How to Choose Nylon Mesh for Paint Filter Paper...

“Same mesh count, different results.”  
One roll runs flawlessly; the next breaks, blots glue, and ruins a shift.  
Nine times out of ten, the problem is not the line—it’s the mesh you chose.
  
MAISHI has supplied PA6 nylon mesh for paint papers for 18 years. Here is the short version of what we have learned.
 
1. Look at aperture, not only mesh count  
Mesh count alone does not govern flow.  
• Standard weave: 29 % open area  
• MAISHI high-flow weave: 36 % open area  
Result: 12 % faster filtration under identical acrylic paint.  
Rule of thumb: target particle size × 1.4 = required aperture. Order by aperture, not by “165 mesh”.
 
2. PA6 is enough—if it is treated right  
Many buyers assume only PA66 survives epoxy, urethane or strong solvents.  
Our heat-set, anti-oxidant treated PA6 shrinks < 1.5 % at 150 °C / 30 min. Glue weight CV stays below 3 % after every restart.  
Check your actual oil-bath temperature before paying 10 % extra for PA66 you may not need.
 
3. Stock depth = lead time  
MAISHI keeps bulk PA6 rolls 200–300 m long in 125-200 micron aperture.  
Slit to any width, heat-sealed edges, packed and shipped the same day.  
No waiting, minimal trim waste.
