A light green opaque pigment can refer to various inorganic or organic compounds used in paints, plastics, inks, and other materials to impart a light green color with non-transparency. Here's a detailed overview of commonly used light green opaque pigments:
🔹 Common Light Green Opaque Pigments
1. Chromium Oxide Green (PG17)
Chemical Name: Chromium(III) oxide
Chemical Formula: Cr₂O₃
Color: Dull to medium green; lighter versions can be achieved with mixing
Opacity: High (very opaque)
Lightfastness: Excellent
Weather Resistance: Very good
Toxicity: Generally considered safe, but avoid inhaling dust
Uses:
Industrial coatings
Artist paints
Cement and construction materials
2. Cobalt Green (PG19)
Chemical Name: Cobalt(II) oxide with zinc oxide
Color: Light bluish-green or mint green
Opacity: Medium to high
Lightfastness: Excellent
Heat Resistance: High
Toxicity: Low to moderate (cobalt compounds may be hazardous if ingested or inhaled)
Uses:
High-temperature ceramics
Artist-grade oil and acrylic paints
3. Phthalo Green YS (PG36) or BS (PG7) with Titanium White
Base Pigment: Phthalocyanine Green
Light Green Version: PG36 mixed with titanium dioxide (PW6)
Opacity: Opaque when mixed with white
Lightfastness: Excellent
Stability: Chemically stable
Uses:
Printing inks
Coatings
Plastics
🧪 Characteristics to Consider
Property Description
Hue Soft mint, apple green, or pastel green
Opacity Typically enhanced with titanium dioxide
Binder Compatibility Acrylic, oil, alkyd, vinyl, etc.
Applications Art, industrial coatings, plastics, ceramics
🟢 Custom Formulations
A light green opaque pigment is often formulated rather than sourced as a single compound. A typical formulation might be:
Base Pigment: Phthalo Green (PG7 or PG36)
Opacifier: Titanium Dioxide (PW6)
Extenders (optional): Calcium carbonate, barium sulfate
This provides a vibrant light green with strong hiding power and durability.
