Plastic comes in two basic types, thermoset and thermoplastic.
Thermoplastic is the one that always melts at the same temperature; while
thermoset will harden or 'set' when heated, and then not melt again until it
decomposes.
Powder coat is a thermoset process ... once the powder has cured it will no
longer melt at that temperature. At least some powders probably will start
to flow at 100F ... you have to be sure to store them at lower temperatures
until they're applied. Once applied and cured tho, they will no longer flow
at all, just discolor and eventually burn if they get hot enough.
