Lab-metalLab-metal and Hi-Temp are both one-part, ready-to-use repair and patching compounds. Lab-metal will withstand temperatures as high as 350ºF (or onetime exposures to 425ºF for no longer than 20 minutes).

Hi-Temp Lab-metal will withstand temperatures up to 1000ºF. Lab-metal will air dry in a few hours (depending upon thickness of application and air temperature).

Hi-Temp Lab-metal needs to air dry for a minimum 24 hours, and then needs to be heat cured (as instructed on the label and in the downloadable brochure). 

Lab-metal and Hi-Temp Lab-metal must be fully hardened in order to prevent porosity or outgassing.
