Winkhaus’s Topcoat is an advanced protective coating applied to fittings for windows and doors. This treatment extends product durability by enhancing resistance to corrosion and extreme weather conditions. Topcoat is particularly effective for environments with high humidity or saline atmospheres, such as coastal areas, where metal components are at risk of rapid corrosion.
