Despite a reputation for causing paint film defects, even polydimethylsiloxane-hydrophobed silica antifoams can also apparently find use in waterborne latex paints if certain preventive measures are applied (see, e.g., reference [28] and Section 9.3.2). It is tempting then to infer that, despite the complexity of waterborne latex paint formulations, the conventional oil-hydrophobed particle antifoams listed in Chapter 4 (Tables 4.A1 through 4.A3) find ready application in fhis context, albeit with additional components such as emulsifiers designed fo ease dispersal or structurants to ensure stability of the stored antifoam against sedimentation. Practical experience then implies that the rupture of foam films confaining high volume fractions of latex polymer particles by conventional antifoams is readily achieved. [Pg.487]

Figure 15.2 Examples of 2D layers fabricated by convective assembly, [a] Examples of a crystal monolayer obtained from 1.1 jam PS latex particles. The crystalline order leadingto bright diffraction is revealed when illuminated with a white light from behind. [b) SEM images of a 100 nm gold nanoparticles monolayer assembled on a silicon surface (unpublished results], a monolayer (c], and a bilayer (d] obtained with 500 nm PS particles. The structures were first assembled on a flat PDMS substrate and then transferred onto a silicon wafer by printing. Abbreviations SEM, scanning electron microscopy PDMS, polydimethylsiloxane PS, polystyrene.

The efforts to synthesize waterborne hybrid polymer-polymer nanopartide dispersions are due to the expected synergetic behavior of the positive properties of each polymer phase. Hybrid latexes made of alkyd resins, " polyurethanes, polydimethylsiloxane (PDMS), polyester,"" ... [Pg.476]
