TECHNICAL SUPPORT
01	Dusting powder blowing out of hopper.
02	No air - percolating thru powder surface.
03	Rat holing - air blowing large jet holes through powder surface.
04	Stratification powder separating into layers of fine and coarse particles.
05	Plugged from impact fusion hard build-up.
06	Insufficient powder feed.
07	Poor charging inadequate powder build or wrap on part.
08	Poor penetration - powder will not coat Faraday Cage areas (holes, grooves, channels inside corners and recesses).
09	Back charging powder layers are repelled from part in spots..
10	Powder picks up a random charge through powder or in fluid path.Reverse charging usually through reclaim system.
11	Powder feed spurting or slugging - interrupted powder feed.
12	Poor spray pattern - not a symmetrical powder cloud (not applicable when using special deflectors for desired effect.).
13	Contamination in reclaim powder..
14	Spray booth dusting- inadequate air flow through spray booth..
15	Poor impact resistance/ poor flexibility..
16	Poor adhesion..
17	Poor corrosion resistance.
18	Poor chemical resistance.
19	Poor pencil hardness/ poor abrasion resistance..
20	Poor surface flow - too much orange peel.
21	Gloss too low for high gloss powder..
22	Gloss too high for a low gloss type powder..
23	Contamination in powder..
24	Inconsistent film thickness.
25	Off colour.
26	Pin holing and gassing through coating surface.
27	Pull-away or tearing coating film shrinks leaving bear substrate.
28	Poor fluidising properties in the powder hopper.
29	Blockage in venturi and hoses.
30	Blockage in the gun.
31	Insufficient wrap-around .
32	Poor penetration into corners, flanges, slots, etc..
33	Poor adherence of powder to parts, powder falls from part easily.
34	Dust, precured or other coarse material.
35	Matting of powder surface.
36	Orange- peel .
37	Cratering.
38	Pin holing.
