PROMOSOLV™ COAT Series —Replaces 3M Novec™, leading the industry with nano-thin protection technology.It provides a hydrophobic, oleophobic, and corrosion-resistant invisible barrier, enabling efficient processes that avoid obscuring the image and dry in seconds, thus comprehensively enhancing the extreme environmental tolerance of electronic products.
Even if you are using a water-based cleaning system, drying quality remains critical. Inventec’s solvent drying technology offers a more advanced and sustainable option for precision electronic components than traditional hot air drying.
Solution Highlights
- Process efficiency is maximized and simplified.
- Masking-free feature: The coating is extremely thin (nanoscale) and has conductive penetration, so electronic connectors and contacts can be dip-coated directly without prior masking, saving a lot of manual tape application and removal costs.
- Instant drying: Using a special fluorine-based carrier, it dries in less than 1 minute at room temperature, eliminating the need for expensive thermosetting ovens or UV equipment, thus drastically increasing production line turnaround time.
- Superior protection:
- Hydrophobic & Oleophobic properties: Provides an extremely high contact angle, preventing water droplets and oil from adhering and effectively preventing circuit corrosion caused by salt spray, moisture and environmental pollutants.
- High permeability: It can evenly cover the bottom space of micro-components (such as BGA), providing 360-degree protection without blind spots.
- High material compatibility:
- It has excellent adhesion to various common substrates on PCBA (plastic, metal, glass, ceramic, elastomer) and will not cause swelling or damage to parts.
- Application Flexibility:
- It supports dip coating, selective spray coating, or brush coating, and can provide different solid contents (such as 2% or 4%) to adjust the coating thickness according to needs.
Advanced Electronic Protection Ultra-Thin Coating Guide
Ultrathin coatings are extremely thin protective layers (typically less than 10 micrometers) applied to electronic components, sensors, and assemblies to ensure long-term reliability without compromising quality or functionality. They protect against moisture, corrosion, contaminants, and electrical leakage while maintaining full electrical and optical performance.
These coatings are based on fluoropolymers or silicone chemistry and can be applied through methods such as dip coating, spraying, or selective coating. Their low viscosity and self-leveling properties allow them to easily penetrate complex geometries, often without the need for masking, enabling faster and more sustainable production processes.

Benefits and Applications
Core advantages
Ultra-thin coatings offer excellent moisture and ionic contamination resistance while maintaining good electrical resistance, optical transparency, and thermal stability. They reduce mask requirements, increase production efficiency, and are compatible with environmentally friendly production lines.
Technical aspects
Ultrathin coatings, typically ranging from 100 nanometers to 10 micrometers in thickness, provide uniform coverage and exhibit strong adhesion to metals, glass, and polymers. They can be hydrophobic, oleophobic, dielectric, or corrosion-resistant, and are generally non-flammable and free of volatile organic compounds (VOCs), making them safer for industrial applications.
Application areas
Ultra-thin coatings are ideal for consumer electronics, automotive sensors, aerospace electronics, medical devices, and optical components because these applications have high requirements for reliability and minimal film thickness.
