Looking for a plastic coating for use as an insulator and for creating a nice finish coating surface. Some of the requirements for this plastic are: The plastic can accept color additives; the plastic can be applied to the outside of a stainless steel or aluminum can; the plastic should have insulating properties to keep heat from escaping from the heated can; the plastic can be applied by dipping or spraying; the finished look should be smooth; the plastic product should be able to withstand a constant 325 degrees F. after the curing process. Is there any such plastic product out there for this use or should I be looking at a powered metal technique? Any help is appreciated.
