Scratch-Resistant, Clear, Easy-to-Clean Coating
TPD400 is a one-component solution forming highly transparent and clear, thin coating over a glass substrate. 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. TPD400 coating provides excellent cleanability, reducing the formation of stains, scratches, and fingerprints. Coating is highly durable to chemical and environmental exposure, including high humidity, salt corrosion, UV-light, and temperature changes, without degradation of performance.
• Construction glass
• Display Glass
• Stovetop and oven glass
• Very high clarity and transparency
• High temperature stability
• Very good easy-to-clean properties and smudge removability, very smooth finger sliding properties
• Extremely high abrasion resistance and environmental durability
• >9H Hardness
• Can be combined with an AR coating to further improve optics
The TPD coatings have benefit of eliminating the cosmetic distraction of fingerprints and other contamination from skin contact. Thin coatings 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.
How to Apply
Typical application process for TPD is spray coating followed by thermal curing. The viscosity of the solution can be adjusted to fulfill the ready-to-spray conditions of the 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 is recommended. Both IR and convection oven heating are suitable for thermal curing.
