Consumer Electronics

Advanced nanoGUARD (ANG) creates a durable barrier that conducts electricity, does not trap heat, has no keep-out areas, and is highly reworkable.

Thanks to its nano-scale application (“nano” being defined as one-billionth of a meter), one of the qualities that most sets ANG apart from other water-repellent electronics coatings is its ability to create a barrier that slows corrosion and repels water, oil, and dirt but permits oxygen to pass through. Its nano-scale application also means that electricity will conduct normally across coated surfaces, heat will not be trapped, and that there is no part of a PCBA that can’t be coated.

This highly unusual set of traits makes ANG an excellent choice for protecting all kinds of consumer electronics—everything from smartphones and computers to electric shavers and LED lightbulbs—anything with a PCBA in it, and today, that means just about all electronic devices. For manufacturers of consumer electronics, ACTnano has developed the ANG 100 series of nanocoating formulations. Between ANG 101, the most basic formulation currently available from ACTnano, to ANG 107B and ANG G4, the current ACTnano gold standards for the protection of consumer electronics, there is certain to be an ACTnano solution that is right for every consumer electronics manufacturing situation.

To protect devices like feature phones from accidental exposure to water, ACTnano offers ANG 103. This workhorse ANG formulation is durable and highly water and oil resistant. For more robust protection suited to world-leading phones and phablets, there are the ANG 107B and ANG G4 formulations. Electronic devices treated with ANG 107B will be capable of surviving more than one hour of complete submersion in water, while ANG G4 is capable of providing IPx7-rated protection.


Advanced nanoGUARD (ANG) has all the qualities necessary to complete the job required of a water-resistant automotive electronics coating that will operate in harsh, under-the-hood environments.

One of the greatest challenges facing manufacturers of water-resistant automotive electronics coatings is durability. Cars, trucks, and other types of vehicles are made to be outdoors, in the elements, meaning that their exposure to water, oil, and dirt is intentional rather than accidental; habitual instead of incidental. Because of this, it is not enough to protect a vehicle’s important electronic components the way one might approach water protection for a smartphone or a sweater. With this in mind, ACTnano has developed ANG 101 and 106 for use in the demanding arena of automotive electronics protection.

Vehicles coming off the assembly line today will require water protection solutions that will last a minimum of ten years. These coatings must be capable of coping with extremely harsh under-hood environments, especially when applied to vehicles using internal combustion engines, which produce fumes and vapors that can attack water-resistant coatings, causing them to break down over time. Also of concern, regardless of the vehicle type, are man-made substances, like carwash detergents, that inevitably find their way under the hood and contribute to the breakdown of water-resistant coatings used to protect a vehicle’s electronics.

Advanced nanoGUARD 101 has all the qualities necessary to complete the job required of an under-the-hood water-resistant automotive electronics coating. The properties of ANG 101 are such that this nanocoating will not react chemically with any petrochemicals, and it solves only in its own solvent, which can be used to remove the coating if reworking becomes necessary at the time of manufacture. Like other ANG formulas, ANG 101 is water repellent and conducts electricity. This particular ANG coating also possesses excellent heat properties. It has an operational temperature range of -40 C to 200 C, and like all ACTnano nanocoatings, it breathes, allowing whatever surface it is applied to lose heat at the same rate as the same uncoated surface. The ANG 101 chemistry also possesses high thermal cycling capabilities, meaning it will survive more than fifteen years of exposure to the thermal cycles ordinarily experienced in an automotive application.

Advanced nanoGUARD 106, ACTnano’s premier anticorrosion coating, is rather different than ANG 101. The ANG 106 formula is the only ACTnano coating that is not a true nanocoating. Instead, it forms a thicker, permanent barrier around electronics that is conductive on force, is neither thermal neutral nor breathable, and hardens in twenty-four hours, creating a solid, insulating barrier over whatever it is applied to.


Human sweat’s corrosive properties pose a significant problem for wearable electronics—but not for products treated with ACTnano’s ANG 100 series of nanocoatings, the clear choice for the protection of wearable electronic devices.

Consumers are becoming increasingly interested in the burgeoning wearable electronics market, which includes smartwatches, GPS athletic watches for sports like triathlon and running, and recreational headphones of all types. The presence of industry-leading GPS and computer-based electronics manufacturers in this market sector, however, means that competitive advantage is going to be key to survival; ACTnano’s ANG nanocoatings can provide this edge.

