In Paint and Coating:
Iron Oxide pigment is a very important and premium
colorant in industry, which is widely used in paint, coating,
paper, ink, plastics, rubber, machinery, construction and so
on in nearly every field of lives.
Basically, ferric oxide pigment includes red, yellow, black,
and brown colors are produced in manufactory, colors of
blue, green and orange etc. are compounded or mixed
from double or multiple those hues or color elements.
The well-content color is blended by suggestion or yourself.
We Kenal have been successful in this field with many years

The key roles of iron oxide listed:
Colorant
Rustproof
Filler agent
Polishing agent
Materials
Analytical reagent
catalyst
The main characters of ferric oxide pigment in practice:
strong coloring power
high covering strength
proper volume of oil absorption
non-toxic and environment friendly
various hues could be adjusted
insoluble in water or alkali or weak acid
durability and weather resistance
resistant to contaminated air
can absorb UV to protect the basic material from
degradation
Additionally, the color shine of iron oxide pigment is so pure
bright and clean that no cased embellishment by other
organic or inorganic color element, though the hue of some
of them shines bright or brilliant, the iron oxide has its
particular style like soft pleasing hue and majestic tonal,
widely used in house, public place, mansion and
construction painting indoor and outdoor.
The above advantages are not all contained by other
inorganic or organic pigments.
Iron oxide pigment is basically with four colors i.e. red, black,
brown and yellow. Green and blue is compounded
Classification and sorts of iron oxide pigment:
1. General iron oxide pigment
Red
Black
Brown
Yellow
2. Transparent iron oxide pigment
Particle size is under 5 µm, so it is also called Nano iron
oxide. it can help to raise and enhance weather
resistance of painting and coating, especially painting
for Auto with its transparence and UV absorption.
Metallic effect will come out while transparent iron
oxide blended with Aluminum pigment pearl powder
in Oil or Water based system. Not only Color effect
produced which is expensive organic pigment can only
be when mixed with organic pigment but also weather
resistance.
Red and Yellow in transparent iron oxide is popular
and widely applied.
3. Mica iron oxide pigment
Lamellar crystal, thermal endurance can be over 800
centigrade degree, non-toxic and rather stable.
Synthesis thickness of crystal is from 0.5 µm to 2 µm,,
smooth and undamaged, the transparent light is
beautiful blood red with metallic glossy reflected on the
surface of the crystal . The glossy is better if the particle
size of crystal is bigger than 50µm, mainly used as
antirust pigment and better metallic flash coating.
Peculiarly, major feature of coating of mica iron oxide:
i.
Good formed membrane
ii.
Adhesive force and connection performance
iii.
Air pollution resistant and UV radiation
iv.
Perfect durability
v.
Easy to painting into thick film
General iron oxide pigment:
Red: Fe2O3·α H2O
Iron oxide red pigment is most stable in ferric oxide system.
i.
Strong tinting and covering ability
ii.
Alkali and weak acid resistance
iii.
High purity and heat stability
iv.
Element connectivity
v.
Insoluble in water or solvent
vi.
UV absorbed and stabilization to light
vii.
Weather and light resistant
viii.
Hue saturation dense
Color does not change or fade at centigrade degree of 500,
even at 1200 will not change its chemical structure.
It can protect the basic material well when connected to
other application system for long time.
Modern ferric oxide material mostly is synthesis.
Compared to the natural iron oxide, synthesis iron oxide is
with good virtues in terms of:
Density is bigger
Particle size is smaller
Purity is higher
Covering power is prefer
Oil absorption is higher
Tinting is stronger
There might be three color hues in different particle sizes for
red iron oxide pigment powder:
Hue
Yellow
Red
Violet

Iron oxide pigment red powder widely used in antirust
coating as its physical feature to stop moisture in the air
infiltrating metal surface and to add compactness and
mechanical strength.
Application of iron oxide pigment red powder:
Construction
Color cement, color floor tile, color cement tile,
imitation of glazed tile, concrete block, color mortar,
color pitch, terrazzo, mosaic tile, Manu-marble and
coating for wall etc.
