Several months ago, a new customer named Jason – an owner of a Maaco Collision Repair & Auto Painting business in Minnesota – called Photodon. His problem? He had been purchasing a protective cover for his Satorius TopMix2 Paint Terminal that
A) didn't fit (it was like a bag around the machine);
B) was expensive (around $100.00); and
C) had to be replaced monthly because the plastic would get damaged when the paint had to be cleaned off it.
The TopMix touch screen is connected to a scale and mixer. When the paint is mixed, as you can imagine, it can splatter. In addition, the paint shop workers often touch the screen with gloves that have paint on them. This means that the very expensive touch screen needs to be protected.
Jason explained, "I use a paint thinner to clean the screen about once a week, and the protector I'm using gets damaged quickly. I'm spending a fortune on these protective covers. "I'm hoping you can help me."
Photodon's highly scratch-resistant oleophobic 9HO screen protective film is a rockstar in Photodon's film lineup. Not only is it one of the most scratch resistant films available on the market, it is extremely clear, with a glass-like finish. It's easy to clean, affordable and — unlike tempered glass — it's shatterproof.
But what exactly does 9H mean in terms of scratch resistance?
There are many ways testing labs will evaluate the hardness of a given material. One common way is to test a surface with minerals of varying degrees of hardness to determine if it will scratch a surface. Another way is to use pencils that are on a hardness scale that ranges from 2H to 9H. The higher the number, the harder the lead.
The most commonly used pencils are 2H on the hardness scale — not very hard. You may notice that if you use much pressure on a #2 pencil tip, the tip will break easily. Many artists will use 9H pencils — the hardest pencil grade available — so their pencils don't break as they draw.
Photodon's 9H Hardness Test:
One way Photodon's screen protectors were tested was by using pencil hardness methods as set forth by the highly reputable American Society for Testing and Materials (ASTM) International Standards. Photodon's 9HO film surface was evaluated for its ability to withstand scratches using these graded pencils.
