HMG Acryloid B-72 is a heat and waterproof adhesive in tubes
designed for repairs to pottery, wood, metal, ivory, glass, or other porous
substances, except rubber. HMG B72 is virtually colorless and boasts an
ability to resist yellowing for a considerable period of time. Its glass
transition temperature is approximately 40 C. Excess adhesive can be removed
with acetone. A slower drying time than the cellulose nitrate makes this
product the choice for archaeological material both on and off site.
