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.
