Paints & Coatings

Feb 12, 2026

Effect pigments in paints and coatings serve a broader range of applications than any other end-use industry — from automotive refinish basecoats and industrial machinery finishes to architectural interior feature walls, epoxy decorative floors, and powder coatings on consumer goods. In each context, pearl, metallic, and color-shift effects must survive not only the application process but also the service environment: UV exposure, abrasion, humidity, and chemical contact. Two significant trends are reshaping pigment selection in this industry: the continued shift toward water-based and high-solids formulations under VOC regulation pressure, and growing demand for color-differentiated coatings in architectural and industrial decorative markets. Kolortek's coatings range covers standard pearl and metallic through chameleon and holographic effects, with grades compatible across solvent-based, water-based, UV-cure, and powder coating systems.

Kolortek's Solutions for Paints & Coatings

Application Scenario	Recommended Product / Series	Key Reason for Recommendation
Architectural interior decorative paint — pearl and shimmer	KT 100 Silver White Series	Chemically inert across water-based and solvent-based acrylic vehicles; multiple particle sizes (5–500 µm) for satin through coarse sparkle; stable through standard paint manufacturing and shelf life
Architectural feature wall — iridescent color effect	KT 200 Iridescent Series	Interference color visible in dried paint film; requires dark tinted or dark base coat for maximum color expression; medium grades (10–60 µm) suitable for roller application at acceptable orientation variation
Architectural / industrial decorative — warm metallic tones	KT 500 Metal Luster Series	Iron oxide-coated mica; warm bronze and copper tones; non-conductive; stable in water-based and solvent-based systems; no water-reactivity risk unlike aluminum
Industrial and architectural — vivid color with shimmer	KT Intense Chroma Series	Higher color saturation than standard interference pearlescents; relevant for coatings where vivid hue alongside pearl luster is the design specification
Premium decorative and custom automotive — chameleon color shift	KT 9000 Magic Chameleon Series / Chromashift Pigments	Angle-dependent color travel in dried coating film; requires black or dark base for maximum effect; used in custom automotive refinish, premium furniture coatings, and specialty architectural applications
Custom automotive and decorative — holographic rainbow	KT Holographic Pigments / XiallicSparks Pigments	Full-spectrum rainbow diffraction (holographic) and coarse-sparkle metallic effect (XiallicSparks); used in custom automotive, decorative architectural accent coatings, and specialty finishes
Solvent-based metallic coating — high-reflectivity silver	Kolortek Aluminum Pigment (leafing or non-leafing)	Leafing grades orient at film surface for mirror metallic appearance; non-leafing for distributed metallic effect through film depth; confirm passivated grade for any water-based system
Interior decorative paint — glow, fluorescent, or thermochromic novelty effect	Kolortek Glow in Dark / FDS Fluorescent / Thermochromic Pigments	Suitable for interior decorative architectural coatings and specialty applications; not positioned for automotive coatings due to UV and thermal exposure requirements of that application
Epoxy decorative flooring — metallic and pearl	KT 500 Metal Luster / KT 100 Silver White (coarse grades)	Chemical resistance of iron oxide and TiO₂-coated mica stable in alkaline epoxy cure environment; coarse grades (40–200 µm) produce visible metallic texture effect in cured floor

Particle Size Selection for Paints & Coatings

Visual Target	Particle Size Range	Why
Smooth satin / silk finish (thin film, spray-applied)	5–25 µm	Fine grades produce diffuse, even shimmer in thin paint films (20–50 µm dry film thickness); suitable for spray-applied automotive and industrial finishes
Standard decorative pearl (architectural interior)	10–60 µm	Most versatile range for decorative architectural and furniture coatings; balances visible shimmer with acceptable behavior across roller and brush application
Strong sparkle (architectural feature, epoxy floor)	20–100 µm	Individual platelet reflections visible in dried film; coarser grades require adequate film thickness to accommodate the platelet — unsuitable for very thin-film applications
Coarse metallic texture (epoxy floor, decorative industrial)	40–200 µm	Produces visible individual flake texture in thick-film applications; not suitable for spray application through standard spray equipment without testing nozzle compatibility
Holographic / XiallicSparks sparkle effect	Grade-specific — confirm with TDS	Holographic and metallic sparkle grades have specific particle size ranges designed for the diffraction or sparkle effect — refer to grade TDS for application-compatible size range

