Presenting a new solvent-based polymer surface treatment designed for superior adhesion enhancement when combined with NP-8400 primer and liquid polyurethane on a variety of cured vulcanized and thermoplastic materials. This treatment serves as an initial coating to elevate surface energy before applying NP-8400 primer. A snapshot of possible materials includes natural rubber, SBR, nitrile, EPDM, neoprene, PU, and select plastics.
