Project Examples:

Corrosion Testing  
Valve Stem (control)

“Can does not empty” complaints were traced to propellant leakage through the valve cup seal or the valve stem gasket seal. The root cause was attributed to using a stem gasket with an improper durometer (hardness) specification.

“Poor Spray Pattern” complaints were traced to precipitation of partially soluble solids in the formula which accumulated and resulted in partial clogging of the aerosol valve system.

“Weak Spray” complaints were traced to a loss of container pressure over time. The root cause was attributed to a defective lot of lathe cut gaskets which resulted in propellant loss through a compromised can crimp seal.
