    摘要： The presence of biological contaminants in a liquid coating composition is determined by measuring the carbon dioxide content of the atmosphere above the liquid and comparing the measured carbon dioxide level to a baseline carbon dioxide level. A biocide can be added to the liquid when the measured carbon dioxide level reaches a predetermined value to control the level of biological contaminants in the liquid coating composition.

    摘要： An electrodepositable composition is provided comprising: (a) active hydrogen-containing, cationic salt group-containing resin electrodepositable on a cathode; (b) at least one at least partially capped polyisocyanate curing agent; (c) at least one metal-containing catalyst; and (d) at least one material having the following general formula: ##STR1## wherein R.sub.1 is alkyl or substituted alkyl having 1 to 18 carbon atoms or aryl or substituted aryl; and R.sub.2 is hydrogen, alkyl or substituted alkyl having 1 to 18 carbon atoms or aryl or substituted aryl. The composition can demonstrate enhanced corrosion resistance at low metal catalyst levels without loss of cured film properties or appearance when electrodeposited and cured over conductive substrates.
