Problem
Frequent cleaning is required to maintain the appearance and hygiene of surfaces like glass and ceramic due to the adhesion of dirt, grime, and stains. This is especially problematic in residential and automotive applications, where ease of maintenance is highly valued.
Solution
spotLESS Materials develops and markets ultra-repellent surface coatings that prevent the adhesion of dirt, grime, and stains. The coatings utilize a proprietary, PhD-developed technology to create an ultra-smooth barrier on glass and ceramic materials. This barrier reduces the need for frequent cleaning and simplifies maintenance in both home and automotive settings. The liquid-entrenched smooth surface (LESS) coating is applied in two steps: the first spray grows molecules that look like little hairs, with a diameter of about 1,000,000 times thinner than a human's, and the second spray acts as a lubricant.
Target Audience
The primary customers are homeowners and automotive enthusiasts seeking to reduce cleaning frequency and simplify the maintenance of surfaces.