Colorant and protection in coating
Including water based coating for powder and
wall indoor and outdoor, not only oil based primer
and finish paint like epoxy, alcohol acid and amidogen
etc., but also paint for toy, decoration, furniture and
enamel paint etc.
Replace red lead in antirust to save non-ferrous metal
and money.
Colorant in plastics
Like colorant for rubber and thermoplastic &
thermosetting plastic.
High grade Polishing material for precise instrument
and optical glass etc.
Yellow:
FeOOH
Feature of iron oxide pigment yellow powder is widely used
in construction and second only to red in volume.
Except for the heat stability of iron oxide pigment yellow
powder is poor; other property is more or less with red.
It will change to red hue on condition that water losing
under heat of 135-177 centigrade degree, it turns into iron
oxide red powder if the temperature is over 270-300
centigrade degree.
So please do not used in coating which needs
high-temperature to dry.
Wally Pale tone, bright and brilliant gloss of yellow ochre
use widely and generally in construction.
Key merit of feature:
Tinting power
Light and alkali resistant
Durability
UV absorption
Brilliant and bright
Iron oxide pigment yellow is superior to yellow chrome in
terms of light and alkali resistance. Thus, iron oxide yellow
pigment is suggested in construction to replace expensive
and toxic yellow chrome. Beside, khaki and clay bank is
preferred in yellow in construction.
Transparent yellow iron oxide pigment is one of best
pigment.
Compounded iron oxide yellow pigment can produce
variety of color hues by special demand.
Good grinding
Strongly absorb visible light
UV radiation shielded
Protect basic material from degradation
Increase the life of service
Low cost
Iron oxide yellow pigment can be made into green when
mixed with phthalocyanine blue and into brown once
blended with iron oxide red and black.
Black Fe3O4
Strong tinting power
Saturated black light with blue and black gloss
Stable to air and light
Alkali and weak acid resistant
Easy to disperse, Specific gravity is larger than carbon
black which can prevent the floating color in system
Impermeability outstanding
Durability and protect base stable
Non-toxic
Best pigment as colorant of concrete in construction
Brown γ-Fe2O3
It is compounded by iron oxide pigment of black, red and
yellow.
Better tinting and covering power
Absorb almost all ultraviolet spectrum
It is mostly used as camouflage material by this
advantage which has similar even same infrared
reflectivity so that target will not be detected by
infrared camera in air.
Note:
Heat resistance and stability of Iron oxide pigment black,
brown or yellow is not good enough to red:
Red can stand at 200°C,
135°C for yellow
100°C for black
130°C for brown
Please notice this tip when applied in practice.
These colors of iron oxide pigment might turn into another
color or change the attributes if temperature is over the
limit.
Orange iron oxide pigment
It’s mixed by iron oxide pigment yellow and red.
Mainly and widely used in prefabricated concrete.
Other feature is similar with brown.
Green iron oxide pigment
One compound color of iron oxide pigment yellow and
phthalocyanine blue.
Stable chemical feature
Strong ability to absorb UV radiation
Light and air resistance
Toxic, please note.
Green iron oxide pigment performs well in cement to
replace green chrome.
Blue iron oxide pigment
Bright color
Strong tinting power
Acid and oil resistant, but no alkali resistance.
Poor covering power
hard texture
Iron oxide may bring early aging in polymer cause its
activity of some catalysis, please envelop the surface of iron
oxide pigment powder by aluminum oxide, silica oxide or
organ silicon to decrease its activity when put into use in
plastics.
Both Iron oxide pigment and phthalocyanine blue have
antioxygenation, so you have to control the volume used in
plastics.
The common proportion of used iron oxide pigment
powder compared to weight of cement is 4-8%, 5% is best
suggested. (roughly showed in following page)
Meanwhile, no content of compound of aluminum or zinc,
or the strength and set time of the concrete will be affected.
Do not make iron oxide pigment expose to sulfide to avoid
color changed or turn.
In a word, iron oxide pigment is most used in construction
and painting.
