Premium IV Pak-Free Asphalt

A Quality Controlled, Low Odor Hot-Melt Adhesive Packaged in Meltable Plastic Film

Premium IV Pak-Free Asphalt is designed for application as a thermoplastic hot melt adhesive in a variety of built-up roof configurations. The Pak-Free packaging helps reduce jobsite waste by eliminating asphalt keg containers and increasing the amount of asphalt that may be shipped per pallet.

Premium IV Pak-Free Asphalt is suitable for use as an interply adhesive for standard built up roofs, especially for steep-sloped roof applications.  In addition, it may be used as a flood coat surfacing adhesive for asphalt built-up and SBS modified bitumen roof systems, and is recommended for use to adhere Tremco Roofing-approved roof insulation boards to acceptable substrates.


Premium IV Pak-Free Asphalt consists of a high quality roof mopping asphalt processed from a closely monitored asphalt flux, and packaged in easy to handle polyethylene plastic wrappers.  A compatible low odor additive is blended within the hot melt to reduce jobsite odors.  Premium IV Pak-Free Asphalt meets tightly controlled performance characteristics and performs in accordance with ASTM D 312, the Standard Specification for Asphalt Used in Roofing.
