Introduction:

As utes continue to be the workhorses of various industries, owners are increasingly turning to tub liners to shield the trays from the challenges of daily use. While these protective layers offer several advantages, they also come with their own set of considerations. In this article, we'll explore the pros and cons of tub liners for utes, helping you make an informed decision on whether this accessory is the right fit for your workhorse.

Pros of Ute Tub Liners:

Protection Against Wear and Tear:

Pro: Tub liners act as a robust shield, protecting the tray from scratches, dents, and general wear and tear caused by the transportation of heavy loads and equipment.

Enhanced Durability:

Pro: By adding an extra layer to the tray, tub liners significantly improve the overall durability of the ute, ensuring it can withstand the demands of heavy-duty use over an extended period.

Impact Resistance:

Pro: The added thickness provided by tub liners enhances impact resistance, reducing the likelihood of dents and dings when loading or unloading heavy items.

Corrosion Prevention:

Pro: Tub liners create a protective barrier against rust and corrosion, especially in regions with variable weather conditions. This is essential for maintaining the structural integrity of the tray.

Easy Maintenance:

Pro: Cleaning and maintaining a tub liner is typically straightforward. Most liners can be easily washed, ensuring a clean and presentable tray for both practical and aesthetic purposes.

Cons of Ute Tub Liners:

Potential Water Trapping:

Con: In certain designs, water and debris can become trapped between the tub liner and the tray, leading to potential corrosion over time. Regular maintenance is crucial to prevent this issue.

Installation Challenges:

Con: Depending on the type of tub liner chosen, installation can be a complex process. Spray-on liners, for example, often require professional application, while drop-in liners may need precise fitting for optimal results.

Compatibility Issues:

Con: Ensuring the tub liner is compatible with the make and model of your ute is crucial. Different liners are designed to fit specific vehicle dimensions, and choosing the wrong one may result in poor fitment.

Heat Retention:

Con: In some cases, tub liners may retain heat, potentially leading to issues in extremely hot climates. This can affect the cargo or tools stored in the tray.

Cost Considerations:

Con: Quality tub liners, especially spray-on solutions and custom-fitted liners, can be relatively expensive. While they offer long-term protection, the initial investment may be a deterrent for some buyers.

Conclusion:

Powder coating and Creakoting offer a high-performance coating that improves the durability, resilience and lifespan of metal products.

Concrete sealers are applied to concrete to protect it from surface damage, corrosion, and staining. They either block the pores in the concrete to reduce absorption of water and salts or form an impermeable layer which prevents such materials from passing.

Research from major concrete authorities, including the American Concrete Institute, Portland Cement Association, and the National Ready Mixed Concrete Association confirm that most concrete damage is attributable to surface moisture intrusion.The most pervasive form of concrete damage is surface scaling from freeze/thaw.Other forms of damage include alkali-silica reaction (ASR), chemical intrusion, and corrosion of steel reinforcements.

Holiday testing for protective coatings

So, when it comes to protective coatings, you might find yourself encountering what is known as a holiday test. No, it doesn’t mean a literal holiday! Though get one might be nice this time of the year.

No, it’s basically a method of identifying a series of different defects that can lead to a potentially premature failure of the coating. The test is also known as continuity test or pinhole test.

Now with that out of the way, let’s talk about what a holiday test identifies.

Well, it can identify classic defects like voids or pinholes and even cracks, or thin spots or a small containment within the coating. In general, we call these defects “discontinuities”. They are usually not visible to the naked eye.

Identifying discontinuities or holiday

Ok, so now we know what discontinuities are, but why do they matter? And why should we be concerned with holiday tests in the first place?

Well, whenever a project involves protective coatings, the specifications almost always mention conducting holiday tests. Now, this is especially true for surfaces that are going to be subjected to harsh environments. You know, liquid immersion or submersion into the ground.

Ok, so how do we conduct a holiday test?

Well, first, you have to know that this test can only be performed on non-conductive coatings that are applied to conductive surfaces.

