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
