Epoxy Coating Thickness On Steel

A nondestructive coating thickness gage can be used in the field or in the laboratory.

Epoxy coating thickness on steel.

Many proprietary coatings are currently available for coating galvanized steel. Ultrasonic gages are useful for coatings on concrete or masonry surfaces. Previous five and six coat systems have been replaced by typically three coat alternatives and the latest formulations have focussed on application in even fewer numbers of coats but with increasing individual film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.

These gages are available in ferrous and non ferrous models and can obtain coating thickness measurements from various metals. In most cases the supplier did not base his coating formulation on a scientific. Consisting of steel it epoxy coating 4907 applied over lead free steel it epoxy primer 4210 the system adheres aggressively to metal surfaces. This is a strange combination because epoxies are very impervious and latex coatings relatively pervious breathing coatings.

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 durable epoxy coating over 1018 steel or 6061 t6 aluminum and protective binder ensures long life. Nondestructive coating thickness gage. A class b minimum coating thickness is required for wire and welded wire reinforcement intended for use in mechanically stabilized earth applications.

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.
