Frequently Asked Questions

1. What care and maintenance do DFI protective coatings require?

A lot less than if the surface wasn’t protected with a DFI coating! Up to 90% less! And no harsh, expensive, polluting chemical cleaners are required, ever!

As described in the answer to How long do DFI protective coatings last?, maintenance and care vary substantially according to the type of application and the abrasion to which the treated material is exposed. Abrasion means any mechanical or non-mechanical force affecting the treated product.

In the vast majority of applications, if a few spots appear, they can be removed simply with clear water and a soft cloth or nylon body puff. Just wet the surface and use the cloth or puff to rub the surface in a circular motion. You should feel the places that are “sticky” going back to slick again. Then rinse or spray the surface with more, clean water. Wipe dry or let drain and pat dry any remaining droplets. Doing this once per month is all it takes to maintain the warranty for shower door applications, for example.

If you’ve failed to do this basic maintenance, all is not lost! See the answer to What if I haven’t done the basic maintenance?

If you have questions about a specific application, please fill out the contact form on the right or contact your DFI Reseller for the specific maintenance recommendations.

2. Do I need to use Revitalizer to maintain my warranty?

No. If you are good about doing the basic maintenance (see What care and maintenance do DFI protective coatings require?), you do not need to use DFI Revitalizer to maintain your warranty. However, the advantage of using Revitalizer is that you can ensure your DFI protective coating will last forever, literally! If you ever see the repellency of your coating wane, applying Revitalizer according to the instructions will return the performance back to “like new”. If you always do this as needed, even DFI’s basic Clear-Fusion™V coating will last forever.

3. What if I haven’t done the basic maintenance?

If necessary, you can use DFI’s Restoration Powder and a soft cloth or nylon body puff to remove any spotting that won’t come off with water and the soft cloth or puff alone. Simply apply a small amount of Restoration Powder to the cloth or puff, apply a bit of water and, USING A LIGHT TOUCH, rub the sticky or visibly stained areas to remove. If the stains still don’t come off, use our special White Scrubber Pad and Restoration Powder.

After removing the stains and assuring good ventilation in the area, apply DFI Revitalizer to the previously stained area according to the directions. This will bring the water and oil repellency back to “like-new” performance.

Warning: Using too much pressure with DFI’s Restoration Powder can damage the DFI coating. So please be careful.

You can find all these items in DFI’s handy starter Express Care Kit and larger Consumer Maintenance Kit.

4. What cleaning products are recommended for DFI protective coatings?

One of the great benefits of DFI’s protective coatings for you, your pocketbook and the environment is that you don’t need to buy harsh chemical cleaners to keep your protected surface clean. DFI recommends using only clean water and a nylon puff every two to four weeks. Simply wet down the surface wipe it down with the puff. That will do it!

If you would really like to buy a cleaning product, in addition to our DFI recommended maintenance products, the following cleaners may be used:

-            Ammonia Free Windex®
-            Sprayway®
-            Simple Green®
-            Diluted vinegar with water (1:3)

5. What is the difference between all of DFI’s protective coating products?

DFI’s protective coatings include:
Diamon-Fusion® ULTRA™
Diamon-Fusion®
Clear-Fusion™ Pro
Clear-Fusion™V

The difference between these coatings is durability and performance, ranked from top to bottom, with the top being best. While each will last years, depending upon the application (see How long do DFI protective coatings last? below), our better coatings will perform better over that time and will require less maintenance. By perform, we mean impart to the surface all of the benefits you love from our coatings, including water and oil repellency, stain resistance, ease of cleaning, impact and scratch resistance, increased brilliance, and a host of other benefits. As such, each product has a different warranty. If you’d like a more in-depth analysis of the differences, you can view a detailed comparison of these coatings here.

6. How long do DFI protective coatings last?

This answer will vary substantially according to the type of application (treated surface type and location/exposure) and the abrasion to which the treated material is exposed. Abrasion means any mechanical (such as windshield wiper on an automobile) or non-mechanical force (such as wind or dust) to which the treated surface is exposed.

For example, a treated automobile windshield in a snowy environment (where salt and sand are spread on the roads and then kicked up onto the windshield) will require a higher level of maintenance and care than a treated exterior of a building in a mild climate. And both will require much less maintenance and care and be beautiful longer than an untreated equivalent!

The great news is that all DFI protective coatings can perform forever with the proper maintenance and care. While your coating will perform as guaranteed within its respective warranty, the as-needed use of DFI’s Revitalizer can extend the life of your coating and the surface it protects literally forever. Please keep in mind that Revitalizer is not necessary in order to satisfy the basic maintenance requirement of any of our warranties, but if you want your coating to last and last, it is a great option to have.

7. Can DFI coatings be applied to my building or in my home after the glass, granite, tile or porcelain has been installed?

Yes. DFI coatings can be installed in the factory, shop or on-site. We pride ourselves in providing highest level of industrial flexibility in the industry, meaning that we have the right application process for any job, from high-volume factory systems that deliver the most efficient application process on the planet, all the way to single-application systems for custom jobs by trained professions, and even a Clear-Fusion™V Do-It-Yourself Kit for those who don’t mind putting in the work to complete the job themselves.

If you are applying DFI’s protective coatings to existing glass, we recommend that you thoroughly clean and dry completely the glass to be treated. A small amount of DFI’s Glass Rescue™ or Restoration Powder and water is ideal for this but other glass cleaners are acceptable. A non-abrasive nylon scrubber will also help remove unseen contaminants.

