Zinc Rich Electrostatic spray Epoxy Primer Pure Epoxy Powder
Coating
FH-ZP is an epoxy-based smooth satin coating with a high level of
zinc, providing excellent corrosion protection while improving the
adhesion properties of powder topcoats resulting in superior
service life and film integrity.
It is not recommended for exterior use without a topcoat,typically
used for garden tools, industrial waste equipment,agricultural
machinery, pipeline coatings, electrical switch gear,cabinets and
cable ducting.
APPLICATION SCHEDULE
Applied by corona electrostatic spraying equipment
Curing schedule : For single coat application : 10 minutes at
200°C (object temperature). For two coat applications : 3 minutes
at 200 °C (object temperature), then cure top coat as per 10
minutes at 200°C
Optimal film thickness : 60 - 90 um POWDER AND COATING PROPERTIES
Specific gravity : 2.0 - 2.2
Film thickness (ISO 2178) : 60 - 90 µm
Flow out : Good Gloss (ISO 2813, 60º) : 50-60 %
Adhesion (ISO 2409) : GT= 0 Pencil hardness(ASTM D3363 ) : 2H
Direct and reverse impact (ASTM D2794) : >50kg.cm
Salt spray Resistance ( ASTM B117, 2000hrs) (Maximum undercutting
,2 mm ): No blistering
Chemical Resistance :Generally excellent resistance to dilute
acids, alkalis, oil and most solvents at normal temperatures.
APPLICATION SUGGESTION FH-ZP has a higher average specific gravity
than standard powder coatings, therefore box feeders and fluidizing
hoppers will need to be tested to ensure adequate mixing. It may
require increased air pressure or vibration levels than standard

Technology: Dry method and high-energy ball milling technology, multi-coated
layer processing;
Advantages: Better dispersion, longer salt fog time, slowly sedimentation in
the coating material
Application:
Daceomet/Geomet technology, Zinc-Cr Coating material,
Powder coating and painting for ships and warships, Automotive
parts, Vehicle, Iron tower and the like;
Chemical property and features:
In electro-chemistry: compared to the base metal Fe being
protected, the Zn will be changed into solution in electrolyte to
show the effectiveness, even the base metal being exposed because
of the damage of the coating layer;
Sealing and tightness: the corrosion of the zinc powder (ZnCO3 and
Zn(OH)2) deposits among the voids of the small zinc particles as
filling stuff of the pigment, the electro-insulation makes it show
the natures as sealing effectiveness;
Shielding natures: the lamellar powder shows parallel line in the
surface of the coating film, as well as overlap and cross each
other, which makes the water or corrosion medium difficult to be
permeated that shows the anti-corrosion effectiveness.
