  • Patent number: 9796802
    Abstract: The present invention is directed to resins made from cashew nutshell liquid and vinyl hydrocarbons and processes for manufacturing the resins. These resins exhibit lower viscosity than the phenol-based homologs. They also exhibit good compatibility with a wide range of solvents, mineral and natural oils, epoxy curing agents, liquid epoxy resins, and polymers, which make them suitable additives as non-reactive diluents for solvent-free coating formulations; tackifiers for structural adhesive, pressure sensitive and hot-melt adhesives; stabilizers for lubricants, fuel and polymer formulations; plasticizers for thermoplastic polymers and processing aid for rubber compounding and stabilizers for respective rubber artifacts. These resins are also valuable precursors for the manufacture of epoxy resins and polyols for coating, adhesive and composite omulations exhibiting ameliorated performance in water repellency, anti-corrosion, and fast hardness development during cure.

  • 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.

  • Patent number: 5728769
    Abstract: Aqueous dispersions of urethane polymers are disclosed that provide water-based coating compositions with good adhesion following humidity exposure. The polyurethane is made from a first and a second polyisocyanate, the first polyisocyanate having at least one open carbon chain greater than six carbon atoms in length between two isocyanate groups, preferably at least eight carbon atoms in length. The dispersion is particularly useful as a binder resin in coating compositions having pigments that normally have a detrimental effect on adhesion.
