NANO Surface Treatments

On the nano scale, matter operates at the one-billionth-of-a-meter level. It is the scale of atoms and molecules and no doubt, nanotechnolgy has significantly changed many things in our lives, one now being corrosion resistance. If a part can effectively be sealed off from its environment – even by a billionth of a meter – then one can have outstanding properties.

We offer the following for Nano-based treatments   

 

Release Coating

LHS Spectra Treated, RHS untreated

Release Coating

  • SpectraNano Release Coating

SpectraNano forms a complete seal and leaves the treated surfaces highly hydrophobic. Spectra shows very good release properties when moulding “sticky” materials such as polyurethanes but it works well with conventional plastics, and any other surface that has to repel liquids and show good release properties. The coating can withstand temperatures up to 300°C. Spectra is hardened by heat curing and this gives it good wear resistance.  

The picture shows Spectra used on an injection moulding die also provides high corrosion resistance (LHS) compared to the untreated section (RHS).

For injection moulding dies special pre-cleaning procedures need to be followed as parts must be free from any contamination. It is advisable to dry ice blast dies clean before sending for Spectra. More on dry ice blasting in South Africa here.

Corrosion resistance

  • Nano Super Anti-Corrosion (NSAC)

Seals the surface with a tough, durable nano-sized layer AND also repels liquids due to a hydrophobic effect (i.e. liquids will bead rather than wet the surface). NSAC has a very high viscosity and thus penetrates easily into microscopic cavities and hard-to-reach places. It displaces moisture at the nano level and the stable, invisible layer protects metals from oxidisation and corrosion. Suitable for all environments including industrial, marine corrosion and electrical systems. NSAC is particularly useful to avoid rust on parts and tooling that have to be transported by sea.

The application process is simple: 

  • remove rust and macro contaminants
  • degrease (we recommend Nanoworks Heavy Duty Cleaner for degreasing as this also works at the nano level!)
  • quick wipe with dry cloth
  • immediately apply NANO Super Anti-Corrosion until surface is evenly covered
  • leave for 24 hrs to allow protective film to form

 

  • Nano Premium Dry Shield   

A solvent-based corrosion resistant treatment that leaves a dry surface. Specially for protection against corrosion, humidity and insect/animal contact on PCB’s and other sensitive electronic equipment.

  • Premium Agri & Outdoor

A higher efficiency in muddy environments, such as agricultural environments as well as the outdoor and construction.