Wearables present manufactures with special difficulties where water, oil, and dirt resistance are concerned. On average, humans are capable of producing as much as two liters of sweat for every hour of heavy activity. Like most other consumer electronics, the components that make wearables work are generally enclosed in metal or plastic, but unlike most other consumer electronics, wearables, like smartwatches, GPS athletic watches, and headphones, are typically placed in direct contact with the skin, and this means in direct contact with sweat, body oils, and dirt.

It’s one thing to make an electronic component water resistant; it’s another thing entirely to give that component water resistance and durability when the component is in constant contact with the body and the corrosive effects of human sweat. Human sweat can have a pH as low as 4.5 and contains a number of solutes, but perhaps of greatest concern for the electronics inside a wearable electronic device is sodium. This mineral’s corrosive properties pose the most significant problem for wearable electronics—but not for products treated with ACTnano’s ANG 100 series of nanocoatings, the clear choice for the protection of wearable electronic devices.

The six formulations in the ANG 100 series of nanocoatings provide varying levels of water-resistance and anticorrosive capabilities. Ultimately, the choice of which ANG molecule is best for a particular product should be determined by the conditions under which the product will be used, but ACTnano’s most complex chemistries to date are ANG 107 and 107B. The ANG 107 molecule was the first ACTnano coating specifically developed to counter the damaging effects sweat has on electronics and is highly resistant to complete submersion in water. (A device treated with ANG 107 will survive up to thirty minutes of total submersion.) Providing an even higher level of sweat protection and submersion survivability is ANG 107B, the most sweat-resistant formula ACTnano currently fields. In tests, ANG 107B has permitted PCBAs to survive total submersion in synthetic sweat for up to three days.


Advanced nanoGUARD (ANG) cannot be seen, felt, or smelled, and its unique molecular structure imparts an unparalleled combination of protection and breathability to textiles, making them more functional and comfortable and extending their useful life.

Advanced nanoGUARD is not just for protecting sensitive electronic components from the harmful effects of water, oil, and dirt. The exceptional resistance to water, oil, and dirt that ANG has also brings value to textile-based products. This means that stains on products like clothing, carpet, fabric furniture, and fabric shoe uppers are a thing of the past. Once a textile is treated with ANG, not even the most powerful staining agents—red wine, beet juice, mud, oil, or even blood—can penetrate the barrier ANG creates between a textile and the messy world around it.

There have been anti-stain, water-repellency coatings and/or physical membrane barriers available for use on and in conjunction with textiles for decades. Many of these have been after-market spray-on coatings for things like carpet, furniture, and shoes. The problems with these coatings, after-market or not, however, have traditionally been threefold: 1) the treatments seldom work effectively; 2) when they do work, as in the case of certain physical barriers applied to clothing, such as rain gear, these coatings and barriers tend to make the treated fabric either partially or completely impermeable, leaving the consumer wearing an uncomfortable moisture trap; and 3) almost without exception, these treatments are highly intrusive. That is, they can generally be seen and felt (and sometimes even smelled). Thanks to ANG, however, these aren’t problems anymore.

Because ANG is applied on a nano-scale (“nano” being defined as one-millionth of a meter), its unique mesh structure permits oxygen to pass freely through the barrier it creates while repelling water, oil, and dirt. Advanced nanoGUARD cannot be seen, felt, or smelled, and its unique molecular structure imparts an unparalleled combination of protection and breathability to textiles, rendering them more functional and comfortable and extending their useful life well beyond that of uncoated textiles.

Advanced nanoGUARD textile-protection formulas can currently be found on Chicago shoe manufacturer BucketFeet’s products as well as on the high-fashion men’s and women’s designs produced by Chicago-based clothing designer Borris Powell.


Products treated with Advanced nanoGUARD literally outshine untreated products.

Advanced nanoGUARD glass and ceramics nanocoatings are a must-have for manufacturers whose products make extensive use of glass and/or ceramics. Solar panels lose 30 percent of their energy efficiency simply because their surfaces become dirty. Advanced nanoGUARD was specifically engineered to prevent the buildup of light-obstructing agents such as common dirt and moss.

Many ceramic products, like urinals and bathroom fixtures, tend to become havens for mold and odor-causing bacteria, but ANG coatings create a surface on these products to which mold and pathogens, such as bacteria and viruses, have difficulty adhering. Once treated with ANG, these products require less frequent cleanings, and when cleanings are necessary, ANG coatings allow most glass and ceramic surfaces to be cleaned without detergent, using water only.
