Painting Procedures
for Amphenol Antenna Solutions’ Antennas
SURFACE PREPARATION
For antennas with a fiberglass radome, solvents should be avoided. Remove any dirt, oil or
grease with a mild detergent and water. Scuff sand the antenna surface with 180 grit sandpaper
to remove any gloss. Soften the edges around the cracked paint. After sanding, wipe the surface
with a clean dry rag to remove all grit. For antennas with a textured polystyrene radome, scuff
sanding is not required. Clean the antenna with a mild detergent and water. Dry the surface
with a clean dry rag. Mask off the antenna connectors to protect from primer and paint.
PRIMER APPLICATION
Use a non-metallic primer. The recommended primer is Sherwin Williams DTMBondinR Primer
#B66A50. The primer may be applied by BRUSH, ROLLER, CONVENTIONAL or AIRLESS SPRAY. For
brush application, use a Nylon or Polyester bristle. For roller application, use a 3/8” Woven Nap
with Phenolic Core. For airless spray, use 2400 psi pressure min., .017”-.019” tip, 60 mesh filter and
1/4”-3/8” hose. For conventional spray, use Binks 62 gun, 66 Fluid Nozzle, 63 PB Air Nozzle, 60 psi
atomization pressure and 25 psi fluid pressure or equivalent equipment. The Primer may be
reduced using water up to 1 pint per gallon as necessary. Apply the primer to a thickness of
4.5-12.0 Wet mils / 2.0-5.0 Dry mils. Clean-up of Primer can be done with soap and water. Drying
times are shown below, but are temperature, humidity and film thickness dependent. (Times are
at 50% RH @ 8 mils wet / 3.5 mils dry thickness)

TOP COAT APPLICATION
Use a non-metallic paint. The recommended top coat (paint) is Sherwin Williams DTMAcrylic
CoatinR #B66 Wi 00 - Series. The top coat may be applided by BRUSH, ROLLER, CONVENTIONAL
or AIRLESS SPRAY. For airless spray, use 1500 psi pressure, .017”-.021” tip, 60 mesh filter and 1/4”
I.D. hose. For conventional spray, use Binks 18 gun, 66 Fluid Nozzle, 63 PB Air Nozzle, 50 psi atomization pressure and 15-20 psi fluid pressure or equivalent equipment. The Paint may be reduced
using water up to 1 pint per gallon for conventional spray. For brush, roller or airless spray, use
paint full-body. Clean-up of Paint can be done with soap and water. Drying times are shown
below, but are temperature, humidity and film thickness dependent. (Times are at 50% RH @ 8
mils wet thickness)
