Dow RTV conformal coatings have firm, dry surfaces for better handling and abrasion resistance after cure. Various viscosity versions facilitate different application methods. They require atmospheric moisture to cure (no ovens) and their cure rates can be accelerated by mild heat. They are supplied in solvent, with low-VOC versions available and have Mil spec, IPC-CC-830 and UL recognition. Conformal coatings are materials applied in thin layers onto printed circuits or other PCB system assembly substrates.
