AAU Hydrophobic Nano ED Paint Coating System Container Paint

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.

1. we recommend NOCS coating systems as below:

1. Chemical resistance:

NOCS performs 2 times better than waterborne paint in Alkali resistance and Acid resistance.

2. Durableness:

NOCS performs 2 times better than waterborne paint in weathering resistance.

3. Conventional performance:

NOCS performs better than waterborne paint in hardness, impact resistance and stain resistance.

(Note: In stain resistance and stone chip resistance, the higher the level is, the smaller the number it uses.)

4. 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.

1. 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.

1. Comparison tests between NOCS with zinc rich shop primer and NOCS without zinc rich shop primer have been implemented as below table.

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.

1. 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.

Detail:

1. Exterior: 90um (Shop primer 10um +NOCS 80um), No paint in circle

After 360 hours’ CASS test, there is no rust, no blistering, no cracking and no flaking on the surface except the circle, and the corrosion area did not expand wider than original circle.

1. 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.
