“…They exhibit lower water resistance, [5,6] a tendency to whiten in moist atmospheres, and lower tack, adhesion and shear strengths. [7,8,9,10] On the positive side, polymer colloids offer a facile means to tailor the structure of adhesive films at the nanometer length scale [11]. Nanostructured particles have been used to create films with remarkable mechanical properties.…”

“…There is a much smaller body of work to correlate the molecular architecture and nanostructure of waterborne colloidal films with their adhesion properties. [15,16,17,18] In waterborne PSAs, the distribution and migration of small molecules, especially surfactants, [7,9,19] has been correlated with poor waterborne adhesive performance and is of special interest. Greater understanding of surfactant distribution normal to the film surface has been obtained recently from modelling [20] Published in Journal of Colloids and Interface Science (2007) 307, 56-63 5 and experiment [21].…”

Abstract. Tackifying resins (TR) are often used to improve the adhesive properties of waterborne pressure-sensitive adhesives (PSAs) derived from latex dispersions.There is a large gap in the understanding of how, and to what extent, the film formation mechanism of PSAs is altered by the addition of TR. Herein, magnetic resonance profiling experiments show that the addition of TR to an acrylic latex creates a coalesced surface layer or "skin" that traps water beneath it. Atomic force microscopy of the PSA surfaces supports this conclusion. In the absence of the TR, particles at the surface do not coalesce but are separated by a second phase composed of surfactant and other species with low molecular weight. The function of the TR is complex.. According to dynamic mechanical analysis, the TR increases the glass transition temperature of the polymer and decreases its molecular mobility at high frequencies. On the other hand, the TR increases the molecular mobility at lower frequencies and thereby promotes the interdiffusion of latex particles to create a skin layer.In turn, the skin layer is a barrier that prevents the exudation of surfactant to the surface. The TR probably enhances the coalescence of the latex particles by

“…Holl et al [3][4][5][6] identified many factors that govern the concentration of surfactant at the polymer-substrate interface, including the polymersurfactant, polymer-substrate-surfactant, and surfactant-water interactions. Extensive research was previously performed on the polymersurfactant interactions between diglycidyl ether of bisphenol A epoxy cured with 2-ethyl-4-methylimidazole (EMI-24) with a nonionic surfactant Triton X-100 additive.…”
