Details of Blue Opaque Pigment

Blue opaque pigments are used in a wide range of applications — from fine art to industrial coatings and plastics — where strong, saturated blue color and good opacity are required. Below is a detailed overview of blue opaque pigments:

 

🔹 Common Blue Opaque Pigments

1. Ultramarine Blue (Pigment Blue 29)

Chemical Composition: Sodium aluminum sulfosilicate

 

Color Index: PB29

 

Opacity: Semi-opaque to opaque

 

Lightfastness: Excellent

 

Heat Resistance: Very high (up to 350°C)

 

Toxicity: Non-toxic

 

Notes: Made historically from lapis lazuli, now synthesized; vibrant but can be slightly weak in tinting strength.

 

2. Phthalo Blue (Pigment Blue 15)

Chemical Composition: Copper phthalocyanine

 

Color Index: PB15:1 (green shade), PB15:3 (redder shade)

 

Opacity: Typically transparent, but can be made opaque by:

 

Milling with opacifiers like titanium dioxide

 

Using certain resin systems

 

Lightfastness: Excellent

 

Tinting Strength: Very strong

 

Toxicity: Generally non-toxic

 

Uses: Widely used in paints, inks, plastics

 

3. Cobalt Blue (Pigment Blue 28)

Chemical Composition: Cobalt(II) aluminate

 

Color Index: PB28

 

Opacity: Semi-opaque

 

Lightfastness: Excellent

 

Cost: Expensive

 

Toxicity: Low in finished form, but dust can be harmful

 

Notes: Stable in high-temperature applications like ceramics and glass

 

4. Cerulean Blue (Pigment Blue 35)

Chemical Composition: Cobalt stannate (cobalt-tin oxide)

 

Color Index: PB35

 

Opacity: Opaque to semi-opaque

 

Lightfastness: Excellent

 

Weather Resistance: Very good

 

Notes: Muted, grayish-blue with excellent durability

 

5. Titanium Blue (Modified Blue with TiO₂)

Made by: Combining blue pigment with Titanium Dioxide (TiO₂)

 

Opacity: Very high due to TiO₂

 

Applications: Automotive, architectural coatings

 

Notes: Custom blends to improve hiding power and achieve specific hues

 

🔍 Key Properties of Opaque Blue Pigments

Property Description

Opacity Ability to block light from passing through; important for coverage.

Lightfastness Resistance to fading under light exposure.

Weather Resistance Especially relevant for outdoor uses.

Chemical Stability Important in plastics, coatings, and industrial applications.

Tinting Strength How much a pigment can color another material when mixed.

 

🖼️ Applications

Artists' paints (oil, acrylic, watercolor)

 

Industrial coatings

 

Plastics and polymer coloration

 

Automotive finishes

 

Ceramics and glass enamels

 

Printing inks

 

⚠️ Safety Considerations

Most modern pigments are non-toxic when used properly.

 

Cobalt-based pigments can pose a hazard if inhaled as dust.

 

Always refer to Material Safety Data Sheets (MSDS) for specific pigment safety.
