For Water Heater Tank (Wet & Dry Process)
Our water heater tank enamel powders are primarily developed for wet process coating, delivering complete internal coverage, strong steel adhesion, and excellent resistance to corrosion and scaling. Wet enameling ensures durability in acidic or alkaline water. For selected designs, dry electrostatic enameling is also available, enabling faster application and uniform finishes. This combination extends product lifespan and ensures reliable hot water storage performance for residential and commercial applications.
