Dow B-72 Acrylic Resin

Dow B-72 Acrylic Resin is a thermoplastic copolymer from Dow’s B-Series, featuring ethyl acrylate and methyl methacrylate. Renowned for exceptional clarity, UV resistance, flexibility, and archival stability, it serves widely in conservation, coatings, and adhesives. Its low Tg (~40°C), water-white appearance, and excellent film-forming ability make it ideal for sensitive applications requiring long-term durability and non-yellowing performance.

Features Of Dow B-72 Acrylic Resin

  1. Excellent UV resistance and long-term color stability for outdoor and archival applications.

  2. High molecular weight ethyl acrylate/methyl methacrylate copolymer offering superior toughness and flexibility.

  3. Low yellowing tendency and excellent clarity in film form, ideal for conservation-grade coatings.

  4. Good solubility in common organic solvents including toluene, xylene, acetone, and ethyl acetate.

  5. Reversible solubility enables re-treatment and safe removal with appropriate solvents—critical for art conservation.

Typical Applications Of Dow B-72 Acrylic Resin

  1. Museum-quality painting and sculpture conservation consolidants and varnishes.

  2. Archival adhesives and gap-fillers for historical paper, parchment, and textile restoration.

  3. Protective coatings for archaeological artifacts and ethnographic objects.

  4. Base resin for custom-formulated conservation media and reversible overpaint systems.

  5. Temporary protective films for stone, plaster, and mural surfaces during cleaning or transport.