If you’d like to have your home or building protected, please fill out our Home or Building contact form and we’ll connect you with an Authorized DFI Applicator in your area.

8. On what surfaces do DFI protective coatings work?

The nanotechnology in DFI protective coatings chemically reacts with most silica-based surfaces such as glass, ceramic tile, granite, porcelain and quartz, as well as other products that contain silica.

9. Why is Diamon-Fusion® not applicable on plastics or metals? Do you have any other products that are compatible to plastics or metals?

The molecules of plastics and metals do not contain silicon dioxide (silica), which is required for the molecular bond of our protective coatings to occur. We have developed some new basic coatings that enhance the look and feel of stainless steel, plastic and wood laminates under the Defender Series brand.

10. How does the Diamon-Fusion® process work?

DFI's flagship protective coating is patented around the world and branded under the Diamon-Fusion trademark. It uses a two-stage nanotechnology process. The chemical reaction created in the first stage causes a "cross-linked" and "branched" ultra-thin silicone film to be grown from below the surface out. The second stage 'caps' the entire chain of atoms. This unique 'capping' substantially increases the hydrophobicity and durability, leaving, chemically speaking, no points of attachment for contaminants and creating a truly repellent charge. Through simple neutralization, all chemicals become inert within a few seconds. No curing time is needed since the chemical reaction itself occurs in less than 2 seconds.

The resulting coating is an ultra-thin protective layer of optically clear material which makes the surface significantly easier to clean and resistant to weathering. The method is done at nano-scale levels, which is a length scale ranging from approximately 1 to 100 nanometers (1 nanometer is 1 billionth of a meter). For comparison, the thickness of a human hair ranges from 40,000 to 100,000 nanometers.

The bond created in the patented process is a covalent bond. A covalent bond means that the coating actually shares electrons with molecules in the glass itself, thus becoming part of the glass. Covalent bonds are approximately 10 times stronger than hydrogen-bridge bonds, which are commonly used in most other water repellent coatings.

11. Once treated with the Diamon-Fusion® process, will I still need to clean my glass, tile, porcelain or granite?

Yes, you will. The Diamon-Fusion coating REDUCES cleaning time but it does not eliminate it entirely. Diamon-Fusion is similar to the development of Teflon®* for cooking pans. While you can cook food in uncoated pans, it is so much easier to clean up if you cook with Teflon coated pans. Just as your Teflon-coated pan needs an easy cleaning, so too will your DFI protected surface need an occasional easy cleaning.

12. How much does it cost to have a glass surface or a kitchen granite counter top treated with Diamon-Fusion?

Prices are determined by DFI Resellers according to their own business strategies and market segments. We are a technology developer and supplier and legally cannot set retail prices. Although prices do vary substantially depending on geographical areas and markets, Diamon-Fusion® has proven to provide the best combination of price and performance of any easy-to-clean coating for silica-based surfaces available in the market today.

13. Is DFI Nanotechnology environmentally friendly?

Yes. In fact, DFI Nanotechnology provides a great benefit to the environment. All DFI coatings are applied using environmentally safe scientific processes. The chemicals used in our patented processes have been in used for decades in different applications in a variety of industries worldwide and are not found in the U.S. Clean Air or Clean Water Acts. DFI has a blanket approval for our “zero emission” application process from the South Coast Air Quality Management District in Southern California, one of the most stringent air quality management agencies in the world. There are also no Permissible Exposure Limits set by the U.S. Occupational Safety and Health Administration. Rooted in our eco-friendly philosophy, we have implemented the highest standards in the handling of our chemicals to ensure our use is safe for the environment.

Once applied, DFI Nanotechnology eliminates the need for polluting chemical cleaners and reduces the frequency of cleaning necessary, thus reducing the amount of water wasted to perform that cleaning. Both of these have a profound impact on the environment, reducing the demand on our over-burdened fresh water supplies and saving our rivers, lakes and oceans from polluting run-off.

14. What does "contact angle" mean?

The contact angle, also called "wetting angle", is a measurement used to determine how well a surface repels a liquid. To measure hydrophobicity, a small drop of water is used. The measurement is determined by the angle formed between the material's surface and a line drawn at the edge of the water drop where it meets the glass. See the graphic below of water on an untreated surface. DFI’s protective coatings produce contact angles ranging from 90-degrees to 110-degrees, depending on the coating quality. (See What is the difference between all of DFI’s protective coating products?)

15. Are DFI protective coatings colorless?

YES. All DFI protective coatings are optically clear and are guaranteed NOT to discolor, chip, crack, haze or peel off since the chemical bond created is permanent and integral to the substrate at nanoscale levels.

16. Where are DFI’s products manufactured?

DFI manufactures most of its products at our production facility in California, United States.

17. What is the warranty on the Diamon-Fusion coating?

Diamon-Fusion® treated surfaces are guaranteed to remain more water repellent than untreated glass for the lifetime of the glass as long as basic manufacturer maintenance recommendations are followed and no harsh or abrasive cleaners are used. DFl's patented nanocoating chemically bonds to the glass and creates a patented, protective nanofilm that when properly applied by an authorized reseller, is guaranteed not to discolor, chip, crack, haze or peel for the lifetime of the glass. Please see the complete Diamon-Fusion Warranty for important conditions and restrictions.
