UV Curable Wood Primer - Wood Primers - Green Light Coatings Application Tech Tips

 

1.  Apply the primer to a wet thickness between 0.75 mil to 1.25 mil (0.00075” ‐ 0.00125”; 18u ‐  32u) per coat.  When cured, this will permit excellent sanding without burnishing through to bare wood.  Therefore, if the primer is burnished or sanded to reveal bare wood, it is very possible that the prime coat was not thick enough.

2.  As a visual aid to correct wet primer thickness, when applied correctly, the primer will appear to provide a wet appearance over 90%+ of the surface area.  Some areas may appear to be slightly dry due to increase pore sizes and greater absorption of primer.  This is normal if maintained to a minimum of 10% or less.  There should not be any discernible pockets, dimples or fish‐eyes.

3.  If fish‐eyes or repel spots occur, check for contamination on the wood surface.  The GL Series coatings have been specifically designed to be tolerant of certain wood rosins/resins but may not coat well over machine or other types of oils and certain other contaminants.

4.  Do not be alarmed should some grain raise be observed.  Grain raise is common with long fiber wood species such as with oak surfaces.  The primer will “lock” any raised grain in place and permit excellent sanding properties to remove any evidence of raised grain. Primer applied to wood – grain raised and fibers are “locked” in place Primed surface sanded to provide highly smooth surface for finish topcoat. No secondary grain raise will occur with topcoat application. primer coat wood substrate

5.  It is recommended to sand the dry primed surface with 220 grit media.  This will provide the smoothness quality necessary for superior topcoat application.

6. UV cure is best facilitated by a combination of gallium doped mercury vapor and standard mercury vapor lamps to promote through cure and surface cure of the high pigment content of the UV curable primer.

7.  If difficulty is experienced in sanding the primer, due to poor dusting or it gums up in the sanding paper, the primer is probably not sufficiently cured.  UV lamps may not produce the same intensity as they age.  Always check for UV lamp intensity daily or at a minimum weekly, and replace when sufficiently low that productivity suffers.  Product showing difficulty in curing may be cured by slowing the conveyor or passing product through the UV curing section once more to promote full cure.
