Summary of Lab Tests on Typical Wearlon® Coatings

The following are the main advantages of Wearlon® coatings.

1. Non-Stick Properties
   20 gr/in of release on Johnson and Johnson waterproof tape with subsequent adhesion of 100%
    
2. Low Friction Coefficient
   Static coefficient (on cold rolled steel) -0.11
   Dynamic coefficient -0.07
    
3. Hard Surface
   Impact test (extrusion) better than 90 cmX11 gr of impact
    
4. Excellent Adhesion to Surfaces
   Pull-off test > 400 psi (better than cyano acrylate) on cold rolled steel
    
5. Low Wear - Abrasion Resistance
   Excellent abrasion resistance - 1 mil loss after 3000 cycles CS-17 wheel at 1000 gr load (Tabor test)
    
6. Water and Solvent Resistance
   Passed most tests on immersion, splash and fumes of major organic solvents; salts; inorganic and organic acids (except oxidizing acids); alkaline solutions and most oxidizing agents
    
7. Anti-Corrosion
   JPCL Test (accelerated) - 36 out of 40 max (better than epoxy) without any corrosion on coated surfaces
    
8. UV-Resistance
   No degradation, cracking, or blistering > 30 days at QUV
    
9. Low Chipping
   Very low chipping, less than 0.3%
    
10. Flexibility to Folding
    Excellent. Passed OT test without cracking or deformation of coat.
     
11. Temperature Resistance to Sudden Change
    Maintains release and flexibility after 500°F for 16 hours.
     
12. Hydrophobicity
    High contact angles with water > 90°
    Excellent spreading with organic solvents 0° for CH2I 2
    Low surface energies < 40 dynes/cm
     
13. Electric Conductivity
    Very low - 10-11 mohs/cm
     
14. Environmentally Friendly
    Very low VOC
