* On tanks and other large structures previously coated with
contrasting primer or intermediate coats, uniform appearance may
require two coats of Amercoat 450E. Use only a light colour primer
or intermediate coat when only one finish coat of Amercoat 450E in
a light colour is specified.
** Volume solids is measured in accordance with ISO 3233. Slight
variations 3% may occur due to colour and testing variances.
*** Brush or roller application may require additional coats to
achieve required dry film thickness.

Amercoat 450E
Surface Preparation
Amercoat 450E must be applied over a suitable
primer or intermediate coating. The surface of the
previous coatings must be dry and free of grease, oil,
dust, salts and other foreign matter immediately
before application.
Application Equipment
The following equipment is listed as a guide and
suitable equipment from other manufacturers may be
used. Adjustments of pressure and change of tip size
may be needed to obtain the proper spray
characteristics.
Application Data
Substrates ............................. Steel, concrete, aluminium,
galvanizing or aged coatings all of
which have been suitably prepared
and primed.
Surface preparation................ Refer to the typical systems table
for specific primer or intermediate
coatings recommended.
Application method................. Airless or conventional spray,
brush or roller.

Amercoat 450E
Application Procedure
Amercoat 450E is packaged in the proper mixing
proportions of resin and cure which must be mixed
together before use.
1. Flush equipment with recommended cleaner before use.
2. Stir both resin and cure to a uniform consistency with a
power mixer.
3. Add cure to resin, and continue stirring for 5 minutes.
NOTE: since the potlife is limited and shortened by high
temperatures, do not mix more material than will be used
within the potlife at the specified temperature.
4. For spray application, thin only as needed for workability
with no more than 10 vol % of recommended thinner. For
application at temperatures below 10C (50F), more
thinner may be required to ensure proper atomizing.
NOTE: For brushing and rolling, normally no thinning is
required.
5. Apply a wet coat in even, parallel passes. Overlap each
pass 50% to avoid bare areas, pinholes or holidays.
6. Double coat all welds, rough spots, sharp edges and
corners, rivets, bolts, etc.
7. Application at 83 m (3.3 mil) wet film thickness will
normally provide 50 m (2 mils) dry film.
8. Check thickness of dry coating with a non-destructive dry
film thickness gauge, such as Mikrotest or Elcometer. If
less than specified thickness, apply additional material as
needed.
9. Small damaged or bare areas and random pinholes or
holidays can be touched up by brush. Repair larger areas
by spray.
10. In confined areas ventilate with clean air during
application and drying until all solvents are removed.
Temperature and humidity of ventilating air must be such
that moisture condensation will not form on surface.
11. Clean all equipment with recommended cleaner
immediately after use or at least at the end of each
working day or shift. When left in spray equipment,
Amercoat 450E will cure and cause clogging.
