  • 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.

  • Patent number: 5228905
    Abstract: A treating composition for a porous substrate such as wood is provided in the form of an oil-in-water dispersion comprising a dispersed phase of an organic solvent in relatively low amounts to reduce V.O.C., a water repellent, and a stabilizing surfactant. Optionally, preservatives and resins may be included. Penetration with relatively low organic solvent content is achieved by producing a dispersion having a maximum mean particle size of 3000 .ANG.. Also disclosed is a method of preparing the dispersion with a microfluidizer.

  • Patent number: 4913972
    Abstract: Disclosed is a method for providing a wood substrate with durability against weathering comprising at least two steps (A) and (B). Step (A) consists of appying to the wood substrate a transparent treatment comprising an organosilicon-containing compound having at least one hydrolyzable silyl group in a carrier for said compound. Step (B) consists of thereafter coating the wood substrate with a transparent, film-forming, coating composition. The coating composition is characterized in that a transparent free film from the coating composition retains an elongation of at least 20 percent after at least 1,000 hours exposure in a Xenon Weatherometer.
