The photoluminescent pigment developed by the company is made by
activating alkaline earth aluminate with rare earth elements. This
material is characterized by performances such as light absorption,
light storage and light radiation and can glow in darkness for 12
hours continuously after it has absorbed various visible lights for
10-20 minutes. Its luminance brightness and duration is at least 30 times of
traditional luminescent materials represented by ZnS:Cu, and can be
used repeatedly. The test results issued by National Institute of
Metrology (NIM) demonstrate that the product is nontoxic,
radioactive free, and has stable chemical performance. It can be made into various photoluminescent products, and have
been widely applied to fire prevention, place-name signs, household
electric appliances, clocks and watches, finery, garments,
craftworks and gifts, and so on. Characteristics of Photoluminescent Pigment: 1.Contains no toxin or radioactive element, harmless to humans and
the environment;
2. Has less restriction on excitation light source. As long as the
light intensity reaches 25LX, it can be used as an excitation light
source, and in general buildings the light intensity can get to
500LX and above. Therefore, sunlight, general lighting, surrounding
stray light can be used as excitation source.
3.Able to produce high-luminescence afterglow in the next 12hours
after 10-20 minutes of exposure under the light, which is 30 times
of that produced by traditional phosphor;
4.Possesses excellent physical and chemical properties, can be used
outdoors or in extreme environment, able to resist ultraviolet, and
maintains its performance basically after thousand hours of
exposure to 300W high-voltage mercury lamp. It demonstrates sound
ability in resisting chemical corrosion and can be applied in a
wider temperature range (-20 to 500℃).
5.Available in multiple photoluminescent colors including red,
yellow-green, blue-green, blue, and purple and appearance colors;
6.Long service life (> 15 years) and its characteristics (light
absorption, storage and radiation) can be infinitely reused;
7.Can be processed into products in different grain sizes (0.5 -
200 um) corresponding to different industrial requirements.
Photoluminescent Pigment Classification:
At present, we four categories of Photoluminescent pigments: MH
series, MH-W series, MS series, and MT series
1. MH series photoluminescent powders are alkaline earth aluminate
phosphor-based luminescent materials, which are available mainly in
light yellow, grayish white, and light grey. Their luminescent
colors mainly include yellow-green, blue-green, blue and purple.
2.MH-W photoluminescent pigments are manufactured with MH pigments
through encapsulated process, which can be directly used for
water-based paint or ink.
3.MS series are sulfide-based photoluminescent materials, which
usually is present in red or white and the luminescent colors
include red, orange and white.
4. MT photoluminescent pigment have to be specially processed. They
have bright appearance, usually in red, yellow, green, and purple.
Surely, the appearance and luminescent colors can be particularly
prepared to meet with customer’s specific requirements. Notes & notices during application:
1.Most photoluminescent pigments are soluble in water and
decomposed in acid solution, therefore they should not be used in
water soluble and acid systems. In case that these pigments have to
be used in water-based paint or ink, MHG-W series products are
recommended.
2.Photoluminescent powders in general grain sizes usually have
better luminescence. However, it is recommended to select the
photoluminescent pigment of proper granularity in accordance with
your specific manufacturing process. For example, MHG-4B is
suitable for road surface brushing and roll coating; MHG-4C is
proper for brushing, roll coating, spray coating, silk screen (120
meshes), etc; and MHG-4D is better for brushing, roll coating,
spray coating, silk screen (160 meshes), and injection processes.
3.As the photoluminescent pigment has heavier specific gravity, it
has to be particularly mixed until it is evenly blended.
4. It should be stored in ventilated and dry environment. Moisture
prevention is required. If the pigment can not be used up in one
application, it should be sealed during storage.
5.Metallic materials will give significant influence on its
luminescent performance; therefore, it should be ground by avoiding
metallic materials as practically as possible. Photoluminescent Pigment Packaging, Transportation, and Storage:
1. Packaging: The standard package of the product composes of inner
plastic bag (1 kilo/bag) and external plastic barrel (25
kilos/barrel). Packaging in other forms can be used to customer’s
specific requirements.
2.Transportation: Measures should be taken to prevent corrosion,
extrusion, sun and rain.
3. Storage: It should be stored in ventilated and dry environment.
Anti-moisture measures are particularly required. Above suggestions are only for reference. In case of any question,
