NanoProof 1.0 PCB Waterproofing Surface Treatment
Harmonization Code : 2901.10.00.00 | Acyclic hydrocarbons; Saturated
Main features
- Provides basic protection for accidental water damage
- 10-100 nm thickness
- IPX3
Product Description
NanoProof 1.0 is a nanoscale surface treatment designed to impart hydrophobicity and reduced friction to circuit boards and electronic components. It is a simple, one-step process that provides basic protection for accidental liquid contact, IPX3.
NanoProof 1.0 is safe to use, and the dried film is PFAs free, nontoxic, nonflammable, and nonconductive. The treatment can adhere to a broad range of substrates and does not change the appearance of the surface (100% Visible light transmission) at <20 nm thickness.
Advantages of Aculon's NanoProof 1.0
- IPX3
- Very forgiving in application / reworkable
- Extremely flexible
- No cure required
- Handleable when dry
- Contains UV tracer
- RoHS and REACH compliant
- PFAs Free
Utilization of multiple options
Please note that many customers have found significant success utilizing two or more of the available NanoProof® technologies. Often times the most sensitive components benefit from the most robust NanoProof® technology (5.1) while the remaining components can be coated with the less robust coatings to benefit from their electrical push-through capability, flexible nature, and lower costs.
Detection/Inspection
All NanoProof products contain a UV Tracer which is visible under 365nm wavelength UV light (Detectable by both the human eye and automated detection systems). Please note that solder masks and other substrate materials containing a UV tracer may make accurate detection of NanoProof difficult.

How to apply NanoProof 1.0
|
STEP 1 ⇨ CLEAN |
STEP 2 ⇨ TREAT |
STEP 3 ⇨ DRY |
| Parts must be sufficiently clean before treatment for proper bonding and effective application. This can be accomplished by first degreasing the surface with solvents/rinsing with IPA. |
Dip - Fully immerse the part in the treatment solution for 1 minute. Withdraw the part at a steady rate to ensure even coverage. Allow to air dry. |
To dry, the part should be placed at room temperature until the solvent is evaporated. It should leave an oily coating that is deformable to the touch. In some cases, additional thermal treatment (e.g. 100C for 5 minutes) will speed solvent evaporation.
|
|
Spray - Spray the solution on the substrate, air dry. If the coating is too thick, reduce the amount applied by changing the settings on the spray gun or using a diluent. |
||
|
Dispense - Dispense the treatment over the surface, applying enough to coat the entire surface. Allow excess material to drain. |
Application Tips
- In some cases, Kyzen cleaners like Ionox I3s416 or Cybersolv 141-R may be appropriate for removing surface contamination.
- For dip applications, dip containers should be stainless steel, glass, or aluminum. Plastic containers are likely to contaminate the solution.
- Use a microfiber cloth to wipe after cleaning.
- Coat the substrate as soon as possible after cleaning to prevent recontamination.
- Spray Equipment Suggestion
- Spray & Dispense Valve - The PVA FCS300 Valve has been tested and confirmed compatible with all NanoProof products.
- Manual Coating System - The PVA MCCS-SYS-1 Manual Conformal Coating System has been tested and confirmed compatible with all NanoProof products.
- Automated & Selective Coating - The PVA Delta 8 Selective Coating / Dispensing System has been tested and confirmed compatible with all NanoProof Products.
- Cure temperatures and conditions should be optimized based on substrate and durability requirements.
How to test for Hydrophobicity
To test for hydrophobicity, allow water droplets to fall onto the surface, which should bead up to a contact angle >90⁰. If the contact angle is <90⁰, then the surface is not
hydrophobic. The surface should be cleaned again and the treatment reapplied.
