“What type of paint system would work best for the inside of a tank that holds a 10% chlorine solution ( 90% water). I think either a polyester or a urethane powder would be best.”
” We recommend using a thermoplastic coating like Nylon or polyethylene. These are functional materials that are normally used to coat the insides of tanks. If you must use a thermoset coating material then look closely at epoxy. It has the best chemical resistance and its low UV tolerance is of no consequence inside a tank.”
