Drop Test To Evaluate The Coating Adhesion Strength

Coating, paint or plating are the vital part of product completion of any industry. That is because the coating is the last finishing layer that acts as a barrier against the outer environment and the original product surface. Therefore, it's very important that the product coating is strictly tested and evaluated for its adhesion strength. There are several ways to inspect the coating properties, however, the test that delivers the real-time results by recreating damage-prone situations is the Drop Test conducted by a highly precise and standardised Drop Tester.

How the coating adhesion plays a vital role?

Coating of paint or powder material not only enhances the look and aesthetics of the product but is also vital for brand recognition and reputation. A good quality coating delivers better looks and helps the customer to relate and develop a tendency to select the same every time. Hence, the coating is no more just a corrosion-resistant material but helps manufacturers with much more than earning profit.

The paint that is coated on the packages or products must deliver a high level of retention strength which means the more they stick to the surface or latched to the external area of the product, the more it delivers protection against any kind of weathering condition including corrosion and resistance against physical damages.

The coating delivers this much protection due to its immense adhesion strength with the application surface on which it's applied. The chemical structure of a coated paint is bonded with the surface molecule. The stronger this bond, the stronger will be the retaining of the coat.

But if the coating has a weaker adhesion strength it will lose its integrity and begin to crack and wear off the product.

How one can evaluate the coating quality through a drop test?

Drop tester is specifically designed equipment that is used to evaluate the performance quality of packages when dropped from a set height at a defined angle. On getting a dropper the package will either sustain the drop or will deflect based on which the performance is judged.

In the case of coating, the painted products or packages can be dropped using the drop tester at different heights and angles to check the exact situation where the coating cracks or after how many falls it losses its adhesion strength or at which height the coating worn off the product.

This way the coating can be easily evaluated and the manufacturer can see before hand the performance of its coating when it encounter a vertical or angular fall.

The equipment has a strong base plate taht is meant for sample placement. The plate is attached to a static trunk on which the plates can move to distinct heights. The strong base plates can open up and let the sample fall. The equipments allows angular as weel as a straight drop. With a rugged structure, the machine ensures zero movement during the test procedure even if heavy containers or boxes are used.

Equipped with an adjustable angle holder to set the required drop angle for the test that can be as per set industry. It also comes with safety features that include Locking Pin that assures all the set parameters are fixed before the test method is applied. Users can easily move the testing platform to any height by using high-end technologies like Guide Mechanism. The machine also offers Drop Height adjustable clamps that allow him to test their sample in a wide range of heights for the drop. The machine is available in a high-end Pneumatic Model and delivers a range of platform sizes that can be decided as per the client.
