WATER-BASED COMPOSITIONS WITH LONG TERM GLOSS RETENTION

Water-based coating compositions or paint having improved gloss retention, including a latex or water-dispersible polymer, a UV-VIS absorber comprising a substituted benzophenone capable of being a free radical generator, a hindered amine light stabilizer, and optionally a low-VOC coalescent provided in a preferably desired amount. A composition comprising a blend a UV-VIS absorber comprising a substituted benzophenone capable of being a free radical generator, a hindered amine light stabilizer, and a low-VOC coalescent, providing a thermally-stable coalescent that can be used in a paint formulation for gloss retention. Gloss retention of paints containing the UV-VIS absorber and hindered amine light stabilizer being markedly improved over paints that do not have both components present.

Method and device for producing a rubber mixture in a liquid phase

A process and device continuously prepare a filled rubber masterbatch. The process comprises bringing into contact, in a mixing zone, a first liquid-phase flow and a second liquid-phase flow, the first flow being an elastomer emulsion, the second flow being an aqueous suspension of filler particles, such that one of the two flows emerges inside the other flow and that the two flows are transported at low pressure before they are brought into contact.
