Autoclave Recommendations for Coated Glass
Suggestions for autoclaving plastisol are 121 C(250 F) @15 PSI for 20 minutes. Portions of the coating may absorb a small amount of water vapor and appear cloudy after autoclaving. The cloudiness will disappear as the coating dries. Autoclaving effects in the coating will vary slightly due to equipment, container size, configuration, procedure and frequency of procedure. It is recommended that containers do not touch and that the pressure be allowed to return to zero before removing from the autoclave, A sudden release of pressure may cause the coating to separate for the glass and produce air pockets under the coating.
Believe it or not we have to state here that the container must be clean and not have any residual product or chemical in the bottle and must not have a closure in place.
Testing of a sample is the best way of determine if the safety coating will work for your application.
