Pink Opaque Pigment Suppliers In Maharashtra

Pink opaque pigments are a category of colorants used in paints, coatings, plastics, cosmetics, and other materials to provide a solid, non-transparent pink color. Here's a detailed overview of the types, composition, uses, and properties:

🔍 Overview of Pink Opaque Pigments

Pink opaque pigments are created using various organic and inorganic compounds, designed to scatter light effectively, giving a solid, non-translucent appearance.

🎨 Common Types of Pink Opaque Pigments

1. Pigment Red 122 (Quinacridone Pink)

Chemical Class: Quinacridone

Color: Bright magenta-pink

Opacity: Moderate to high (often made more opaque with additives)

Properties:

High lightfastness (resistance to fading)

Excellent weather resistance

Common in artist paints and automotive finishes

2. Pigment Red 170 (Naphthol Red)

Chemical Class: Naphthol AS

Color: Slightly warmer pink-red

Opacity: Moderate to good

Properties:

Good tinting strength

Used in printing inks, plastics, and coatings

3. Titanium Dioxide Blended Pigments

Base Pigment: Titanium Dioxide (TiO₂) for opacity

Method: Mixed with organic pink dyes or pigments

Properties:

Very high opacity (TiO₂ scatters light strongly)

Soft pastel pinks to strong vivid shades

4. Pigment Red 81 (Rhodamine-based)

Chemical Class: Xanthene dye lake

Color: Bright neon-pink

Opacity: Moderate; often semi-opaque

Properties:

Brilliant color, less lightfast

Used in cosmetics and fluorescent inks

⚗️ Composition & Chemical Aspects

Inorganic pigments (e.g., TiO₂-based): High opacity, good stability

Organic pigments (e.g., Quinacridone, Naphthol): More vivid, but usually need help from opacifiers like TiO₂

Lakes and dyes: Derived from soluble dyes precipitated with metal salts to increase insolubility

🧪 Key Properties

Property Description

Opacity Depends on pigment type; enhanced with TiO₂

Lightfastness Excellent in quinacridone, moderate in naphthol

Oil Absorption Varies, higher in organic pigments

Toxicity Generally low; some cadmium-based pinks are restricted

Heat Stability Good in most modern pigments (e.g., used in plastics)

🖌️ Common Applications

Industry Usage

Paints Decorative coatings, artist paints

Plastics Masterbatch colorants

Cosmetics Lipsticks, blush, eyeshadow

Textiles Dyeing and printing

Printing Packaging, magazine inks

✅ Selection Tips

For high durability: Use quinacridone-based pigments (PR122)

For cost-effectiveness: Naphthol pinks (PR170) are widely available

For cosmetics: Use FDA-approved lake pigments like D&C Red No. 27

For high-opacity pinks: Combine with titanium dioxide
