You will need the Adobe® Acrobat® ReaderTM, a plugin available from Adobe Systems, Inc. to view swatches

Clear base coat provides a barrier between specimen and accession number

Features:
  • Available in fluid or crystal form
  • Reversible, with long-term integrity


  • Description:
    Applying a clear lacquer layer on an object prevents inked numbers from bleeding into the object and allows for removal, if necessary.

    Options:
    Acryloid B-67 (isobutyl methacrylate polymer) is chemically inert and resistant to discoloring, aging, temperature changes and exposure. It may yellow slightly over time but the resin has better working properties than B-72. The crystals are soluble in xylene, toluene, mineral spirits and aromatic solvents. Test before using on painted or unpainted non-porous surfaces. Do not use on wax figures.

    Acryloid B-72 (ethyl methacrylate copolymer) is a general purpose, non-yellowing resin with excellent flexibility and the best aging properties of barrier materials. The crystals are soluble in toluene, xylene and methanol. As a barrier, it is usually used in a 25% solution. Use only on unpainted non-porous surfaces in a ventilated area. Not for use on plastics

    Notes:
    Barrier coats should only be used by a trained conservator. Always apply in a well-ventilated area and test before using.

    Acryloid B-67 and B-72 is available in fluid or crystal form. Fluid form is a hazardous material and cannot ship via air or ocean freight.
