D. APPLICATIONS
GENERAL:
P.V.37, a Dioxazine Pigment, imparts Bluish Red hue and is slightly more reddish shade than P.V.23 pigment. It has a slightly better overall performance compared to PV-23 and is particularly resistant to migration.
PLASTICS / POLYMERS
- * Poly Olefins -When PV37 is used for polyolefin coloring, the heat resistance of 1/3 Sd can reach 290 °C, but when dosage is decreased, its heat resistance drops sharply.
- * PE The light fastness can reach 8 grades in PE, and in reduction can reach 7~8 grades. It is suitable for general purpose polyolefin plastics, general engineering plastics.
- * PP / POLY ESTER / NYLON-6
- Pigment Violet 37 is suitable for pre-spinning of polypropylene, polyester and nylon 6 fibers spinning, the concentration should not be too low, otherwise, there will be a colour change
- * In Plastics P.V.37 has the advantage of being considerably more migration resistant than P.V.23
- * In Paints, P.V.37 exhibits a considerably more reddish shade and has slightly reduced tinctorial strength.
- * Inks – In NC Printing inks based on nitrocellulose and PU are unique in that it provides high tinctorial strength and excellent gloss.
- * In other oil-based printing inks for purposes such as offset printing, it is somewhat weaker than P.V.23, but exhibits high gloss and good flow behavior.
- * Its main field of application within the printing ink industry is in metal deco printing. Its Fastness properties in such applications equal those of P.V.23.
