Film thickness changes anchoring and feel
Too little adhesive may not surround the lower part of the flock fiber. Too much adhesive can slow drying, change hand feel or create visible surface variation.
The useful range depends on substrate absorption, part geometry, flock length and the application method.
Open time belongs to the full process
Record the time between adhesive application and flocking, then record drying before cleaning or abrasion testing. Compare samples at the same process points.
If a part has recesses or a long handling route, include that delay in the trial instead of relying on a flat coupon prepared immediately.
