Application
in Plastic Systems:
|
JZ
series has been successfully applied in HDPE, LDPE,
PP, and PS systems with minimum adjustment to the
processing conditions. In theory, it should be
also applicable in many other plastic systems, but
we suggest that the end-users perform thorough
test of their own to determine the suitability and
adjust the formulation and processing parameters
accordingly.
|
|
Lightfastness:
|
The
degree of colorfastness of JZ series fluorescent
pigments vary depending upon many factors such as
the specific properties and dimensions of plastic
systems, pigment loading, presence of a protective
overcoat or agent and the light source. It is
reported that an improvement of 10 to 30% in
exterior light stability results from the
incorporation of 0.5 to 1.0% of a benzotriazole or
benzophenone type UV screen. It is essential to
select an UV screen that is compatible with the
plastic in which it is to be incorporated.

approved standard by trained technicians upon
preparing plastic chips and placed in standard
light box containing UV and D65.

|
Storage:
|
Indefinite
shelf life under conditions that are cool, dry,
covered, away from direct sunlight and free of
airborne contaminates. Upon exposure to heat and
humidity, JZ pigment tends to form lumps that need
to be crashed prior to use.
|
Toxicity:
|
Tests
conducted through independent laboratories have
found JCOLOR® JZ-Series Fluorescent Pigments
to be "essentially non-toxic."
MSDS is available upon request. Good
industrial hygiene and handling methods are
essential in the use of all products whether or
not they are determined to be hazardous.
