  • Patent number: 5880167
    Abstract: The invention relates to polyurethane compositions with a low content of monomeric diisocyanates. Trifunctional isocyanates optionally reduced in their functionality to 3.0.+-.0.7 with a monofunctional terminator are preferably used for this purpose. In this way, the compositions contain considerably smaller quantities of readily volatile isocyanates. The compositions are suitable for use as reactive hotmelt adhesives, lamination adhesives, adhesive/sealing compounds, primers and for the production of foam plastics from non-reusable pressurized containers (aerosol cans). The low content of volatile monomeric diisocyanates enables the need for safety measures in the workplace to be significantly reduced, in addition to which the disposal of residues remaining in the containers is made considerably easier.

  • Patent number: 5854332
    Abstract: Aqueous dispersions of urethane polymers and vinyl polymers (e.g., acrylics) that provide water-based coating compositions with good adhesion following humidity exposure are further improved by providing branching chain extension of the polyurethane. The branched polymers provide improved metallic pigment orientation in coating compositions. Branching is provided by the use of chain extending agents selected from polyamines having at least three primary amine groups and polyols having at least three hydroxyl groups. The vinyl monomers are polymerized in the presence of the aqueously dispersed polyurethane.
