EternaPrime® is an adhesive and surface conditioner intended to aid adhesion of EternaBond® MicroSealant tapes, or other non- MicroSealant tapes such as butyl tapes and other self adhesive seaming tapes. EternaPrime® is also an excellent primer for use with self-adhered modified bitumen membranes. Use EternaPrime® when surfaces to be bonded are very dirty (oxidized and cannot be easily cleaned), or dusty (like on a tar and gravel roof). EternaPrime® will prepare the surface by coalescing all loose particles into a solid platform for the EternaBond® tape to adhere to. EternaPrime® allows EternaBond® MicroSealant® tapes to be installed in temperatures as low as -20°F (-29°C). EternaPrime® also prepares most contaminated surfaces for tape application.
