  • Acrylate polymer abrasion and static resistant coating
    Patent number: 6004484
    Abstract: A curable coating composition for preparing an anti-static coating contains at least one addition polymerizable ethylenically unsaturated monomer, a perfluoro ionic surfactant, and a polyethoxy or fluorinated polyethoxy auxiliary compound. The perfluoro ionic surfactant and the polyethoxy or fluorinated polyethoxy auxiliary compound are present in the composition in amounts effective to impart static-dissipative properties to polymerized coatings prepared therefrom.

  • Inorganic foundry binder systems and their uses
    Patent number: 5582232
    Abstract: This invention relates to inorganic no-bake foundry binder systems and their uses. The binder systems comprise as separate components: (A) mono-aluminum phosphate in an aqueous solution containing specified phosphoric acids, and (B) magnesium oxide; and certain specified zinc compounds in either the Component A, Component B or both. The components of the binder system react when they are mixed with a foundry aggregate to prepare foundry mixes which are used to prepare foundry molds and cores. The foundry molds and cores are used to cast metals.
