Multi Surface Hydrophobic Treatment

Harmonization Code : 2901.10.00.00 |   Acyclic hydrocarbons; Saturated
Main features
  • General purpose hydrophobic treatment
  • 20-100 nm thickness
  • Repels most aqueous liquids

Product Description

Aculon's Multi-Surface Hydrophobic technology is designed to make many surfaces repellent to water and other water-based fluids. The hydrophobic treatment is quick and easy to apply, optically clear, and ultra-thin. It can reach a thickness anywhere from 20 nm to 100 nm and reduces the friction of the surface without altering its appearance. Aculon's Multi-Surface Hydrophobic Treatment can even be applied via several application methods that do not require capital equipment investments, including dip, wipe, or spray.

Advantages of Aculon's Multi-Surface Hydrophobic Treatment

  • Repels liquids from many different metals, polymers, textiles, paper, etc.
  • Lowers the coefficient of friction of surfaces
  • Uniform thickness
  • General purpose and multi-surface treatment
  • Easily reapplied in the field if damaged/reworkable

Specific Gravity
Specific Gravity
Specific gravity (SG) is the ratio of the density of a substance to the density of a reference substance; equivalently, it is the ratio of the mass of a substance to the mass of a reference substance for the same given volume.

For liquids, the reference substance is almost always water (1), while for gases, it is air (1.18) at room temperature. Specific gravity is unitless.

Shelf Life
Shelf Life
Shelf life is the amount of time after manufacturing that a product is guaranteed to retain its properties.

It differs vastly per product and it is based on temperature and storage conditions.

The properties can be guaranteed for the temperature and time range indicated on the TDS since those are the ones tested to be the best for the product.
Shelf Life @ 15°C 24 months
Physical Properties
Viscosity
Viscosity
Viscosity is a measurement of a fluid’s resistance to flow.

Viscosity is commonly measured in centiPoise (cP). One cP is defined as
the viscosity of water and all other viscosities are derived from this base. MPa is another common unit with a 1:1 conversion to cP.

A product like honey would have a much higher viscosity -around 10,000 cPs-
compared to water. As a result, honey would flow much slower out of a tipped glass than
water would.

The viscosity of a material can be decreased with an increase in temperature in

Flash Point
Flash Point
The flashpoint of a solvent is the lowest possible temperature at which it can vaporize to form an ignitable vapor.

Flashpoint is often confused with “autoignition temperature”, which is the temperature at which a solvent ignites without an ignition source.

How to apply Aculon's Multi Surface Hydrophobic Treatment

STEP 1 ⇨ CLEAN

STEP 2 ⇨ TREAT

STEP 3 ⇨ DRY

For this technology, cleaning is not typically required but is recommended. To clean, remove any visual dust, dirt, and grime that could damage the surface.

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 dry or cure, then wipe clean with a microfiber cloth.

 

Air dry at room temperature until the surface is dry to the touch.

In some cases, additional thermal curing (e.g. 100°C for 5 minutes) may boost performance.

 

 

Wipe - Using a clean cotton cloth, wet it with the solution then rub the substrate for 10 seconds, air dry, then wipe clean with a microfiber cloth.

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.

 

 

Application Tips

  • In some cases, additional thermal curing ( e.g. 100°C for 5 minutes) may boost performance.
  • Inkjet printing or roll coating can also be used to apply the treatment.
  • Spray Equipment Suggestions: HVLP(Binks Mach 1), HVLP(Devilbiss JGHV), Air Atomization(Devilbiss MBC gun), and Airless(Graco Model 225-292 President Pump Series A).

 

 

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 Multi Surface Hydrophobic Treatment reapplied.
