Structure Of Inoxta Tile

Inoxta Tile and its Stainless backer are 300 series Stainless Steel, which has excellent corrosion resistance. A final surface layer is applied to create color by the use of Physical Vapor Deposition (PVD) utilizing Titanium.

Features of Ti-Color Coating


Thin film hardness

The hardness of the product film itself was measured by the Vickers hardness test and was found to be about 10 times harder than stainless steel.

Adhesion of the coating

The strength of the adhesion was tested by creating a 2mm wide scratch with a knife and attempting to peel off layers of the coating with cellophane tape. There was no peeling of the film.

Impact Resistance

A 2.2-pound ball was dropped from a height of 20 inches onto the product using a DuPont impact tester. There were no abnormalities such as discoloration or visible damage.

Material Hardness (HV)
Ion Coating 2250
Stainless (304) 150 ~ 170

Abrasion resistance

Using a SUGA abrasion tester, 1.1 lbs (500g) pressure from an eraser was applied to .5 microns of ion plating. The applied pressure was repeated 200 times. The ion plating film was not peeled.

Scratch hardness

Load of cracking point, as seen below, was tested by scratching 6 inches per minute with a Kuremence Scratch Tester. The results showed the ion coating to be 3 times harder than a chemical coating for scratch resistance.

Material Scratch Hardness
Ion Coating 15.7 Newtons
Chemical Coating 4.9 Newtons

Artificial sweat test

The ion-coated frame was presoaked in an artificial sweat of PH 4.5, JISLO 848 for 8 hours and left at room temperature for 16 hours. Ion coating tested significantly better than brass.

Material Result
Ion Coating | Gold No Change
Brass Partial pitting corrosion found
Multiple locations of corrosion

Wet Corrosion

No damage or color change was found on ion coating with exposure to 122°F, 98% humidity for a duration of 500 hours.

What is NCC?

NCC is a hybrid technology using an organic and inorganic coating to reduce maintenance of Stainless Steel Tile with anti-smudge, anti-bacterial and improved surface hardness.

NCC is a hybrid technology using an organic and inorganic coating to reduce maintenance with anti-smudge, anti-bacterial and improved surface hardness. Test results demonstrate strong resistance to bacteria such as Colon Bacillus (”E Coli”) and Staphylococcus Aureus (“staff”).

Laboratory tests with live bacteria

Test results prove strong anti-bacterial activity
