How to test adhesion strength of a UV topcoat on plastic substrates

Testing Uv Topcoat On Plastic Adhesion is so important. This makes sure the products last a long time and look good. At Xinqinfeng we understand that stronger and more reliable plastic products means better adhesion. When we evaluate adhesion strength, our goal is to determine whether after use, contact or even an attempt at cleaning the product, the topcoat will remain in place. This article will discuss the best ways to test adhesion strength and what may affect how well that topcoat sticks to the plastic

The tape test is one of the best ways to test adhesion of UV topcoat on plastics

Here’s an easy way to tell if it will peel off. You grab a strong piece of tape, mash it down against the coated plastic Next you whip the tape off. If the top coat lifts off with the tape, it indicates poor adhesion. If the top coat remains on the plastic, that’s a positive. Another approach is the scratch test. In this test, you drag a sharp object across the coated surface. If you can scratch the topcoat off easily, that paint is not adhering well. There is also a scrape test which you perform by cutting crisscross scratches onto the top coat with a knife. Then you apply tape and see if the topcoat comes off with the cuts. The longer it sticks, the better. Finally, we had access to professional machines for more precise measuring of the adhesion strength. They press down, they measure the force it takes to pull that topcoat away from the plastic. All these different ways of working allow us at Xinqinfeng find out which UV topcoats are the best match for our products

There are many reasons that UV paint on plastic is not sticky. A major factor is the nature of plastic employed Here’s Why: Some plastics – polypropylene, for example — are more challenging to adhere to because their surfaces are low in energy ( i e, slippery) and very smooth. Some other plastics, such as PVC, have better adhesion because they can “grab” the coating more effectively. “Surface prep is also super important. Dirty, oily dusty plastic won’t hold topcoat well. Cleaning the surface correctly is half or more of the battle. The adhesion is further influenced by the temperature and humidity at application time. If it is too cold or too humidi, the topcoat may not cure properly and you could end up with poor adhesion. And the UV topcoat quality is important as well. A cheaper coating may not adhere as well as a better one. “At Xinqinfeng we are looking always out to select the best material also by proper conditions to apply the coatings. This type of thing helps us build long-lasting products that you can count on

How to Choose Adhesion Testing for UV Topcoats

So when trying to figure out how well a UV topcoat adheres to plastic? POINTS TO CONSIDER Here's what I wanted to check. The first thing you want to look at is the type of plastic that you’re using. For instance, some plastics are ultra-smooth, while others may feel rough to the touch. This might affect how well the topcoat adheres. This is a good idea if you are using a plastic that is commonly used in your projects. Next, focus on the UV topcoat. Top coatings are not all created equal. Some are formulated for certain types of plastic. Just insure that the UV topcoat you select is intended for this particular plastic

Also significant is how you apply the UV topcoat. Follow the directions closely. Applying it too thick or definitely too thin can make a difference in how well it adheres. You also want to ensure that you cure your topcoat properly after applying it. UV topcoats require UV light to cure. The attachment may not be stout “if the cure time is not correct

Final thing to consider is the plastic environment. If it will be outside, that may mean sun, rain or harsh temperatures. These can affect how well the topcoat adheres as time goes by. It can help give you an indication of how the topcoat will fare under similar conditions to which it’s being tested in. If you keep the above points in mind you can make sure that you are doing the proper tests to determine how strong this adhesion is and which directly impacts your projects quality

How to understand Adhesion test of UV Topcoats on Plastic Parts

Adhesion tests can be subjective to interpret, but there are some simple steps you can take. Look first at how much of the X topcoat came off when you tested it. If much of the topcoat flaked off the plastic, that is an indication of poor adhesion. That’s no good, especially if you want that topcoat to have some staying power. If it came off very little or none of it, then the adhesion is strong. This is a successful test and it shows that the topcoat can resist well in this type of plastic

Another factor to keep in mind is the test you used. There are various ways to evaluate adhesion. Perhaps some tests might be better suited to one situation compared with another. For instance, a very straightforward tape testing can reveal how well the topcoat adheres, but it may not be the whole story. If anything, it’s important to know what each test measures so you’re interpreting the results correctly

Lastly, what is the topcoat track record? Look at how it does in the real world, not just in the laboratory. If the topcoat adheres during testing, but fails once out in the sun or rain, it may not be a good fit for your project

Where To Score High-End Uv Topcoats Known For Their Outstanding Bonding Strength

You’re in luck because a good option you have is to find a reputable brand such as Xinqinfeng. They have a couple of UV topcoats formulated for different plastics.
