We’ve Released New Hydrophilic Products!

So much of our company’s focus is on creating superhydrophobic and oleophobic coatings. That is our bread and butter, so to speak. But, in reality, we are not just repellency coating experts; we are SURFACE MODIFICATION experts – an intentionally broad term that represents the wide breadth of our research and experience with modifying many different surfaces to have non-native properties. Lately, we have had an increasing number of businesses approach us about our hydrophilic coatings. I hear from the advertising guys that more people click our ads about hydrophilic coatings than any other technology. That was surprising to me, and really served to illustrate how much the word is getting out about this kind of technology. So I figured this blog post was timely.

This week, we launched a new line of hydrophilic coating technologies. AcuWet coatings are designed to provide enhanced wetting ability to most surfaces. Differentiated in durability and applicable substrates, we have launched 4 distinct AcuWet products.

Here is a raw demonstration of the wetting ability of an AcuWet hydrophilic coating (AcuWet SGP). This is a small piece of titanium mesh. There is a slight capillary effect, which helps the wetting, but the hydrophilicity is still apparent:

So when would a hydrophilic coating be needed as opposed to a hydrophobic coating? Well if you remember, I have already answered this:

New NanoProof Products- IPX7 Waterproofing Achieved!

Wow, even I didn’t expect the success we recently found with some advances in our NanoProof line of PCB waterproofing products. As you can see, our last post regarding NanoProof argued that conformal coatings were obsolete. If they weren’t before, they most certainly are now. We recently unveiled two new NanoProof products (7.0 & 8.0) that have successfully achieved IPX7-level waterproofing on both Samsung and iPhone devices. This is monumental for the electronics industry.

Have a look at the videos below that demonstrate on each device. We have started fulfilling orders for these products, so contact us if you are interested in testing for your application.


NanoProof: Our Alternative to Conformal Coating

Waterproofing electronics and PCBs has been on the minds of electronics manufacturers for years now. By now, everyone has probably seen Samsung’s popular commercial featuring Lil Wayne pouring champagne all over his cell phone (& dunking it in the fish tank) with no ill effects.

Conformal coatings and expensive parylene vacuum deposition equipment have always been the only solutions for making electronic devices impervious to liquids. The market was missing something, though. We wanted to develop a product that required no equipment and allowed easy rework throughout the PCB manufacturing process. It needed to be incredibly easy to apply and offer a range of waterproofing levels to meet unique project requirements.

Enter Aculon’s NanoProof. Continue reading NanoProof: Our Alternative to Conformal Coating

What is the difference between a hydrophobic and superhydrophobic coating?

Well it seems like we are fighting a losing battle…..

“Superhydrophobic” has become the common nomenclature to describe ANY surface which easily repels liquids. Sometimes it is used correctly. Most times, however, it is incorrect. A superhydrophobic coating is a coating that has a water contact angle of greater than 150 degrees and a sliding angle of less than 10 degrees.

Most of the coatings that we have found to functionalize surfaces most effectively are not superhydrophobic – Continue reading What is the difference between a hydrophobic and superhydrophobic coating?

Does the Surface Have to Be Clean Before Applying a Nanocoating?

YES!!

Yes, the surface has to be absolutely clean for our coating to work effectively. That doesn’t mean visually free of dirt. It means free of any surface contaminants at all (even the ones you can’t see). If a customer comes back to us having purchased a hydrophobic or oleophobic coating from us and explains that our coating isn’t working, it usually means one thing: Continue reading Does the Surface Have to Be Clean Before Applying a Nanocoating?

Surface Preparation: What Does Clean Mean?

This is a question that has many different definitions (depending on who you ask), and therefore “levels” of cleanliness from visibly dirty all the way down to free of impurity at the atomic level. How much cleanliness is required depends heavily on the application; knowing what the right level is for surface coatings demands some intimate knowledge of the system being evaluated.
