Hi im applying water based urethane coating on a rubber surface at 130 degres celcius. Curing time is 120 sec and surface of the rubber goes up to 250 degres celcius. I got bad result on solvant resistance with Naphta. Result is better when i lower temperature but the rubber is not cure enough.
Q: 250 celcius is it too high for water based uretane coating
Q: Solvant(xylene) base coating support higer temperature than water based?
