Silicone sealants, introduced in the 1960s, are still the primary type that is used in museums for building display cases. These sealants often contain Fumed silica, calcium carbonate, ground Quartz, Carbon black, talc, and plasticizers. There are two type of neutral cure RTV silicones. The first type is an alkoxy neutral-cure that releases methanol upon cure. The alkoxy neutral cure silicones are considered suitable for use on all types of metal without risk of corrosion. The second type is an oxime neutral-cure silicones that releases methyl ethyl ketoxime. These withstand temperature better than alkoxy-cure but can cause stress-cracking in some plastic boards, such as polycarbonate and acrylics.
Other types of caulking materials that have been used include polyurethanes and latex. Polyurethane elastomers provide good abrasion resistance. Latex caulking, available in the late 1960s, eliminated the use of organic solvents. They typically contain a polymer emulsion (such as Polyvinyl acetate) in water with calcium carbonate, plasticizers, and other additives.
