Frequently Asked Questions

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.

DFI’s Protective coatings are just like a top of the line sports cars. But just like a sports car you have to take care of your investment. When maintained properly they can last a lifetime. We recommend BASIC CLEAN.

BASIC CLEAN is highly concentrated biodegradable cleaning system for windows, mirrors and shower doors. BASIC CLEAN provides excellent slip and increased wetting but will not cause bleeding or allow squeegee chatter. There is no need for additional wetting agents.

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.

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 in 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.

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.

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.

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.

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 repellant 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.

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.

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.

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.

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?)

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.

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