Subject: Dow Aegis Antimicrobial, "The Mold Solution"
South Carolina State Archives has inquired about the advisability of using a service called "The Mold Solution," which as far as I can tell offers to fix mold (in lieu of climate control), guaranteed, for 3 years using (per their MSDS) organosilane polymer -- 18% (3-chloropropyl) trimethoxysilane plus 84% octadecylaminomethytrimethoxys Ammonium Chloride. The vendor offers to "treat the HVAC system, walls, shelving, and documents or books, or any other surface where mold may exist and grow." !!!! The stuff, which is a fog or spray (undescribed) apparently seals microbial forms under a non-removable coating. Now, I know it's a bad idea logically, but does anyone on the list know why it's a bad idea chemically? Has this been around long enough to have any experience in its aging properties? Does experience with masonry sealants offer any model? Does it actually kill mold spores, other than by suffocation or encapsulation? Has it ever been used in a collection? The typical application is apparently homes and hospital materials. Thanks for anything you can offer.
