Expansion of color space for architectural coatings

In the North American market, coatings have been color
at
(
POS)
50 years. The
POS
system was introduced by the predecessor of
Colortrend
Co., Ltd., which introduced a range
12
colorants. This
12
standard colorants that lay the foundation for the concept of color matching and color systems used in machines worldwide. It is not uncommon for other color systems to have
9
or even
10,
colorants, and in Europe some systems contain up to
16
colorants. Although there are many quantities of colorants available, the final color space or color range is determined by the color (or brightness) of the organic colorants in the series. This color space contains colorants such as organic yellow, medium yellow, organic red, magentia, indistinct blue, and indistinct green, while brightness
/
darkness is determined by black and white.
the emergence of new technologies, colorant research has benefited from a large selection of pigments, resulting in greater color space coverage. In addition, the diversity of pigments has led to the expansion of color space, and some new pigments provide better outdoor durability and better opacity. As an added benefit, these new colorants are available to meet environmental requirements with a system of zero
VOC
and alkyl phenol polyoxyethylene ether
(APE)
.
the United
Colortrend
Co., Ltd. has developed

Zero

colorants, available in over
24,
colors. Table

list of existing colorants, as well as their respective can codes, color index numbers, and product descriptions.
to see the dramatic impact of these new colorants on color range expansion, we chose high-performance colorants to compare
standard colorants. For this comparison, the calculated absorption values
'K'
and scattering values
'S'
are used to predict the total color range that can theoretically be used now. In this visual comparison of colors, the colors are evenly separated at certain intervals to indicate the range of colors obtained. In figures

and
1b
, a

diagram is given, in which the brightness value

as shown in Figures
1a
and
1b
, there is a larger color expansion in the yellow
-
red and blue
-
red signal areas, while the blue
-
green and yellow
-
green signal areas have only smaller color expansions. The system's total high coloring intensity is a much-needed advantage that increases opacity, especially for neutral base colors. In short, brighter, brighter and darker colors are available.
Colortrend
module
has so many different colorants that customer combinations or "modules" have been prepared according to customer requirements, so that
10
,
12
, and even
16
can be used. Modules can be divided into several categories, such as Standard, High Performance, and High Performance Above.
standard module
In the standard
Colortrend 808
module, colorants are color equivalent to
12
colorants in the
Colortrend 888
system (containing glycol), but simply transition from traditional to environmentally friendly colorants. In Figure
2
, the colorants in the module are represented by their respective can codes.

Façade
modules
Usually, inorance colorants
(KX, I, F, C
and
L)
are used in situations where very durable pigments are required and are the limit of color space. The color space has been expanded with the addition of inorganic colorants
(BVE)
, chromium oxide green
(CGE)
and cobalt blue
(CBE)
to the
Façade
module. Figure

contains the entire series of colorants for this module.

The color space is
further expanded by adding cobalt green
(IGE)
, inorganic orange
(IOE)
and group blue
(UBE
colorants, as well as other inorganic colorants mentioned in the
Façade
module. The entire series of colorants for this module is shown in figure

.
façade
colorants are suitable for paints containing silicates and silicones. For applications that require excellent durability,
Façade
module provides a large number of tones, greatly expanding the color range.
comparison at the same dosage
To demonstrate that a wider color range is now available, add the same amount of colorants to the base paint containing three levels of titanium dioxide, see Figures
7a
,
7b
and
7c
. The colorant modules for comparison are standard modules and high-performance
plus
modules. The colors available in light paint are determined by the base paint used, the amount of colorant added, and the colorant itself.

paint, expanding the amount of color available when using a specific base paint by adding a high-intensity colorant. In figures
7a
to
7c
, the colorants of high-performance yellow
(AGF)
, high-performance orange
(ORE)
are used instead of standard yellow
(AXX
and medium yellow
(T)
colorants, respectively, to improve the color resistance of these colors. There is no mid-yellow color
series,
only a small part of the color space. However, the color space expands significantly
the
of organic oranges, or "ORE". High-intensity red
(REE)
, blue
(EXE)
, green
(DXE)
, and magenta
(QME)
colorants may allow for a higher degree of opacity of the base paint to make colors, because the amount of color added to the same color is greatly reduced. For some colors, this results in a higher overall opacity that better meets consumer demand
,
because of the reduction in the number of lanes that need to be painted. This color range is impressive for the extended color space that can be found in each base paint.
in neutral base paint, you get a deeper, stronger, more beating color, while increasing opacity because the total amount of pigment in the colorant is higher. High-intensity colorants help increase opacity, and the color range is expanded by
-
orange, purple, turquoise, fresher magenta, and brighter reds from new pigments used in colorants.

the use of colorants is best expressed in the color system that consumers can visually feel.
