Paraloid™ B-72 by-the-gram

Paraloid™ B-72 is a thermoplastic acrylic resin supplied as solid pellets. It is commonly used as a consolidant and adhesive for mineral specimens, fossils, ceramics, wood, and other porous materials. The resin dissolves in solvents such as acetone, ethanol, or toluene to produce solutions of various concentrations.

When applied, Paraloid B-72 forms a clear acrylic film that helps consolidate fragile materials and can be removed later with appropriate solvents. Because of its stability and reversibility, it is widely used in museum conservation and restoration.

Stabilization Instructions

  1. Clean using a soft brush and water to remove dust or dirt.

  2. Dry the specimen for 24 hours at room temperature if it is wet. (Wet specimens will not stabilize properly and may develop a white residue).

  3. Document the weight before beginning.

  4. Mix B-72 with a solvent (Acetone or 100% Ethanol) to a 10% concentration (e.g., 10g B-72 to 90g solvent) and stir until dissolved.

  5. Use a dropper or dip the specimen into the solution.

  6. Allow it to dry completely (several hours).
  7. Any remaining white or shiny residue can be removed with a quick rinse of solvent.
