CA 2454063
The invention relates to powder compositions hardenable by radiation usable for preparing paints and varnishes. These powder compositions contain an ethylenically unsaturated resin, a phosphorous containing compound and, eventually, a monomer or oligomer. The powder compositions of the invention are especially suited for coating over metal and combine upon melting at low temperatures and curing by radiation a series of properties such as good flow and film flexibility along with an outstanding adhesion to the substrate.
L'invention concerne des compositions pulvérulentes durcissables par rayonnement servant à la préparation de peintures et de vernis. Lesdites compositions pulvérulentes contiennent une résine à insaturation éthylénique, un composé contenant du phosphore, et éventuellement un monomère ou un oligomère. Lesdites compositions pulvérulentes sont particulièrement adaptées au revêtement de métaux et combinent par fusion à basses températures et durcissage par rayonnement une série de propriétés telles qu'un bon écoulement et une bonne flexibilité de pellicule ainsi qu'une excellente adhérence au substrat.
