Abrasion And Scratch Resistance
Definition - What does Abrasion And Scratch Resistance mean?
Abrasion and Scratch Resistance describes the ability of a material to resist various types of damage such as scratches, gouges, wear and other flaws. This parameter is crucial in the coating industry since the degree of abrasion and scratch resistance in coatings will govern the longevity of the product and also determine its ability to protect the coated material against corrosion.
Trenchlesspedia explains Abrasion And Scratch Resistance
The abrasion and scratch resistance of coatings plays a vital role in protecting the anti-corrosion coating of pipelines and is one of the factors that pipeline engineers need to consider.
In addition to scratch and wear resistance, there must also be adequate adhesion between the anti-corrosion and anti-abrasion coating for maximum effectiveness. Where the anti-abrasion coating is applied on-site, proper surface preparation is required as well as proper control of parameters that control factors such as temperature and humidity during the coating process.
There are a number of test methods available to measure the characteristics of anti-abrasion coatings. There include:
- Shear Scratch Resistance Test
- Abrasion Test
- Flexibility Test
- Impact Resistance Test
- Adhesion Test
