FTH Fast Dry Conformal Coating Thinner 5L is a high purity solvent blend designed for use with Electrolube’s fast drying conformal coatings such as AFA and PUCAF. The primary use of FTH is to dilute the coating for use in dip and spray coating applications to maintain the correct viscosity. FTH can also be used as a cleaner on metal equipment found in the conformal coating process including spray guns and dip coating machinery.
