Lab-metal or Hi-Temp Lab-metal?
Lab-metal is available in two different variants:
There are a few points to consider in determining whether Hi-Temp Lab-metal would be required over standard Lab-metal, for a given high-temperature job.
-
For powder coating processes at temperatures less than 176°C, Lab-metal may be used (even for multiple oven passes).
-
For powder coating processes in which the metal parts will never be subject to temperatures higher than 218°C, for durations no longer than 20 minutes, for no more than one oven pass, Lab-metal may be used.
-
Hi-Temp Lab-metal must be used in powder coating processes running at temperatures above 218°C.
-
Hi-Temp Lab-metal must be used if a part is to be exposed to temperatures above 176°C for more than 20 minutes in duration (or multiple high-heat exposures).
Hi-Temp Lab-metal must be applied in thin layers and allowed to air dry for at least 24 hours, then heat cured as instructed on the label. If Hi-Temp Lab-metal is not completely dry when subject to heat, and if the product is not properly heat hardened, outgassing or bubbling may occur.
