Advantages of Chip Resistance Testing for Coatings

Even when top quality ingredients are used to create coatings, such as paints, finishes, and protective coatings, there is still a risk of receiving customer complaints from product failure. One such complaint is a product failure from chipping which inhibits the product from performing the intended function.

Instruments such as a Gravelometer can evaluate the resistance of vehicle surface coatings (paint, clear coats, metallic plating, etc.) to chipping caused by the impacts of gravel and other flying objects in accordance with SAE and ASTM standards.

Below are some of the advantages of performing chip resistance testing for coatings pre and post-market:

Chip Size Testing

Chip Size Testing can determine the overall size of chips to help develop an understanding of the impact of chipping in frequently failing coating formulations. Since this type of testing uses a scale based on the total count of chips at a certain size, the determination of the chip size also contributes to a thorough understanding of how to search for a solution to the issue.

Point-of-Failure Analysis

Chip resistance testing bombards the coating with gravel, then provides a visual and data-driven result that allows experts to pinpoint at what stage the coatings fail. Finding the exact layer at which the product fails helps clarify the possible solutions to preventing a product failure.

By combining information derived from the size of the chips, the number of chips, and the layer at which the chipping occurred (including the layers through which the chipping caused overall failure), analysts can determine what ingredients or manufacturing methods lead to a low chip resistance.

Real-World Results & Applications

The method behind chip resistance testing was developed to simulate actual conditions which coatings must endure over time or in the event of a natural disaster (or similar catastrophic event). To maximize the potential strength of a coating requires testing under such simulated conditions to create realistic and accurate formula solutions.

Among tests to determine the quality of a coating, chip resistance is one of the most true-to-life. Humidity, wind, and erosion are ordinary elements of coating wear-and-tear, and are nearly universal. Chip resistance reveals more than just when a coating begins to chip; it can also determine to what elements a coating is particularly vulnerable.

When Should I Consider Chip Resistance Testing?

Whether you have determined that your coating formula fails at a certain point, chip resistance can provide an edge on your competition, limit customer complaints, and prevent them from becoming a major issue. Before-market testing is highly recommended to ensure that, in post-market, there are no lingering issues that may cause costly problems later on. Contact us to start your customized quote.
