Aculon electronics coating solutions allow manufacturers to improve surface protection, solder paste release, anti-fingerprint resistance, adhesion control, underfill behaviour, and test pin reliability.
Product ranges including NanoProof^®, NanoClear^® and NanoPearl™ are designed to solve critical surface challenges across PCBs, SMT stencils, electronic components, displays, housings, and production tools.

Electronics manufacturing depends on precise surface performance. Circuit boards, components, SMT stencils, test pins, displays, housings, adhesives, and protective coatings all need to perform consistently during production and in use.
Aculon’s nano-coating technologies help manufacturers control how these surfaces interact with water, oils, solder paste, fluxes, adhesives, contaminants, and other process materials. The result is better surface protection, cleaner release, improved bonding control, reduced contamination, and more reliable production performance.
The Aculon electronics portfolio includes solutions for PCB protection, electronic-grade coating replacement, SMT stencil treatment, anti-fingerprint protection, adhesion promotion, epoxy and underfill control, test pin repellency, general repellency, and hydrophilic surface modification.
These technologies are ideal for PCB manufacturers, SMT assembly teams, electronics testing environments, component producers, and device brands looking to improve reliability, cleanliness, production consistency, and surface functionality. 

Aculon Product Range for Electronics Applications

How Aculon Electronics Coatings Work

Aculon’s electronic coatings enable tailored surface modifications for specific functions, such as repellency, adhesion promotion, anti-fingerprint performance, moisture protection, and controlled wetting. The coatings are ultrathin and designed to add surface functionality without creating a heavy coating layer. This makes them well suited to electronics applications where space, precision, weight, and component performance are critical. Depending on the product and production process, Aculon coatings can be applied using practical liquid-phase methods, such as spraying, dipping, dispensing, or wiping.

Key Application Areas

PCB Protection

Aculon NanoProof^® PCB Protection protects circuit boards and electronic components from accidental water exposure. It is designed for compact electronic devices, internal circuit boards, and assemblies where moisture protection is needed without applying a heavy coating layer. 
 

Electronic-Grade Coating Replacement

The NanoProof^® 3 Series is designed as an alternative to 3M Novec™ 1700, 1900, and 2700 electronic-grade coating series. It supports anti-wetting, anti-stiction, chemical protection, corrosion protection, and moisture resistance for PCBs and electronic components.

SMT Stencil Performance

SMT printing quality depends on clean solder paste release and consistent stencil performance. NanoClear^® SMT Stencil Nano-Coating helps improve solder paste release, print quality, throughput and fine-aperture performance. NanoPearl™ Stencil Treatment creates an oleophobic surface on metal SMT stencils, helping repel solder fluxes and reduce material buildup.

Anti-fingerprint Surface Protection

Aculon anti-fingerprint coatings reduce visible fingerprints, smudges, and oily residues on displays, touch surfaces, smartphones, tablets, laptops, housings, and other personal electronic devices. This helps maintain a clean appearance and improves the user-facing quality of finished products.

Adhesive, Underfill, and Flow Control

Aculon epoxy and underfill control coatings create nanoscale repellent barriers that help control where adhesives, epoxies, and underfills flow. This supports cleaner processing and better control around sensitive component areas. 
 

Test Pin Reliability

Aculon test pin repellency coatings aid in the reduction of contaminant buildup on POGO pins and test fixtures, supporting more reliable readings and reducing the need for frequent cleaning.

Why Choose Aculon?

Aculon develops specialist nano-coatings and surface treatments for metals, glass, polymers, ceramics, powders, semiconductors, and electronic components.
For electronics manufacturers, whether the objective is to protect a PCB, release solder pastes more cleanly, reduce fingerprints, control adhesive flow, or improve test pin reliability, Aculon creates value with practical, production-focused solutions that deliver tailored improvements to the performance dynamics of critical surfaces.
The application of Aculon creates targeted surface functionality without heavy coating buildup, enabling manufacturers to manage flexible methods to improve quality, reliability, and process consistency across electronics production.
