added to its NTP Yellow product portfolio with the introduction of NTP Yellow 10G155.
This new product brings the outstanding color, opacity, and durability that people have seen in NTP Yellow, but further expands the durable color envelope to new applications.
A wide range of pigment chemistries is available with different levels of opacity, durability, chromaticity, and economics. These four properties are often antagonistic to each other, forcing a compromise on two or more of these key properties. At the same time, historical pigments like lead chromate are facing increasing regulatory pressure and are being formulated out of products.
The yellow color space has a wide range of pigment options that have a balance of chromaticity, opacity and durability. The new NTP Yellow (PY227) brings bright chromatic color, high opacity, and excellent durability all at the same time. This has led a plastics engineer to call it "bullet-proof” colorant. To complement the NTP Yellow, improvements of the RTZ Orange (PY216) yield a true orange color unto itself.
Color matches that used to depend on blends of organic and inorganic pigments can now be matched with all inorganic pigments for the ultimate in durability and a true expansion of the durable color envelope.
The NTP Yellow and RTZ Orange are compatible with a wide range of polymers in coatings and plastics for use in a wide range of applications, such as:
Pre-painted coil and extrusion;
Laminates and co-extrusions;
Architectural and façade coatings
Shepherd Color’s newest addition to its NTP Yellow product portfolio, NTP Yellow 10G155, brings the outstanding color, opacity, and durability that people have seen in NTP Yellow, but in a color shade closer to red-shade bismuth vanadate (PY184) pigments. It has higher heat stability and excellent weathering properties. Other key features of Yellow 10G155 include inertness to acids, bases, solvent and UV, no chromium or lead in the formulation, halogen-free, and non-warping in polyolefins.
