Epoxy Coating Thickness On Steel

Many proprietary coatings are currently available for coating galvanized steel.

Epoxy coating thickness on steel. Although designed primarily for the protection of ferrous metals the coating may be applied directly to non metallics such as wood tile glass masonry porcelain plaster fiberglass masonite and. A class b minimum coating thickness is required for wire and welded wire reinforcement intended for use in mechanically stabilized earth applications. A nondestructive coating thickness gage can be used in the field or in the laboratory. This is a strange combination because epoxies are very impervious and latex coatings relatively pervious breathing coatings.

Previous five and six coat systems have been replaced by typically three coat alternatives and the latest formulations have focussed on application in even fewer numbers of coats but with increasing individual film thickness. Certified polystyrene blocks are for use with gages that measure over 1500 µm 60 mils with an accuracy of 2 5 µm 0 05 of thickness 0 1 mil 0 05 of thickness. Examples of this are epoxy and polyester glass flake coatings that are designed for high build thickness in one or two. These gages are available in ferrous and non ferrous models and can obtain coating thickness measurements from various metals.

Ultrasonic gages are useful for coatings on concrete or masonry surfaces. A type 1 coating is a fusion bonded epoxy coating that has been formulated to be sufficiently flexible to allow bending of the coated wire or welded wire reinforcement. A type 2 coating is a. Nondestructive coating thickness gage.

Epoxy and latex coatings are particularly popular.
