Ceramic Coating Hardness Test

Another common test of hardness for coatings is the infamous pencil hardness test or the wolff wilborn test.

Ceramic coating hardness test.

Dense ceramics are often measured for hardness by the knoop hardness test a method of microindentation optimized for brittle materials or thin coatings such as ceramic. Its basis is the pencil scale of hardness used by most graphic designers professional artists and many others to pick a pencil lead strength. A pencil is selected and a line about 1 2 inch long is made. The knoop hardness test is most practical for the purpose of ceramic coating tests as only a small indentation is required to evaluate and measure a material s hardness.

A ceramic coating such as opti coat pro c quartz and ceramic pro is a liquid polymer that is applied by hand to the exterior of a vehicle the coating chemically bonds with the vehicle s factory paint. The coating would have to be reasonably thick over 150 microns and it should be relatively slippery surface slip is an easy way to fool the pencil hardness test as it doesn t give the pencil the opportunity to bite. The ambient temperature during the test can also be a factor in the drying times and can have an effect on the coating s hardness. Adam s says this kit will provide 9h hardness with over 5 years of protection even in the harshest conditions.

Ceramic pro 9h has unbeatable hardness to protect your paint work. It would be highly unlikely someone would come out to intentionally vandalise a car with a real diamond ring real ruby bracelet or tungsten carbide drill. Si02 coating will cover the bulk of your protective needs. 9h is a test for the hardness level of the ceramic coating once the surface is cured.

9h refers to the level of hardness test of the ceramic coating once it cures on the surface. Subscribe to our youtube channel for more walkaraounds and educational videos. If you re unsure about the benefits of ceramic coating but want to test it. The slickness and structural integrity of a coating is the essential and predominant issue that influences the actual every day expertise with a coating.

9 layers for experimental test purposes only. To shock you no pencil today contains lead. It s based on the pencil scale of hardness which is used by professional artists graphic designers and more to pick a pencil lead strength that helps them with writing or drawing projects. Usually the coating thickness being tested is 25 4 38 1 micron and has been allowed to dry for 7 days.

Virtually each ceramic coating can attain 9h within the pencil hardness scale.
