3M™ Novec™ Electronic Coating Replacements

NanoProof® protects against water and moisture damage, demonstrating great durability under exposure to oxygen/light. NanoProof® does not add durability against physical abrasion.

While we have had some customers successfully apply NanoProof® over No-Clean Flux we do not recommend it. The No-Clean flux can prevent proper bonding resulting in delamination and in comparative testing of NanoProof® treated board with & without flux the “without flux” boards universally perform better.

NanoProof® 3 offers IPX Level 5/6.

Target coating thickness is greatly application dependent. Contact an Aculon® representative today to discuss your specific application parameters.

NanoProof® 3 will show water contact angles greater than 110° and oil contact angles greater than 70°.

NanoProof® 3 does not require heat curing.  This coating cures (tack-free) at room temperature in less than 5 minutes.

This depends on many factors including: your part size, desired protection level, keep out areas, throughput required, among other things. No easy answer. NanoProof® 3 is designed for dip, spray, and needle dispense applications. Contact an Aculon® representative or your distributor to discuss best application methods.

Detect all UV Tracers with a 365 nm UV lamp.

Yes, numerous OEMs/CMs use these materials in production around the world. Due to confidentiality, we cannot reference customer names. Aculon® has established distributors such as Ellsworth Adhesives and Caplinq. These products are commercially available and commercially used.

Every standard version of NanoProof® includes a UV Tracer. The UV Tracer utilized is visible under a 365 nanometer light. For QC purposes, the treatment illuminates blue under the UV lamp which gives an indication of how well you have treated your parts. For qualification purposes it is also possible to test viability utilizing SIR tests and cross sectioning to ensure consistent coverage.

We have not found any negative impact. UV Tracer-free options are available. Please inquire for information.

Recommended storage is in a cool, dry environment (less than 40°C).

Keep containers tightly sealed.

Keep out of sunlight or heat sources.

Shelf life for this product is 2 years from the manufacture date in a sealed container.

No specific equipment required.  Aculon® has a strong relationship with equipment manufacturers such as Nordson, PVA, etc.

For NanoProof® 3, the carrier is a fluorosolvent blend.

Over applying NanoProof® 3 may lead to cracking or blistering.

There is always to solvent trapping. However, these materials are low enough concentration and the material does not skin over, making solvent trapping highly unlikely.

No. These coatings are nonflammable/non-toxic and do not require fume hoods during application.

NanoProof® 3 may delaminate or apply unevenly on epoxy.

For NanoProof® 3, the treatment will likely need to be removed to solder. Most choose to utilize selective deposition in these situations to avoid treating the solder pad all together. Carrier solvents are also available to remove the coatings.

Yes. All Aculon® products are REACH/RoHS compliant.

The NanoProof® 3 products are all non-flammable and non-toxic and can ship non-DG. NanoProof® 3 is VOC-exempt in certain countries.

Ideally, the boards are contaminant-free before treatment application. If there is no clean flux, we recommend using a cleaner. Dust and debris may be removed using air pressure.

The products are manufactured at our facility in California. Aculon® has large distributors in North America, Europe, and Asia. Buying directly from Aculon® is also available.

Yes. Masking is not required but can be implemented.

Yes, if less than 1um thick.

You will not want to coat contacts.  This coating is insulative and may create impedance.

There are no supply chain risks for these engineered fluids. We have ensured multiple sources for the carrier solvents and raw materials.

Yes.  NanoProof® 3 can coating nearly all surfaces, with the exception of fluorinated materials

Yes, solvent can be used to clean questionable areas and then the treatment can be reapplied as desired. If appearance is not a concern then a simple coating reapplication should work.
