This rubbing may cause a smoother, glossier surface at the contacted area, depending on the level or type of pigments in the paint and binder hardness. This method permits a more quantitative estimate of burnish resistance than those using manual rubbing techniques. A weight of 600 g was used and the gloss was measured after 20, 50, and 100 passes.

All Rights Reserved 3M Advanced Materials Division Conclusions Addition of W-410 3M™ Ceramic Microspheres considerably increases the performance of an acrylic water-based paint, thus increasing the paint’s quality. Addition of 5% by volume of W-410 to a water-based acrylic paint formulation with PVC of 40%, yields the best performance Higher loading of 15-20 percent by volume of W-410 3M™ ceramic microspheres is possible when increasing the PVC content to while reducing the amount of resin, and yet still exhibits a higher performance when compared to the baseline formulation which has no W-410. Viscosity did not increase dramatically when high loadings of W-410 were added to the water based paint formulations in this study. 35 © 2013 3M. All Rights Reserved 3M Advanced Materials Division Considerations High loadings (10-20% by volume) of W-410 may be possible to add to a baseline water-based flat architectural paint with PVC of 40%, if the majority of its fillers are substituted with W-410 ceramic microspheres; as is the case of formulas DG-5 and DG-6 in this study Addition of W-410 Ceramic Microspheres with low to medium loading (2.5-10% volume) slightly decreases opacity in a flat architectural paint; as compared to the baseline paint formulation with no ceramic microspheres added and similar PVC content Higher loadings (10-20 percent) of W-410 will increase opacity, as the PVC increases, even if other fillers are present in very low amounts. 36 © 2013 3M.

Stronger glass bubbles improve scrubability more than lower strength bubbles. Glass bubbles do not improve washability over conventional fillers. Glass bubbles decrease gloss more than smaller ceramic microspheres. 47 © 2013 3M. All Rights Reserved 3M Advanced Materials Division Part 2: Cost-in-use of Glass bubbles 48 © 2013 3M.

All Rights Reserved 3M Advanced Materials Division Part 4: Solar reflectivity with Glass Bubbles 68 © 2013 3M. All Rights Reserved 3M Advanced Materials Division On the outside of a structure, solar radiation dominates. To prevent the heating of a surface by the sun, the first step is to reflect as much of the solar radiation as possible. Thus the first goal is to have the visible and near and IR wavelengths reflected as completely as possible (0.28 to 2.5 μm ). The solar radiation that is not reflected is absorbed by the surface. At that point, the absorbed energy is in the form of heat near room temperature. (That heat can either conductively transfer into the structure, or it can be re-emitted to the atmosphere. Since the heat is now at near-room temperature, we need a high thermal wavelength (2.5to 40 μm ) emissivity to effectively re-emit as much as possible back to the atmosphere. In summary, for an exterior surface, the goal is high solar wavelength reflectivity and high thermal wavelength emissivity. 69 © 2013 3M.