Substrate Selection for Paints & Coatings

Requirement	Natural Mica	Synthetic Mica	Borosilicate	Other
Water-based system compatibility	Good — chemically inert, no water reactivity	Good — chemically inert	Good — glass substrate, inert	Aluminum: requires passivated grade for aqueous systems
Thermal stability (powder coating, baking enamel)	Stable to 800°C	Stable to 800°C	Stable — confirm upper limit for specific grade	Iron oxide (KT 500): stable; Aluminum: stable in typical baking enamel ranges
Electrical conductivity	Non-conductive	Non-conductive	Non-conductive	Aluminum: electrically conductive — not suitable for coatings on electrical/electronic components
Color-shift capability	Not applicable	Not applicable	Not applicable	KT 9000 / Chromashift: angle-dependent color travel
Luster intensity	Good	Higher than natural mica	Highest sparkle per unit area	Aluminum: highest mirror reflectivity; Holographic: rainbow diffraction
Cost sensitivity	Lower — suitable for volume architectural applications	Higher than natural mica	Higher than mica	Specialty effects vary

Application Examples

Architectural Feature Wall Paint — Iridescent Pearl Product used: KT 200 Iridescent Series, 10–60 µm grade Effect achieved: A visible iridescent color shimmer distributed across the dried wall paint film, producing a color-play effect that changes subtly under different room lighting angles — warm directional light produces stronger color expression than diffuse ambient light. Formulation note: The iridescent effect requires a dark or tinted base coat for maximum color visibility — over a white-primed wall, the interference color appears weak. Recommend a mid-to-dark grey or tinted base, or use the paint over a dark primer. Pigment loading of 3–8% in a water-based acrylic dispersion is a typical starting range; adjust to achieve the desired intensity without affecting application viscosity. Low-shear mixing during manufacture preserves platelet integrity.

Custom Automotive Refinish — Chameleon Basecoat Product used: KT 9000 Magic Chameleon Series, medium grade Effect achieved: A color-shift basecoat that displays different hues at different viewing angles — the degree of color travel and the specific hue range depend on the grade selected. The effect is most pronounced under direct sunlight or strong directional light. Formulation note: Apply over a black sealer coat — the chameleon color shift is not visible over a silver or light grey primer. Disperse with low-shear agitation; high-shear mixing degrades platelet geometry and reduces color travel. Apply by spray at standard automotive basecoat film build. Topcoat with a standard automotive clearcoat at the specified film thickness to protect the effect layer.

Industrial Machinery Coating — Non-Leafing Aluminum Metallic Product used: Kolortek Aluminum Pigment (non-leafing grade), solvent-based system Effect achieved: A silver metallic appearance distributed through the dried paint film depth — non-leafing orientation produces a more durable metallic finish than leafing grades in abraded service environments, at the cost of reduced mirror reflectivity. Formulation note: Use in solvent-based alkyd or acrylic systems. Do not use standard unpassivated aluminum grades in water-based formulations — hydrogen generation risk. Apply by spray for consistent film thickness and metallic appearance uniformity. Non-leafing grades in roller or brush application produce less consistent metallic orientation than spray; evaluate before specifying for multi-method application.

Epoxy Decorative Floor Coating — Metal Luster Effect Product used: KT 500 Metal Luster Series, 40–150 µm grade Effect achieved: A warm bronze or copper metallic texture effect in the cured epoxy floor surface — individual metallic platelets visible in the cured film producing a distinct metallic character rather than a smooth uniform appearance. Formulation note: Incorporate the pigment into the epoxy resin component by gentle stirring before mixing with the hardener. Confirm pigment compatibility with the specific epoxy system's pH during cure — iron oxide mica is stable in alkaline epoxy cure conditions. Apply by roller or squeegee at the minimum film thickness required to fully accommodate the pigment particle size; coarse grades protruding through the film surface can affect floor durability and cleanability.

Contact Kolortek

Effect pigment selection for paints and coatings depends on the coating system (water-based, solvent-based, powder, UV-cure), the application method, the substrate or base coat color, the service environment, and the visual effect specification. Requirements differ significantly between a spray-applied automotive basecoat and a roller-applied architectural interior paint using the same pigment type.
