Medical devices do not get second chances. A moisture-damaged PCB inside a cardiac monitor, a contaminated bonding surface on a diagnostic cartridge, a fouled sensor in a lab instrument, these are not just manufacturing defects; they are patient risks. The question is not whether to protect your device surfaces. The question is how to do it without compromising the design you spent years perfecting.
Aculon's nanoscale surface modification technologies answer that question. Available through ChemPoint across the EMEA region, they protect, bond, repel, and control surfaces at the molecular level; invisibly, efficiently, and without changing what your device looks like or how it fits together.

Protection That Works at the Nanoscale

Aculon's core insight is that surface performance does not require thick coatings. Their technologies interact directly with the substrate at the molecular level, creating hydrophobic, hydrophilic, adhesion-promoting, or antifouling surfaces intrinsic to the material interface, not sitting on top of it. No vacuum chambers. No cure cycles. No redesigning around a coating.
For medical device manufacturers, that means adding critical surface functionality without adding compliance headaches, dimensional changes, or process disruptions.

The Aculon Product Range

Aculon offers a broader toolkit than most surface coating suppliers. While others offer a single chemistry for a single problem, Aculon's range covers the full spectrum of surface challenges encountered across medical device design and manufacturing.

NanoProof^® Series for Moisture and Environmental Resistance

NanoProof^® is Aculon's flagship electronics waterproofing line, delivering moisture and environmental resistance up to IPX8 (submersion depths beyond one metre). Built on Aculon's proprietary Transition Metal Complexate (TMC) chemistry combined with fluorinated acrylic polymers, NanoProof^® creates a hydrophobic and oleophobic barrier across metals, polymers, glass, and semiconductors without masking, curing, or batch processing.

These products are applied by spray, dip, or flow coat in line with no cure and no masking needed. UV tracer dye options support full process verification. They contain no RoHS or REACH SVHC compounds.

NanoClear^® for PCB Integration and Packaging

NanoClear^® is a stencil coating technology that improves solder paste print quality and reduces defects during PCB assembly. In medical electronics manufacturing, where yield and traceability are non-negotiable, NanoClear^® helps maintain consistent print performance across the stencil surface, reducing bridging, smearing, and aperture clogging that compromise board quality and downstream reliability.

Adhesion-Promoting Nano-coatings for Bonding and Packaging

Adhesion is everything in medical device assembly. Whether bonding substrates in a diagnostic cartridge, encapsulating a sensor, or laminating packaging films, surface energy determines whether the bond holds. Aculon's adhesion-promoting nano-coatings modify surface chemistry to enhance bonding characteristics on metals, polymers, and glass without primers, plasma treatments, or aggressive surface preparation that can damage precision components.

Hydrophobic, Oleophobic, and Omniphobic Coatings for Wafer Handling and Contamination Control

For applications where surfaces must actively repel water, oils, and mixed contaminants, Aculon's range of repellent coatings offers more than simple water resistance. Omniphobic formulations repel both aqueous and nonaqueous fluids, which are critical in wafer handling, microfluidic devices, and any medical application where cross-contamination between samples or reagents must be controlled at the surface level.

Hydrophilic Coatings for Bonding and Fluidic Applications

Not every medical surface should repel liquids. Hydrophilic coatings from Aculon enhance wettability and promote capillary action making them valuable in diagnostic assay devices, lateral flow platforms, microfluidic channels, and catheter surfaces where consistent, predictable fluid movement is essential to device performance. The same nanoscale precision that makes Aculon's repellent coatings effective applies here in reverse: controlled wetting, exactly where it is needed.

Antifouling Coatings for Contamination Control and Yield Improvement

Organic and inorganic buildup on device surfaces degrades performance over time, blocking sensors, fouling flow channels, and reducing the accuracy of diagnostic readings. Aculon's antifouling coatings prevent this accumulation, extending operational life and protecting measurement integrity in biosensors, diagnostic instruments, and any device where surface cleanliness directly affects output quality.

Where These Technologies Make a Difference in Medical

Wearable Medical Electronics: Continuous glucose monitors, cardiac patches, and body-worn sensors live against the skin. NanoProof^® 5.0 has been validated for resistance to 100+ hours of sweat immersion, making it purpose-built for this environment, with no trade-off on device dimensions or flexibility.
Hearing Instruments: The ear canal is one of the harshest moisture environments any electronic device encounters. NanoProof^® has an inline application that fits naturally into high-volume hearing instrument manufacturing no batch bottlenecks and no capital-intensive equipment.
Diagnostic Devices and Lab-on-a-Chip: Hydrophilic coatings drive consistent fluid flow in lateral flow assays and microfluidic channels. Antifouling coatings protect sensor surfaces from biofouling. Adhesion promoters ensure that laminated layers and bonded substrates remain together during thermal cycling and reagent exposure.
Surgical and Diagnostic Equipment: Repeated disinfection with aggressive agents degrades surfaces over time. Aculon's repellent and antifouling treatments help device housings and instrument surfaces maintain their integrity through thousands of cleaning cycles.
PCB Assembly in Medical Electronics: NanoClear^® stencil coatings improve print quality and reduce defect rates in the PCB manufacturing step that underpins every electronic medical device, from patient monitors to implantable device programmers.
