  • Patent number: 11548964
    Abstract: One-part, curable compositions that have a soft feel when applied as a coating/film and cured, may include a) at least one isocyanurate tri(meth)acrylate or derivative thereof; and at least one of components b)-e), wherein: b) is at least one urethane diacrylate; c) is at least one monofunctional or difunctional reactive diluent; d) is at least one solvent; and e) is additives. The one-part, curable compositions are advantageous with respect to softness and tailorability of softness as well as other properties such as mar resistance, abrasion resistance, stain resistance and chemical resistance. Due to their advantageous properties, embodiments of the one-part, curable compositions described herein are viable for a wide range of coating applications including automotives, aeronautics, cosmetics, small appliances, packaging and consumer electronics. Methods of making and using the one-part, curable are also described herein.

  • Patent number: 7344781
    Abstract: This polymeric composition comprises a blend of polymers comprising: (a) a semi-crystalline fluorinated polymer, (b) an acrylic polymer, and is characterized in that it additionally comprises: (c) from 0.01 to 20% by weight, with respect to the total weight of the semi-crystalline fluorinated polymer and of the acrylic polymer, of a nucleating agent in the form of particles having a melting point greater than that of the semi-crystalline fluorinated polymer. These compositions result in formulations in the form of dry powders or of powders in suspension in water or in a latent solvent for the semi-crystalline fluorinated polymer. Applied to a substrate, these formulations give, by baking, glossy and stable coatings comprising spherulites with a size of less than 5 ?m.

  • Publication number: 20040221395
    Abstract: The invention concerns leather finish compositions containing at least an aqueous dispersion of film-forming polymer at room temperature without cosolvent, or plasticizing agent and optionally a cross-linking agent. Said dispersions free of organic solvent provide non-sticky and abrasion resistant coatings with good water resistance. Said dispersions consist of structured polymer particles having one or more soft phases (Tg<20° C.) and one or more hard phases (Tg>60° C.).

  • Patent number: 6723779
    Abstract: A latex which forms a film by evaporation at a temperature of less than 40° C. is based on hydrophobic polymer particles having a core/shell structure. The particles consist of 70 to 90% by weight of at least one polymer with a soft character having a glass transition temperature of less than 20° C. forming the core, and 10 to 30% by weight of at least one polymer with a hard character having a glass transition temperature of greater than 50° C. forming the shell. When applied to any surface and after drying at low temperature, the latex, without the use of any coalescents or volatile organic compounds, provides a continuous film which is homogeneous, has no surface tack and has good mechanical integrity.
