I am working on a coating system based on Epoxy binder.
I am looking for a curing agent that will work in temperature as low as -20°C, without hampering the properties. There are certain coatings sector like Food cold storage houses, where the temperature goes as low as -20°C.
You can work with low Tg epoxy system after curing, for example EPON828 cured with Jeffamine D-2000 has Tg can be low as -46C.

Do you want to cure at -20 deg C (which is a hard task) or you need a coating that remains flexible at this temperature? Then you should rather choose PUR-like or other coatings.
Hello Sir.
I am looking for a coating which will sustain all its properties like flexibility, etc. at -20°C.
You can work with low Tg epoxy system after curing, for example EPON828 cured with Jeffamine D-2000 has Tg can be low as -46C.
