Cleanliness test against ink with NAPA leather using pens and edding, an example showing the effectiveness of e.g. Mr. Kepeki Leather

Corrosion test: Copper Accelerated Acetic Acid-Salt Spray Test 

(CASS Test - ASTM-B368)

   Uncoated Al   

100%  corroded

2.5 µm coated Al 

ca. 1 % corroded  

Win!!

   G2F metal corrosion test - coated Mr. Kepeki series on Aluminum -5052

 

   Based on ASTM-B368, 1 day CASS = 8 years real environment!

Test parameters

1. NaCl 5%

2. Humidity 95-98%

3. pH: 3.1~3.3

4. Temperature: 49°C

5. Air pressure: 0.07~0.17Mpa

5. Hardness Test                                                                

​

Mr. Kepeki Black

Mr. Kepeki White

                    Pencil test machine

Test specification

1. 1 kgw counterweight

2. 8H and 9H pencils

3. Speed: 1 time/ sec

The coated Al surface can’t be damaged by a 8H pencil

The coated Al-surface can be damaged eventually* by a 9H pencil

*Mr. Kepeki Black and Mr. Kepeki White themselves have hardness of 9H in principle. However, if coating was improperly performed, the hardness of the coated material may not really reach 9H e.g. inhomogeneous or too thin coating.

6. Anti-Bacterial Growth Test                                                              

 

 

​Mr. Kepeki Anti-Bacterial

 

A:

Initial CFU/ cm2 on uncoated sample

(ca. 0.62-2.5 E4)

B:

24 hr incubation after inoculation on uncoated samples

C:

24 hr incubation after inoculation on coated samples

Mr. Kepeki Anti-Bacterial successfully supressed bacterial growth on the coated surface!
