Is there any material that has the potential to resist falling snow flakes from sticking to it surface during heavy snow?
I was told that PTFE (teflon) has a special properties that nothing will stick on it. But after i test a PTFE coated baking tray during snow, found that it's not really the case. (in the internet there are many type of PTFE make (brand) and coating number (milli-meter)) does the make and coating number do play a part to it properties?
Actually i want to put a signboard (approx. 1 meter x 1.5 meter) outside my home but during snow it covered with snow flakes. Any suggestion to over come this problem?
Thank you Raj
