Additional applications: Selected plastics and masterbatch systems, subject to application testing
Automotive Refinish Coatings
Pigment Red 179 is recommended for evaluation in automotive refinish toners and color-matching systems that require a transparent bluish-red or deep maroon shade.
It can be used in the development or matching of:
- Deep-red automotive colors
- Metallic-red colors
- Pearlescent-red colors
- Maroon and wine-red colors
- Transparent red toners
- Multi-layer high-chroma red effects
Its transparency allows formulators to adjust color depth without completely hiding metallic or pearlescent effect pigments.
Final color matching should always be conducted against the target vehicle panel, approved color standard or vehicle color code.
OEM-Style Automotive Basecoats
The product can be evaluated in OEM-style automotive basecoat formulations requiring:
- High transparency
- Clean bluish-red undertone
- Strong color saturation
- Good dispersion
- Stable shade after baking
- Long-term color durability
- Compatibility with effect pigments
Suitability for a specific automotive OEM program must be verified through the customer’s complete approval and testing process.
Use in an automotive coating formulation does not automatically indicate approval by a vehicle manufacturer.
Metallic Automotive Coatings
The high transparency of PR179 allows aluminum flakes to remain visible through the colored coating layer. This makes the pigment suitable for developing deep metallic-red effects with enhanced optical depth.
Depending on the formulation, PR179 can be combined with:
- Fine aluminum flakes
- Medium or coarse aluminum flakes
- Colored aluminum pigments
- Transparent iron oxide pigments
- Other high-performance organic pigments
The final face color, flop color and sparkle effect depend on the effect pigment, orientation, pigment concentration and film thickness.
Pearlescent Automotive Coatings
PR179 can be evaluated with mica-based, synthetic mica or other pearlescent pigments for rich red effect coatings.
Possible color directions include:
- High-chroma pearlescent red
- Deep ruby red
- Bluish metallic red
- Maroon pearl
- Wine red
- Multi-layer transparent red
Compatibility and flocculation resistance should be tested in the complete coating system.
Multi-Layer Transparent Red Coating Systems
High-chroma automotive reds may use a basecoat, transparent colored layer and clearcoat to produce greater visual depth.
In these systems, PR179 may contribute:
- Transparent bluish-red coloration
- Increased depth in shaded areas
- High color saturation
- Controlled maroon undertone
- Improved interaction with metallic or pearlescent layers
The recommended pigment concentration and layer position must be determined through formulation testing.

FAQ
Is Perylene Pigment Red 179 suitable for automotive coatings?
Final compatibility and performance must be evaluated in the customer’s complete formulation.
Is PR179 suitable for metallic and pearlescent automotive colors?
Yes. Its high transparency allows metallic and pearlescent effect pigments to remain visible through the colored layer.
The final optical effect depends on dispersion, pigment concentration, effect-pigment type, orientation and film thickness.
Can PR179 be used in waterborne automotive coatings?
The product can be evaluated in selected waterborne systems with an appropriate resin, wetting agent and dispersant.
Compatibility, viscosity, flocculation resistance and storage stability must be confirmed in the actual formulation.
What is the heat resistance of Pigment Red 179?
The current specification indicates heat stability up to 200°C under specified test conditions.
For automotive coatings, customers should focus on the actual baking cycle rather than treating 200°C as an unconditional performance guarantee. Please provide the resin system, baking temperature and baking time for technical evaluation.
Can you match our current Pigment Red 179 grade?
Yes. You can provide your current pigment sample, approved drawdown, liquid color paste or sprayed panel.
We can evaluate shade, color strength, transparency and selected application properties under agreed test conditions.
Send us your current sample, target shade and application conditions for shade and performance evaluation.
