Definitions

  • the present invention relates to a thermosetting powder paint binder composition comprising a polymer.
  • the present invention further relates to a cross-linker and a powder coating with adjustable gloss levels based on said powder paint binder composition.
  • the semi- and low gloss powder paints are an important segment of the powder coating market. Low gloss coatings reduce the light reflection from the coated surface and visibility of surface defects like pinholes. For the indoor segment semi- and low gloss coatings play a major role in the design and styling trends of household appliances and metal furniture. For the outdoor segment coatings with reduced gloss are desirable for use with building materials, architectural window framing, motor vehicles and other traffic applications.
  • Reduction in gloss occurs when surface irregularities or imperfections, which are equal or larger in size compared to the incident wavelength decrease specular reflection and increase diffuse scattering.
  • the intensity of reflection depends on the degree of surface-smoothness.
  • Mirrors for example, are recognised as high gloss surfaces as they reflect light with high clarity.
  • micro-rough, irregular or micro textured paint films scatter light, only a reduced amount of light is reflected. In general, the rougher the surface the lower degree of gloss.
  • a reduced gloss powder-coated surface will result when incompatible or uniformly distributed matting additives have been introduced in the powder paint formulation.
  • mineral matting additives such as silica and talc
  • incompatible organic additives such as waxes and cellulose derivatives can lead to insufficient UV and yellowing resistance, loss of adhesion, and poor mar or scratch resistance.
  • An alternative option for producing a reduced gloss coating is to use the dry blend technique. That is, mixing two powder coating paints with different reactivity's to each other.
  • the disadvantages of dry blends include poor batch-to-batch reproducibility of gloss and appearance plus higher manufacturing costs.
  • a further disadvantage is that the over-sprayed powder can only be re-used in combination with controlled, continuous dosing of virgin powder.
  • the "one-shot matt” technique is able to achieve reproducible semi- or low gloss powder paint compositions.
  • the components of the binder formulation are usually subjected to a single extrudate.
  • the binders in a one-shot matt paint composition usually contain amorphous polyester and at least one other component that is at least partly incompatible with the amorphous polyester polymer.
  • amorphous polyester usually contain (semi)-crystalline polyester, acrylic or methacrylic polymers, cross-linker or mixture of cross-linkers may be used.
  • (semi)-crystalline resins can be expensive increasing the cost of the coating. Furthermore, (semi)-crystalline resins can have a low Tg and low melting viscosity and cause a sharp drop in gloss at phase separation point during the cure. The low melting viscosity of the (semi)crystalline component complicates the extrusion of the powder paint binder. A further disadvantage is that the relatively low Tg lowers the Tg of the paint composition and compromises the powder stability of the paint.
  • Coating formulations with acrylic and methacrylic polymers can give acceptable low gloss coatings.
  • One major disadvantage of these systems is that the incompatibility between the acrylics and the polyesters is so severe that the slightest contamination leads to cratering.
  • the gloss levels of these systems are not really adjustable.
  • Low gloss powder coatings can also have inadequate mechanical properties. This is especially the case when the gloss level is les than 40% at 60°. Even more so when the gloss level is less than 30% at 60°. It is the object of the present invention to provide a thermosetting paint binder composition which has reproducible, adjustable gloss levels and/or superior mechanical properties.
  • the compositions of the present invention are particularly attractive because of their flexibility to allow the user to adjust the gloss level to suit the application.
  • the present compositions are particularly useful for low or semi-gloss applications.
  • thermosetting powder paint binder compositions comprising thermosetting polyamide, a second polymer that is at least partly incompatible with the polyamide, and crosslinker(s).
  • thermosetting powder paint compositions comprising carboxyl or hydroxyl functional polymer, thermosetting polyamide, and crosslinker(s).
