In modern industrial and commercial architecture, epoxy flooring must do more than just provide an aesthetic finish; it must withstand extreme mechanical wear, chemical spills, and frequent high-pressure cleaning. Pigment Green 7 (Phthalocyanine Green, C.I. PG7), such as the Pigment Green SY-276/277 series from Senova Chem, is the premier choice for floor coatings due to its unmatched chemical stability. However, achieving a flawless surface in thick-film systems requires high-performance additives to overcome the dual challenges of pigment dispersion and air release.

1. Molecular Advantages of Pigment Green 7: Alkali Resistance and Inertness

Epoxy floor coatings are typically applied over concrete substrates, which are inherently alkaline. Many organic pigments suffer from color shifting or fading when in contact with such high pH levels.

• Chemical Stability: Pigment Green 7 is a highly chlorinated copper phthalocyanine structure, making it one of the most stable organic pigments available. During the production of Senova SY-276, rigorous crystal control ensures superior alkali resistance. Even on damp, high-alkali concrete interfaces, the pigment maintains its vibrant shade without degradation.
• High Opacity and Tinting Strength: Floor coatings require high hiding power to mask visual inconsistencies in the substrate. SY-276 is micro-milled to provide deep, uniform green tones at low dosage levels, significantly improving the efficiency and quality of the final application.

2. Eradicating “Craters”: RP-6068 High-Efficiency Defoaming

Epoxy floor paints are often solvent-free or high-solid systems with high viscosity, which makes it extremely difficult for air bubbles to escape naturally. Trapped air leads to “pinholes” or “craters,” which not only ruin the aesthetics but also create pathways for moisture and oils to penetrate and damage the substrate.

• Technical Specification: Based on the RK-Chem 2025 Technical Manual, we recommend RP-6068 (benchmarked against Elementis 6500).
• Core Mechanism: RP-6068 contains 95% active matter. This highly concentrated silicone-polyether mixture rapidly reduces the dynamic surface tension of the epoxy. In thick-film coatings, it forces micro-bubbles to coalesce and burst quickly, ensuring a mirror-like surface even in large-scale industrial projects. Its high compatibility prevents secondary defects like shrinkage or fish-eyes.

3. RD-9781: Solving Color Floating in High-Load Systems

Epoxy floor paints often contain high amounts of quartz sand and calcium carbonate fillers. When these heavy inorganic fillers coexist with organic pigments like Pigment Green 7, “color floating” (separation of pigment and filler) is a common failure.

• High-Performance Dispersion: RD-9781 is a 100% solid content high-molecular-weight polymeric dispersant.
• Anchoring Mechanism: It attaches to the surface of SY-276 particles through powerful chemical anchoring groups. By creating a robust steric hindrance barrier, RD-9781 prevents the organic pigment from separating from the inorganic fillers during the leveling phase. This ensures a consistent, uniform color across the entire floor, regardless of the application method.

4. Technical Synergy: The Senova-RK Formulation Strategy

To achieve peak performance, a systematic approach combining Senova pigments and RK-Chem additives is essential:

• Color Integrity: Pigment Green SY-276 provides the durable optical base.
• Surface Control: RP-6068 eliminates structural pinholes.
• System Stability: RD-9781 maximizes grinding efficiency and long-term storage stability.
