Spray adhesives are often thought of as a convenience; open up the can shake it several times, then spray. But how exactly does that work? Spray adhesive products in and of themselves are an extremely complex assembly that requires much lab time to make sure they perform as intended every time. There are many parts to a can of aerosol that not only allow material to be inserted into the bottle, but allow the substance to be released. Shelf life of a can of spray adhesive can be a few years, and still respond at a moment's notice.
