Epoxy Coating Thickness On Steel

These gages are available in ferrous and non ferrous models and can obtain coating thickness measurements from various metals.

Epoxy coating thickness on steel. Method of test for measuring epoxy coating thickness on steel reinforcing bars welded wire mesh and dowel bars using type 2 gages a. The most popular epoxy floors for businesses are those in the range of 10 20 mils thick and will usually comprise of a 2 to 3 coat system. Scope this test method describes the procedure for nondestructive spot thickness measurements of non magnetic green flexible astm a775 and purple gray rigid astm a934 epoxy coatings over ferrous materials. The molten powder flows into the profile and bonds with the steel.

Standard coating thickness range of stand alone fbe coatings is between 250 and 500 micrometers even though lower or higher thickness ranges might be specified depending on service conditions. 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. Nondestructive coating thickness gage. Per gallon at 3 mils dft dry film thickness.

Take a minimum of 10 gauge readings at regular intervals throughout the bare blasted bar for zero baseline on the rough surface. Per gallon at 3 mils dft dry film thickness. In practice these values can be reduced by at least 25 by loss factors. If you re putting an epoxy floor in a higher traffic area then you will need a thicker epoxy floor if you want to it to withstand that wear and tear.

Theoretical coverage epoxy primer 4210. A nondestructive coating thickness gage can be used in the field or in the laboratory. Quality assurance tests for epoxy coating thickness on dowel bars 1. Place the bare blasted bar sample of the same diameter on a non magnetic working surface.

A durable epoxy coating over 1018 steel or 6061 t6 aluminum and protective binder ensures long life. Ultrasonic gages are useful for coatings on concrete or masonry surfaces.
