Greetings all: I have an exhibit fabricator who wants to use an adhesive product called 1-Shot Speed Dty UV Acrylic Clear (4005). The application is on graphics inside a sealed artifact case. The fabricator claims, ³It is an acrylic glue. So it is no different than plexiglass². The MSDS from the manufacturer lists the following ingredients: INGREDIENT NAME | CAS # | % Stoddard solvent 8052-41-3 | 30.01 - 40.00 Methoxypropanol acetate 108-65-6 | 20.01 - 25.00 1,2,4-Trimethylbenzene 95-63-6 | 0.10 - 1.00 Its crunch time. The exhibit is to open in the next 10 days. Should we be concerned about these chemicals not having enough time to off gas? Thank you for your time to respond. -- John W.
