Self-cleaning coatings

Номер: US20120010314A1
Принадлежит: University of Western Ontario

The present invention provides two methods for synthesizing novel titania-polyurethane (nTiO 2 -PU) nanocomposites for self-cleaning coatings, one a polymer functionalization method (“grafting to”) and the other, a monomer functionalization method (“grafting from”). Here, 2,2 bis(hydroxymethyl) propionic acid (HMPA) was used as the coordination agent, which was reacted with n-TiO 2 (50:50 anatase/rutile) to form nTiO 2 -HMPA, then polymerized in the monomer functionalization method. In the polymer functionalization method, HMPA was reacted with a pre-polymer to form the PU, and then subsequently reacted with n-TiO 2 to form the polymer nanocomposite. The photocatalytic cleanability of the nanocomposites was investigated when exposed to ultraviolet radiation using additional unreacted HMPA or stearic acid as the model “dirt” compounds. Nanocomposites prepared using both strategies showed similar self-cleaning behavior, although the monomer technique gave less substrate degradation.

Hot curing or heat-activated composition containing a surface-deactivated polyisocyanate

Номер: US20120012251A1
Принадлежит: SIKA TECHNOLOGY AG

The present invention relates to curable compositions comprising at least one specific blocked amine, at least one surface-deactivated polyisocyanate that is solid at ambient temperature and optionally water or a water-producing substance. Compositions of this type are characterized by an extremely high storage stability as long as they are not heated. Hot curing compositions that cure with the action of heat can thus be produced. Heat-activated compositions can also be produced. When heat is applied the latter compositions are not cured but are activated so that they are able to cure under the influence of moisture. The curable compositions are particularly suitable for use as adhesives.
