DSP’s advanced PVD Titanium coating

DSP uses advanced Physical Vapor Deposition (PVD) coating technology based on cutting-edge high vacuum technology to produce elegant, beautiful durable colors and produces arc-ion plated colored stainless steel products. copper roofing manufacturer

This surface treatment process allows for wear-resistant coatings to be 10 times stronger than normal stainless steel products and lasts longer than any other coloring process known to date.

The DSP stainless steel products are characterized by their color and gloss which are semi-permanent and strong enough to withstand acid rain and contaminants. It has also greater resistance to fire and to chemicals than any other exterior finish materials.

Ahead-of-competition features of DSP’s PVD Titanium coating

ü  The Hardness of Thin Films

The hardness of the thin film of this product measured with the Micro Vickers tester is at least 10 times higher than that of stainless steel.

ü  Adhesion of Films

As a result of performing the peel test by scratching the product with a knife at an interval of 2 mm and putting cellophane tape on the surface, no film peeling was observed.

ü  Shock Resistance

As a result of visual assessment by observation after a 1-kg steel ball dropped on the product from the height of 50 cm by using the DuPont impact tester, there was no damage or discoloration.

ü  Scratch Hardness

As usual scratches start to appear from ion plating scratched at the speed of 150 mm/min by using the Clemens type scratch hardness tester. Ion plating has 3 times higher scratch hardness than chemical plating.

ü  Artificial Sweat Test

The artificial sweat liquid similar to human sweat (PH 4.5, JIS LO848) is prepared. The ion-plated frame is then submerged at room temperature for 8 hours. Afterward, it‘s removed and left to dry at room temperature for 16 hours. The table shows the results obtained when this sequence is repeated 7 times. No corrosion of ion plating from artificial sweat occurred on the metal plate. pvd coating colors

ü  Wear Resistance

As a result of applying a load of 500g on an eraser by using a SUGA rotational abrasion tester on the surface with a thickness of 0.5 microns for ion plating and wearing it down for 200 repetitive cycles, the color reaction of chemical compounds were exposed but ion-plated films were not peeled off.

ü  Wet Test

As a result of visually observing the change in the color of the ion-plated material after being left for 500 hours at the temperature of 50°C and the humidity of 98%, no problem was found.
