  • Publication number: 20090305044
    Abstract: Thermoset polymer particles are used in many applications requiring lightweight particles possessing high stiffness, strength, temperature resistance, and/or resistance to aggressive environments. The present invention relates to the use of two different methods, either each by itself or in combination, to enhance the stiffness, strength, maximum possible use temperature, and environmental resistance of such particles. One method is the application of post-polymerization process steps (and especially heat treatment) to advance the curing reaction and to thus obtain a more densely crosslinked polymer network. In general, its main benefits are the enhancement of the maximum possible use temperature and the environmental resistance. The other method is the incorporation of nanofillers, resulting in a heterogeneous “nanocomposite” morphology. In general, its main benefits are increased stiffness and strength.

This emphasizes the very joining zones which it is intended that the viewer of bonded products should not perceive. The adhesive should therefore be matted after curing. The adhesive has for its basis a polymerization adhesive, preferably a (meth)acrylate-based adhesive. Two different kinds of silica are added as disperse powder to the polymerization adhesive, namely a silica powder having an average particle size of from 1 ?m to 10 ?m (matting agent) and a silica powder having an average particle size of more than 10 ?m up to 200 ?m (texturing agent).

  • Publication number: 20090208663
    Abstract: A wood substrate is coated by spray-applying onto the substrate a 100% solids transparent coating composition containing sufficient silica-containing semithixotropic particulate having an average particle size of about 1 to about 20 micrometers to provide improved coating holdout, and curing the thus-applied coating. The coating may be applied at lower wet coating weights (thinner wet coating thicknesses) than a coating that does not employ silica-containing semithixotropic particulate. On variable grain density wood substrates such as cherry, the coating exhibits less localized soak in (better holdout) and provides a cured finish with a more uniform appearance over high and low grain density regions.
