About this file
This is a product data sheet for Crafco PolyFlex Type 2 crack sealant prepared for the Maryland Aviation Administration's procurement of paving maintenance materials for BWI Airport. The document provides comprehensive technical specifications and performance characteristics for the hot-applied, asphalt-based sealant product, which is used to fill cracks and joints in asphalt or Portland cement concrete pavements in moderate to hot climates. PolyFlex Type 2 is supplied in solid form and melts into a highly adhesive and flexible compound suitable for use on highways, streets, airfields, and parking lot pavements. The product is applied using pressure feed melter applicators and has been in production for over 25 years, with several states having developed specifications based on its performance. The sealant meets or exceeds multiple ASTM standards, including cone penetration, resilience, softening point, ductility, flexibility, flow resistance, viscosity, and tensile adhesion requirements, with a minimum application temperature of 380°F and maximum heating temperature of 400°F.
PolyFlex Type 2 has a unit weight of 10.5 pounds per gallon and zero volatile organic compound (VOC) content. The product is packaged in either cardboard boxes containing 30 pounds each (75 boxes per pallet, approximately 2,250 pounds total) or in meltable packaging with completely meltable blocks that eliminate cardboard disposal. All packaging is labeled in accordance with OSHA and GHS requirements, stored on 48 by 40 inch pallets with weather-resistant covers and UV-protected stretch wrap, and can be stored outdoors. Crafco warrants that products meet applicable ASTM, AASHTO, Federal, or State specifications at the time of shipment, with warranty claims requiring notification within three months of use or twelve months from delivery, whichever is earlier. Remedies are limited to product replacement or refund of the purchase price. The company recommends following all installation instructions provided with each pallet to ensure optimum performance and proper application procedures.

PRODUCT DATA SHEET
POLYFLEX TYPE 2
PART NO. 34518
DECEMBER 2022
READ BEFORE USING THIS PRODUCT
GENERAL
Crafco PolyFlex Type 2 sealant is a hot-applied, asphalt-based product used to fill cracks and joints in asphalt or Portland cement concrete pavements in moderate to hot 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 resists flow at summer temperatures. PolyFlex Type 2 is used in highways, streets, airfields, and parking lot pavements and is 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. PolyFlex Type 2 has been a quality Crafco product for over 25 years. Several states have developed specifications based on performance of PolyFlex Type 2. VOC = 0 g/l.
SPECIFICATION CONFORMANCE
The Crafco recommended specification limits for PolyFlex Type 2 when heated in accordance with ASTM D5078 to the maximum heating temperature are as follows:
Test Specification Limits Cone Penetration (ASTM D5329) 35-55 Resilience (ASTM D5329) 40% min.
Softening Point (ASTM D36) 200 °F (93 °C) min Ductility 77 °F (25 °C) (ASTM D113) 30cm min Flexibility, 1/8” (3.2 mm) specimen, 90° bend, 10 sec., 1” (25 mm) mandrel (ASTM D3111 Modified) Pass at 20 °F (-7 °C) Flow, 140 °F (60 °C), 5 h, (ASTM D5329) 3 mm max.

Minimum Application Temperature 380 °F (193 °C) Maximum Heating Temperature 400 °F (204 °C)
INSTALLATION
The unit weight of Crafco PolyFlex Type 2 sealant is 10.5 lbs. per gallon (1.26kg/L) at 60 °F (15.5 °C). Prior to use, the user must read and follow Installation Instructions for Hot-Applied RoadSaver, PolyFlex and Asphalt Rubber Products 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
Product is supplied in either cardboard boxes, or in meltable boxless packaging. Both package types are labeled in accordance with OSHA, GHS, and specification requirements; are sold by net weight; are interlock stacked on 48 x 40 in. (122 x 102 cm) 4-way pallets; can be stored outside; and are covered with a weather resistant pallet cover and 2 layers of UV protected stretch wrap.
o BOX packaging consists of cardboard boxes containing 30 lbs. (13.6 kg) of product with 75 boxes per pallet, weighing approximately
2250 lbs. (1020 kg). Boxes contain a quick melting release film for easy removal and are taped closed, without any staples.
o Meltable packaging consists of approximately 30 lbs. (13.6 kg) completely meltable packages that are interlocked stacked on pallets. To use, the pallet wrap is removed, and individual blocks are placed in the Melter. There are no individual cardboard boxes to open, empty, handle, or dispose of. Meltable packaging quickly melts into the product without affecting specification conformance. Meltable packaged sealant products are sold by the pallet only and individual packages are not intended for sale.
