Minyu Li, Robert D P Hei, Mark D Levitt, Lauren K Carlson: Jobsite-renewable multilayer floor finish with enhanced hardening rate. Ecolab, IPLM Group P A, May 5, 2009: US07527861 (3 worldwide citation)

A jobsite-renewable multilayer floor finish system has an undercoat employing a first hardening system, an autohardenable (e.g., two-part) topcoat employing a second hardening system, and at least one initiator for the topcoat hardening system in at least the undercoat. The initiator increases the t ...

Mark D Levitt, Minyu Li, Lauren K Carlson, Robert DP Hei: Aqueous polyurethane coating system containing zinc crosslinked acrylic dispersion. Iplm Group Pa, July 14, 2005: US20050153139-A1

Zinc crosslinked acrylic dispersions can initiate hardening of 2K polyurethane coatings based on polyester polyols or polyurethane polyols and decrease the coating tack-free time. The decreased tack-free times facilitate earlier application of additional polyurethane layers and earlier return of a c ...
