  • Patent number: 8735466
    Abstract: The present invention relates to a film forming composition comprising a resin and modified nanoparticles comprising nanoparticles and adsorbed thereon a segmented copolymer, preferably a segmented blockcopolymer, comprising an adsorbing segment and a hydrophobic surface active segment, wherein the adsorbing segment has one or more functional groups that adsorb on the nanoparticles and wherein the hydrophobic segment is more hydrophobic than the resin providing surface migration of the nanoparticles. The invention also relates to novel modified particles and the use of the specified segmented copolymer of specified modified particles in a film forming composition for imparting thereto improved surface properties such as scratch resistance.

  • Patent number: 8029899
    Abstract: The invention relates to coated particles comprising particles and a crosslinked polysiloxane coating and to a process for the manufacture of said coated particles. Further, the invention relates to the use of the coated particles to improve surface properties of articles and to material compositions comprising the coated particles, in particular coating compositions. According to the invention there is provided coated particles comprising particles having a surface with hydroxy functional groups and a crosslinked polysiloxane coating comprising a reaction product of polysiloxane disilanol according to formula I: wherein n is 1 to 25, and wherein each R is a same or different hydrocarbon group, and a coating crosslinking agent, preferably an alkoxysiloxane having 3 or 4 alkoxy groups which polysiloxane coating is at least partly grafted to the particle surface by reaction with the hydroxy functional groups on the particles.

  • Patent number: 7790236
    Abstract: The invention relates to a high gloss car wash-resistant coating composition comprising an epoxy-functional binder and a cross-linker reactive with the epoxy groups of the binder and a method to prepare such a car wash-resistant coating. The invention further relates to the use of said coating composition, as a pigment-free top coat or a clear coat, in the finishing and refinishing of articles, for example motorcycles, cars, trains, buses, trucks, and aeroplanes. The coating composition after curing forms a coating having an initial gloss of at least 81 GU and a loss of gloss (LoG) of less than 0.25, the loss of gloss being determined by the formula (I) LoG =(1?e(A/X)/(1+eK)+(1?eD*?Tg)??(I) wherein K=B*(Tgonset?C) In formula I A=?8.03, B=?0.21, C=328 and D=?0.00304.

  • Patent number: 6642305
    Abstract: A thixotropic amino formaldehyde resin with a urea-functional compound, obtainable by adding a polyisocyanate-functional compound to a monoamine-functional compound or a monoisocyanate-functional compound to a polyamine-functional compound in the presence of the amino formaldehyde resin and reacting the amine and isocyanate-functional compounds to form the urea-functional compound entangled to the resin. The thixotropic amino formaldehyde resin can be used in the formulation of coating or adhesive compositions.
