Generally about nanotechnology surface treatment

Q: What chemical solid is used to make NanoProm coatings?

SiO2 (silicon dioxide), which is primary ingredient of glass.

Q: Are NanoProm coatings dangerous or harmful to the environment?

No, they are safe for food and environmentally friendly. SiO2 is an inert substance that surrounds us in nature. It is thus a "basic element" in nature.

Q: Are the coatings breathable?

Yes.

Q: How can it be that a permanent coating can hold on elastic surfaces like textiles without breaking?

The SiO2 layer on the substrate surface is so thin (100 nanometers) that elasticity is guaranteed without changing the look, feel or other properties of the textile .

Q: Is the name "Nano" protected?

No! Unfortunately, manufacturers of low-quality and outdated technologies are also trying to ride the "Nano" wave. Nano is only a unit of measurement. Layer thicknesses below 100-200 nm are normally referred to as nano technology. Caution: There are many companies that write "Nano" on their products that have nothing to do with SiO2 or TiO2!

Q: What is the difference between quality Standard and Plus+?

The difference is in the amount of active ingredients, which make the hydrophobia and other positive properties. Quality Plus+ contains in some case more than twice as much nano particles.

Q: Are there health risks?

No! In their hardened state, NanoProm coatings are even safe in food. The water-based systems can be applied anywhere without concern. For solvent-based systems, we recommend an exhaust hood for spray applications and rubber gloves for manual application by cloth.

Q: Are NanoProm products environmentally friendly?

Yes! No hazardous substances are created during production. Nano products also create enormous cost savings in the field of cleaning and the use of chemical cleaners.

Q: Do I need to pay attention to the weather when I want to apply a coating outside?

Water-based products should not be used below 2° C. It should not be raining during application. During 24 hours after application, the surface must not come in contact with chemicals and must not be mechanically strained.

Q: Do NanoProm products need to be specially protected during shipping?

Water-based systems should not be shipped or stored below the freezing point.

Storage and handling

Q: How long do NanoProm products last in the bundle?

The guaranteed storability is 6 months; however, based on our experience, we report that no product changes occur even after 1-2 years

Q: How to store NanoProm products?

Some products are ethanol-based and thus hazard materials. All areas of filling must thus be explosion-protected. No smoking, be careful with fire and open flames. Store during temperatures above 5 degrees.

Q: Is it necessary to wear protective clothes when manipulating with coatings?

The main NanoProm products are not harmful to health. Nonetheless, we recommend wearing gloves when handling chemicals.

Back

Glass and ceramics

Q: How long is functionality guaranteed?

Since the coatings are UV-stable, functionality is possible over longer periods of time (beyond 10 years). Prerequisites are no abrasion and no use of strong chemicals for cleaning.

Q: How does the coating handle abrasion or chemicals?

Coatings for all surfaces are characterized by strong abrasion- and chemical-resistance. Chemical resistance: pH value 1-12.5
Abrasion resistance on glass: after 10,000 wiper cycles = performance reduction of 10-20%

Q: What applications does NanoProm recommend?

Shower cubicles, sinks, toilets, solar panels, mirrors, windows, car windows, winter gardens...

Q: Is the coating food-safe?

Yes, as confirmed by an CBA certificate.

Q: How fast is the coating stable after the application?

The water-resistance is guaranteed only minutes after application. Packaging/storage of the substrate can even be started right after application. Abrasion and chemical resistance should first be tested after 24 hours since a post-crosslinking of the product takes place.

Q: Does the coating impact the visual appearance?

No! Because of the small layer thickness (100 nanometers), there is no impact on visual appearance or feel of the substrate.

Q: Does the coating impact the UV irradiation on solar panels?

No! Because of the small layer thickness (100 nanometers), there is no impact on UV irradiation.

Q: Can the coating be reapplied?

Yes, in the case of damage e.g. through permanent abrasion, it can be reapplied like an initial application.

Q: Can two coats be applied?

! A 2nd coating will not adhere to the 1st coat!

Q: How much is used per m²?

Industrially: 10-15 ml/m². Manually: 5-10 ml/m².

Q: What cleansers can be used to clean the substrate before application?

Any type, as long as all cleanser residue can be removed!

Q: What cleansers can be used to clean the substrate after application?

We recommend pH-neutral cleansers (also those containing tenside).

Q: The beading effect is not working all of the sudden.

The coating is probably dirty. Dirt particles on the coating prevent beading. Just clean and the effect will return.

Q: After applying to my car windshield, there is no beading effect

Was your car washed before application? It could be that cleanser residue or silicon oil was on the windshield during coating. In this case, a nano product cannot adhere. Workaround: Clean with an abrasive cleaner such as ceroxide and reapply.

Q: What are the main advantages of a nano-glass/ceramic coating compared to competitive products?

Permanence: Chemical and abrasion resistance, UV stability, low m² price (consumption is only 5-10 ml per m²)

Q: Streaks are visible after application by hand.

These streaks represent material excess. For this reason, we recommend polishing with a dry and clean cloth until the surface is completely dry!

Q: I only noticed these streaks after 24 hours.

Just repolish the coating with a little bit of coating – until it is completely dry. This will remove the streaks.

Q: A glass/ceramic coating protects against what adhesions?

A glass/ceramic coating generally protects against all adhesions. It prevents permanent bonding of the contaminant on the glass surface. Coated substrates are thus easier to clean.

