How It Works

Glass is a naturally porous surface that contains thousands of microscopic peaks and valleys. Our coating works by chemically bonding to the surface, creating a smooth, ultra-thin barrier that seals the glass from harmful contaminants.

What It Does

Once applied to any glass or silica-based surface, the invisible coating repels water, grime, and contaminants from sticking. As a result, the surface becomes easier to clean, helps prevent stains, and looks cleaner for longer.

Why Choose DFI

For over 25 years, DFI has been developing protective coatings and restoration products for the glass industry. Our range of products have been used on prestigious landmarks worldwide and trusted by leading manufacturers in over 35 countries.

How our glass coating technology works

At a microscopic level, glass is extremely porous. As a result, minerals from hard water, soap scum, and other contaminants can easily penetrate the surface, causing unwanted stains. DFI’s protective coatings chemically bond to the glass, creating an ultra-thin barrier that seals the surface and provides a wide array of benefits.
