Notes for Autoclaving:

The suggested conditions for steam sterilization are 121° C (250° F) @ 15 psig for 20 minutes. Portions of the coating may absorb a small amount of water vapor and appear cloudy after autoclaving, however, the cloudiness will disappear as the coating dries. To speed Clearing, glassware can be dried in a 49 - 66° C (120-150° F) oven.

Autoclaving effects on the coating will vary slightly due to equipment, container size, and configuration, procedure, and frequency of procedure. It is recommended that containers not be autoclaved touching each other to avoid possible sticking problems. Also, it is recommended that the autoclave pressure be allowed to return to zero before removing glassware. A sudden release of pressure may cause the coating to separate from the glass and produce air pockets under the coating. Evaluation of a sample is the best way to determine if the safety coating will work for your application.
