For industries that rely on precise and durable coloration, understanding the technical specifications of pigments is paramount. NINGBO INNO PHARMCHEM CO.,LTD. provides a detailed look at Organic Pigment Blue 15:3, a widely used phthalocyanine blue pigment, highlighting its key technical properties that make it suitable for demanding industrial applications.

Organic Pigment Blue 15:3, identified by its CAS number 147-14-8, is recognized for its consistent quality and performance. As a 'Green Shade' blue, it offers a specific chromaticity that is highly sought after in various manufacturing processes. Its appearance as a fine blue powder is the starting point for its excellent dispersibility, a crucial factor for achieving uniform coloration in plastics, coatings, and inks.

One of the standout features is its impressive heat stability, often rated up to 230°C or higher. This high heat resistance is fundamental for its use in plastic processing, where materials undergo significant thermal stress during extrusion and molding. This property ensures that when you buy Organic Pigment Blue 15:3, you are investing in a pigment that will maintain its color integrity under challenging manufacturing conditions.

Lightfastness is another critical parameter. Organic Pigment Blue 15:3 typically achieves a rating of 7-8 on the standard 1-8 scale, indicating excellent resistance to fading when exposed to UV light. This makes it ideal for exterior applications, automotive coatings, and products intended for prolonged outdoor use, guaranteeing the longevity of the color.

The pigment's interaction with oils and solvents is also well-defined. Its oil absorption range, commonly between 32-42 g/100g, influences its rheological behavior in different media. Resistance to various solvents, including ethanol, toluene, and MEK (methyl ethyl ketone), further confirms its robustness and suitability for diverse formulations, particularly in inks and coatings where solvent compatibility is key.

In terms of chemical stability, Organic Pigment Blue 15:3 demonstrates good resistance to acids and alkalis, typically rating 4-5 in resistance tests. This chemical inertness ensures that the pigment does not react undesirably with other components in a formulation or degrade when exposed to mildly acidic or alkaline environments.

NINGBO INNO PHARMCHEM CO.,LTD. emphasizes that these detailed specifications—from pH and moisture content to resistance properties—underscore why Organic Pigment Blue 15:3 is a preferred choice for manufacturers prioritizing quality, durability, and consistent performance in their products. Its technical prowess makes it a reliable pigment for a wide array of sophisticated applications.