Holiday Test Instruments

Now that you know when to conduct it, let’s look at the instruments suitable for this test. These are usually divided into two distinct categories:

The first is Low voltage “wet sponge” testing,

And the second is high voltage “spark testing”

Holiday Test by Wet Sponge Detector

Now, this test uses two 2 different voltage settings. The first is the 9V setting for thicknesses of 300µm or less and the second one is 90V for greater thicknesses up to 500µm.

Now let’s talk more about this instrument. The wet sponge detector consists of:

An Open-cell sponge

A set comprising of a connector and a shaft

Audible discontinuity indicator

A ground cable

A wet sponge device

Phew! Finally done with our little “wet sponge”.

Holiday Test by High Voltage Detector

Now that our little “wet sponge” is out of the way, let’s move on to high voltage spark testing.

This test is reserved especially for thicknesses greater than 500µm.

Beware though, if you conduct this test on thicknesses that are any smaller, you run the risk of damaging your precious coating. We don’t want that, now do we?

The detector for this test is further divided into two distinct sub-types;

Direct current

Pulse type

You can’t test if you don’t know how to setup the detector, can you? The setup consists of:

Electrodes,

a ground cable,

and an electrical device

In this case though, there is no specific voltage, so you have to look at the manufacturer’s specs for details. For example, when dealing with thicknesses of 1000µm ranging up to 1500µm, the specific voltage is around 5000V.

Applicable Standard Now remember that regardless of whichever method you use, make sure that the coating is thoroughly dried out and fully cured as per manufacturer specifications.

Oh and also, don’t forget that the standard applicable here is ASTM D5162.

And, it is recommended that the Quality Control Coating Inspector must always refer to this specification religiously to get the right information so that they can perform the test effectively.

Now you know how to conduct a holiday test.

Happy testing!

Since Parylene and its derivatives have many excellent properties, the research on them is very meaningful. Parylene reactive coatings prepared by the CVD method can be applied to various substrates, such as polymers, metals, composite materials, etc. These coatings are a general platform and do not depend on changes in the chemical composition of bulk materials.

In addition to being used as protective coatings, insulating coatings, interlayer dielectrics, electroluminescent polymers, and sensors, Parylene can also be used as biomaterials. Commercial Parylene coatings have been successfully used in stents, pacemakers, nerve Metaprobes, biological MEMS, and other devices, but these coatings are all non-functionalized and lack further modified active functional groups, so they cannot be effectively used as carriers of biomolecules.

Bioactive surface functionalization

The preparation of reactive polymer coatings is powerful biotechnology for complex surface engineering. Bioactive surface functionalization, which enables precise control of biomaterial surfaces and biomimetic design, is crucial in many biomedical applications such as drug delivery, biosensors, medical implants, and tissue engineering.

These functionalized biomolecules can be immobilized to substrate-independent active CVD polymer coatings to suit the needs of various biomedical applications. As a recognition site, the functionalized substrate surface can induce and alleviate a series of vital physiological functions in cells, such as adhesion, migration, and differentiation, and then regulate cell proliferation, survival, and other processes closely related to cell fate.

Cell-protein interactions play a central role in advanced applications in biology, medicine, and biotechnology, where the key lies in the precise control of signaling molecules on the surface of substrates, which can be used in implants, stents, cardiac In addition, it can be used as a bioanalytical tool for the detection of proteins, nucleic acids, and polysaccharides.

The CVD method is a simple and versatile method to prepare functionalized Parylene films, which can provide a range of different kinds of functional groups and adhere well to any substrate. These reactive coatings can improve the implant surface. Interface compatibility, or compatibility with complex biological properties, and stable existence under biological detection conditions. Amino or carboxyl groups can control surface charge and electroosmotic flow, and alkyl groups can provide a hydrophobic interface for electrochromatography.

All in all, functional Parylene is a unique class of aromatic polymers with unique advantages in synthesis, physical properties, and biomedical fields.
