Seal Trust™ Seam Tapes are a butyl sealer used for bonding various roofing membranes together in typical seam applications in the roofing industry. Long term heat and chemical resistance give Seal Trust™ EPDM Seam Tapes the ability to remain flexible in harsh conditions. Surpassing the industry standards for tack and shear strength our Seam Tape products provide superior holding power for long life and high durability. Used with typical roofing membranes such as EPDM, and TPO and some PVC membranes, Seam Tape allows for quick installation without expensive hot air welders. Industry standard roofing membrane cleaners and primers must be used to clean the membrane before application.
