    配方类型: ADHESIVES
    配方说明: Sprayable-Fast Drying Adhesives
    配方组成: An interesting possibility, from the method of application
    standpoint, is the solvent type adhesive that is of a suitable spraying
    viscosity. When correctly applied, a smooth uniform adhesive film is
    obtained from which the solvents will evaporate quite evenly and
    rapidly. Adhesives of this type are widely used in those applications
    where a high rate of production and efficiency is required.
    The following formulations illustrate adhesives with improved initial
    tack and tack retention properties of the adhesive film. These adhesives
    are strongly recommended for use in those applications where the bonding
    of glass, leather, metal, plastics, rubber, and wood is involved
    Methyl Ethyl Ketone/130
    "Durez" 12603/-
    Zinc Oxide/5
    "Neoprene" AC/100
    "Arofene" 700/45
    "Neville" LX-685, 125/45
    "Nevastain" A/1
    Magnesium Oxide/4
    R-13 "Neville" Resin/-
    配制方法: The "neoprene" AC is broken down on a cool, tight mill for 10 minutes. The magnesium oxide, "Nevastain" A, and zinc oxide are then added. The batch is removed from the mill, cut into small sections and dissolved in the methyl ethyl ketone-mineral spirits mixture along with the modifying resins. Generally a ratio of 2:1 mineral spirits-methyl ethyl ketone blend is needed to bring the finished adhesive solution into a suitable spraying viscosity range.
    Other previously shown formulations can be made suitable for spray-type applications with adjustments in solids content and solvent balance.
