Durable, High Transmission, Easy Clean Hard Coat for Glass
Developed specifically for Electronic Touch panel applications but equally applicable to any glass surface that is repeatedly touched, cleaned, and exposed to the elements. The thin coating does not hinder the functionality of the glass surface in any way and is completely unnoticeable, while also increasing longevity of the coated surface. TPD400 leaves the surface smooth, having excellent finger sliding properties.
Scratch-Resistant, Clear, Easy-to-Clean Coating
TPD400 is a one-component solution forming a highly transparent and clear, thin coating over a glass substrate such as touch screens. Based on nanotechnology, the optimized composition of the organic-inorganic matrix provides easy to clean properties with excellent scratch resistance. TPD400 is compatible with various application processes such as spraying and rolling. TPD400 coating provides excellent cleanability, reducing the formation of stains and fingerprints, while also preventing scratching due to its hardness. The coating is highly durable to chemical and environmental exposure, including high humidity, salt corrosion, UV-light, and temperature changes, without degradation of performance. TPD400 is a great choice for glass surfaces that need abrasion resistance and easy cleanability. It also has a high temperature stability, keeping its properties even in changing temperatures.

The TPD coatings have the benefit of eliminating the cosmetic distraction of fingerprints and other contamination from skin contact. The extremely thin coatings of less than 100 nm enhance clarity and transparency of the original glass due to their tuned refractive indexes. Optitune’s patented monophasic siloxane nanomaterials result in a matrix, where the chemical functionality is controlled on molecular level yielding a homogeneous and durable coating structure, resulting in a glass surface that lasts longer against scratches and the elements and is easy to clean.
How to Apply
Typical application process for TPD is a spray coating followed by thermal curing which binds the coat into the substrate material. The viscosity of the solution can be adjusted to fulfill the ready-to-spray conditions of an automated industrial coating line. TPD is also available in formulations designed for other coating processes such as slot, dip, and roller coating techniques. Before applying, filtering the coating solution is recommended. Both IR and convection oven heating are suitable for thermal curing.Data Sheet - TPD400
