Nano One Coating System paint
Nano One Coating System(NOCS in short) is a new generation
double-component coating system, using a new type of Alicyclic
Alkenamide Urea (AAU) as the film forming material, which is one
kind of nanometer-material and a controlled polymerization material
that could provide high cross-linked and hydrophobic coating for
most metallic material.
1)Surface performance
Due to the characteristics of nanometer material, the formed film
of NOCS is so dense and smooth that it is not easy to be
contaminated, and its glossiness is high.
2) It performs well in early water resistance test which will be
done when a box is off the production line, and there is no problem
for production in winter and rainy days as well, because it is fast
drying.
- we recommend NOCS coating systems as below:
| Zinc rich shop primer | NOCS | NOCS (top coating with color) | Total |
| Exterior system | 10um | 40um | 40um | 90um |
| Interior system | 10um | 60um | / | 70um |
- Chemical resistance:
NOCS performs 2 times better than waterborne paint in Alkali
resistance and Acid resistance.
| System | Items | Nano OCS | WBP | Test standards |
| Exterior | Water resistance | 500hr; Adhesion 5B, pencil hardness 2H | 500hr; Adhesion 5B, pencil hardness HB | After 500 hours, no blistering, no shedding, no discoloration; GB-T 1733 |

- Durableness:
NOCS performs 2 times better than waterborne paint in weathering
resistance.
| System | Items | Nano OCS | WBP | Test standards |
| Exterior | Artificial accelerated aging resistance | ≥2000hr; △Ecmc 1.1, lost light 9% | ≥1000hr; △Ecmc 2.7, lost light 15% | Filtered Xenon arc radiation, no cracking, no chalking, no foaming GB-T 1865 Method 1 |

GB-T 1771 |
| Hydrothermal resistance | ≥960hr; △Ecmc 1.5 | ≥480hr; △Ecmc 2.3 | No blistering rust and no cracking, allowing slight color change. GB-T1740 |

| Hydrothermal resistance | ≥960hr; | ≥480hr; △Ecmc 2.6 | No blistering rust and no cracking, allowing slight color change. GB-T1740 |
- Conventional performance:
NOCS performs better than waterborne paint in hardness, impact
resistance and stain resistance.
| System | Items | Nano OCS | WBP | Test standards |
| Exterior | Hardness | 2H | HB | GB-T 6739 |
| Impact resistance | Positive 10 points; Recoil 8 points | Positive 10 points; Recoil 4points | ASTM D2794 |
| Stone chip resistance | Level 0.5 (Damage area 0.2%) | Level 1.5 (Damage area 2.5%) | Method B DIN 55996-1 |
| Stain resistance | Level 1 | Level 3 | 7 cycles, GB-T 9870-2013 |
| Interior | Hardness | 2H | HB | GB-T 6739 |
| Impact resistance | Positive 10 points; Recoil 8 points | Positive 10 points; Recoil 4 points | ASTM D2794 |
| Wear resistance | 29mg | 87mg | CS-17,500G,1000hr; ASTM D4060 |
| Stain resistance | Level 1
| Level 3 | 7 cycles, GB-T 9870-2013 |
(Note: In stain resistance and stone chip resistance, the higher
the level is, the smaller the number it uses.)
- Film flexibility:
NOCS performs better than WBP in bending resistance and impact
resistance.
Its better performance in bending resistance and impact resistance
means that if friction or collision happened partly on the film
surface during the usage, yet there will be no crack.
(Note: The sample panels were taken randomly from actual production
line.
Left = NOCS (painted in blue color), Right = WBP (painted in white
color))
- CASS Test results of random sampling during production carried out
by SGS authority
Theoretically speaking, 1 hour of CASS (Copper-accelerated Acetic
Acid-Salt Spray) test equals 8 hours of NSS (Neutral Salt Spray)
test, several sample panels were taken randomly from actual
production lines and were sent to do CASS test to check its
anti-corrosion performance.
- Comparison tests between NOCS with zinc rich shop primer and NOCS
without zinc rich shop primer have been implemented as below table.
| Coating system | Test results |
| Exterior | 90um (Shop primer 10um + NOCS 80um) | CASS Test 360 hours (NSS Test 2880 hours ) |
| NOCS 90um, no shop primer |
| Interior | 70um (Shop primer 10um + NOCS 60um) | CASS Test 360 hours (NSS Test 2880 hours) |
| NOCS 70um, no shop primer |
The test results indicate that NOCS without zinc rich shop primer
performs almost the same as NOCS with zinc rich shop primer, and
NOCS performs better than waterborne paint, as it has passed 360
hours in CASS tests, which is equivalent to 2880 hours in NSS test,
while conventional waterborne paint only meets 1000 hours in NSS
test.

- In the simulation tests of partial damage during actual usage by
leaving a circle without paint intentionally on sample panels, NOCS
passed 360 hours’ CASS tests (equivalent to 2880 hours in NSS test)
as well. And there are no rough edges around the circle, no
blistering and no corrosion penetration after tests.

- In conclusion
HLS NOCS was a customized solution for heavy duty machinery, which
had been applied for several years. It is environmental-friendly as
it is solvent-free and can dry at room temperature. Nano-structure
of NOCS is polyfunctional and contains high gel after crosslinking,
which makes the film hydrophobic and wear resistant with some
scratching self-healing performance and perform very well in
chemical resistance (Alkali and Acid), temperature and hydrothermal
resistance. Its better performance than waterborne paint in film
hardness, impact resistance and corrosion resistance and its
material characteristics of good sheltering performance, high
glossiness, and good flexibility make us consider NOCS a
comprehensive better choice as one kind of alternative coating
solutions for container industry.
