed rubber, PolyFlex Type 2 offers lower viscosity for easier application, improved summer temperature pick-up resistance, quicker set times, and improved low temperature flexibility.

SPECIFICATION CONFORMANCE The Crafco recommended specification limits for PolyFlex Type 2 when heated in accordance with ASTM D5078 to the safe heating temperature are as follows:

APPLICATION The unit weight of Crafco PolyFlex Type 2 sealant is 10.0 lbs. per gallon (1.20 kg/L) at 60°F (15.5°C). Prior to use, the user must read and follow Application Instructions for Hot Applied RoadSaver, PolyFlex and Asphalt Rubber Products (January 2002) to verify proper product selection, heating methods, pavement preparation procedures, application geometry, usage precautions and safety procedures. These instructions are provided with each pallet of product.

PACKAGING Packaging consists of individual boxes of products which are palletized into shipping units. Boxes contain a non-adherent film which permits easy removal of the product. Each pallet contains 72 boxes which are stacked in six layers of 12 boxes per layer. The weight of product in each box does not exceed 40 lbs. (18kg) and pallet weights do not exceed 2,880 lbs. (1310 kg). Pallets of product are weighed and product is sold by the net weight of product. Product boxes are manufactured from double wall kraft board producing a minimum bursting test certification of 350 psi (241 N/cm2) and using water resistant adhesives. Boxes use tape closure and do not contain any staples.

Boxes are labeled with the product name, part number, lot number, specification conformance, application temperatures and safety instructions. Palletized units are protected from the weather using a three mil thick plastic bag, a weather and moisture resistant cap sheet and a minimum of two layers of six month u.v. protected stretch wrap. Pallets are labeled with the product part number, lot number and net weight. Application Instructions are provided with each pallet in a weather resistant enclosure.