Attention: In the case of particularly thick contaminants, such as dried toothpaste residue in the sink, the upper layers of the toothpaste ("toothpaste on toothpaste") must first be removed before the actual easy-to-clean effect can be detected ("toothpaste on coating").

Stone, mineral and porous surfaces

Q: How long is functionality guaranteed?

Since the coatings are UV-stable, functionality is possible over longer periods of time (beyond 10 years). Prerequisites are no abrasion and no use of strong chemicals for cleaning.

Q: How does the coating handle abrasion or chemicals?

NanoProm coatings are characterized by strong abrasion- and chemical-resistance. Chemical resistance: pH value 1-12.5 Abrasion resistance on mineral substrates depend on the resistance of the substrate. Principle: If the surface is destroyed, the coating is also destroyed

Q: What applications does NanoProm recommend?

Facades, monument protection, bridges, concrete blocks, terra cotta, cobblestones, bathroom tiles.

Q: Is the coating food-safe?

Yes, as confirmed by an CBA certificate.

Q: How fast is the coating stable after the application?

The water resistance is guaranteed after complete drying. Packaging/storage of the substrate can even be started right after application. Abrasion and chemical resistance should first be tested after 24 hours since a post-crosslinking of the product takes place.

Q: Does the coating impact the visual appearance?

No! Because of the small layer thickness (100 nanometers), there is no impact on visual appearance or feel of the substrate.

Q: Does the coating influences the permeability of the surface?

No.

Q: Can the coating be reapplied?

Yes, in the case of damage e.g. through permanent abrasion, it can be reapplied like an initial application.

Q: Can two coats be applied?

Yes, e.g. in order to ensure that no spots were missed. It must be coated wet-in-wet, i.e. before drying of the substrate.

Q: Can I apply a new wall color to the facade after a nano-coating?

Yes. The hydrophobic properties impact the contact of the color on the wall but only slightly. We recommend applying the pain using a roller.

Q: How much is used per m²?

Between 80 and 200 ml per m² - depending on the absorbency of the substrate.

Q: What cleansers can be used to clean the substrate before application?

For mineral substrates, we do not recommend the use of cleansers. A thorough cleaning with a pressure washer (distance 30 cm) is however allowed.

Q: The beading effect is not working all of the sudden

The coating is probably dirty – Dirt particles on the coating prevent beading – Just clean with a pressure washer and the effect will return.

Q: After applying to a mineral surface, there is no beading effect.

The surface was probably already treated with another product.

Q: What are the main advantages of a nano-coating for mineral substrates compared to competitive products?

Permanence: UV stability, chemical resistance.

Q: Does the product protect mineral substrates from acids?

No! This is not possible with the current state of the art.

Q: Can a plastered or painted facade be coated?

In general: If the main component of the paint is mineral: yes! If not: no!

Q: A coating for mineral substrates protects against what adhesions?

A coating for mineral substrates protects against deposits from air pollutants, prevents the formation of mosses through hydrophobia. Large portions of dirt are washed off by rain – but a small percentage remains.

Q: Does the NanoProm coating provide thermal insulation on house walls?

It was not generally developed for thermal insulation. But the coating protects the wall from moisture, which reduces the insulation degree of the wall. Thus, the coating receives the natural insulation rate of the wall.

Textile, leather and wood

Q: How long is functionality guaranteed?

Since the coatings are UV-stable, functionality is possible over longer periods of time counted in years. Prerequisites are no abrasion and no use of strong chemicals for cleaning. Principle: If the fiber is damaged, the coating is also damaged.

Q: How does the coating handle detergents and is it machine washable?

Test result with conventional detergent (Tandil): Quality Standard: 20-30 washings (washing machine), Quality Plus+: 30-50 washings (washing machine).

Q: What applications does NanoProm recommend?

Any type of textiles (cotton - silk - suede - synthetic threads, etc.)

Q: Is the coating food-safe?

Yes, as confirmed by an CBA certificate.

Q: How fast is the coating stable after the application?

The water resistance is guaranteed after complete drying. Packaging/storage of the substrate can even be started right after application. Abrasion and chemical resistance should first be tested after 24 hours since a post-crosslinking of the product takes place.

Q: Does the coating impact the visual appearance or feel?

No! Because of the small layer thickness (100 nanometers), there is no impact on visual appearance or feel of the substrate.

Q: What cleansers can be used to clean the substrate after application?

Conventional detergents.

Q: The beading effect is not working all of the sudden.

Is there detergent residue on the textile after washing? Tensides interfere with the beading effect -> swivel out with clean water.

Q: After applying to a textile, there is no beading effect!

Detergent residue probably prevented the adhesion of the textile coating on the thread. -> Rinse the washed textiles with clear water before coating.

Q: What are the main advantages of a nano-coating for textiles compared to competitive products?

Permanence: UV stability, washing machine and detergent resistance, breathability.

Q: Can a printed textile be coated?

Yes.

Q: A coating for textiles protects against what adhesions?

A coating for textiles protects against moist contaminants. It also prevents the penetration of dirt into the threads and guarantees the easy dissolving of dirt particles.

Plastics and lacquered surfaces

Q: After coating a plastic, you can't tell the difference between the uncoated substrate.

Additives that trigger a beading effect can be used in the production of plastics. In this case, they should be removed through plasma treatment. After a longer period of time, these additives break down on their own since they are usually not UV-stable. Principle: It is better to coat an older plastic than a new plastic!
