Anticorrosive coating is an indispensable part of paint coating, that is to say it belongs to a type of paint coating, we can divide it into conventional coatings, industrial anticorrosive coatings and special coatings.

Further information about the anticorrosive coating thickness measurement and coating thickness gauge, please read this paper.

1. What is anticorrosive coating?

Conventional anticorrosive coating can be considered as a coating product that can prevent or slow down the corrosion of metals and other materials under normal circumstances. Its role is to protect the service life of metal.It is a term for heavy-duty anticorrosive coatings. It is aimed at conventional coatings. It can be applied in relatively harsh environments. 

In addition, we also have a kind of classification of coating products: special coatings, such as high temperature resistant anticorrosive coatings, antistatic coatings, that is, like high temperature resistant anticorrosive coating products. It can withstand high temperature. Generally, high-temperature resistant anticorrosive coatings can withstand high temperatures of several hundred degrees, while professional coatings with special treatments can withstand high temperatures to work. There are also antistatic coatings. In addition to the general chemical corrosion protection of the coating object, this coating product can also discharge the static electricity accumulated in the product in a short time, thereby protecting the coating object from being damaged by static electricity.

2. Anticorrosive coating thickness

The coating thickness is an important indicator of whether the anticorrosive coating works. Coating thickness measured by an anti-corrosion coating thickness gauge is one of the most important quality inspection indicators of an anti-corrosion coating. For anti-corrosion coatings, anti-corrosion coating thickness gauges are almost essential instrument for coating thickness measurement. The coating has been applied in various industries and it is easy to detect. It has developed into many types such as magnetic induction, ultrasonic, eddy current and simple measurement. Ferromagnetic metals are very different from non-ferromagnetic metals. Therefore, special magnetic thickness gauges are used when measuring the anticorrosive coating thickness on ferromagnetic metal substrates, but some anticorrosive paint thickness gauges are currently available for simultaneous measurement of ferrous and non-ferrous metal substrates, such as anti-corrosion thickness gauge LS223. LS223 coating thickness gauge can measure the coating thickness on ferrous and non-ferrous metal substrates.

3. How to measure anticorrosive coating thickness ?

Anticorrosive coating thickness can be painted on ferrous or non-ferrous metal substrates. For different substrates, we shall use corresponding coating thickness gauges for different substrates.  Linshang dual use coating thickness gauge LS223 can test the coating thickness on both ferrous and non-ferrous substrates. For the detailed anticorrosive coating thickness measurement methods, we can refer to the following steps:

  • Step1: Press the coating thickness gauge probe on the zero adjustment plate or uncoated workpiece to perform zero adjustment

  • Step2: After completing the zero adjustment, place the coating thickness gauge on the anticorrosive coating 

  • Step3: The measured coating thickness will be displayed on the screen in 0.5s

  • Step4: If you need to measure the coating thickness on different substrate, the coating thickness gauge will identify the substrate and switch to another mode.
