Paraloid B-72 is a versatile acrylic copolymer widely used in paleontology for the preservation and conservation of fossils. Its popularity stems from its excellent stability, reversibility, and adaptability to different environmental conditions. Paleontologists use Paraloid B-72 primarily as a consolidant and adhesive to stabilize fragile fossils, preventing them from crumbling during excavation, handling, or storage. The polymer is typically dissolved in solvents like acetone or ethanol, allowing it to penetrate the fossil matrix deeply and provide structural support without significantly altering the specimen's appearance. Additionally, its reversible nature ensures that future conservators can remove it if necessary without damaging the fossil, making Paraloid B-72 a preferred choice for fossil conservation and long-term preservation. Use on fossilized materials whereby penetration into a matrix is possible; such as bone.
