Reply To: Paraloid B-72 and marking museum artifacts


I certainly agree with Ella concerning the drying time. I have encountered a problem in the past numbering bare metal artifacts. Regardless of the drying time, the number would still smear. I consulted numerous conservators and now use B-67 as a base coat with B-72 as a top coat when numbered metal artifacts. B-67 is not as stable as B-72 and it can yellow over time, but it does allow me to successfully number this type of artifact.
