Surface elastic modulus of latex films studied with atomic force microscopy (AFM) and its correlation with dirt pick-up resistance (DPUR) performance

•Surface elastic moduli of coating films acquired by AFM are found to be probing rate dependent.•AFM and DMS results can be qualitatively compared by considering relative locations of the glassy and rubbery region.•AFM can obtain data on specimens that are not robust enough for DMS analysis.•Surface...
