Environmental Friendly Waterborne Industrial Color Paste - Non-Toxic Pigments for Industrial Use

‌Technical Superiority of Modern Aqueous Color Pastes‌

‌1. Ultra-High Coloring Efficiency‌

• ‌Pigment load optimization‌:
  • Achieves 95–98% pigment strength vs. conventional pastes (ISO 787-24/ISO 6504-3), enabling 15–30% dosage reduction.
  • Nano-dispersed particles (D90 <1μm) maximize light scattering (Kubelka-Munk theory).
• ‌Cost-saving metrics‌:
  • Reduces colorant consumption by 1.2–1.8 kg per ton of base paint for mid-tone shades.
  • 5% improvement in ΔE accuracy at 1/3 SD tinting levels (DIN 6175-2).

‌2. Precision Rheology Control‌

• ‌Newtonian flow behavior‌:
  • Brookfield viscosity: 800–1,200 cP @25°C (LVT spindle #3, 60 rpm).
  • Thixotropic index: 1.0–1.2 (ASTM D2196) ensures anti-settling stability.
• ‌Low-energy dispersion‌:
  • Achieves Hegman 7+ fineness with 30% reduced mixing energy (400–600 rpm paddle agitation).
  • Compatible with high-shear (Disperser) and low-shear (Planetary) systems.

‌3. Premium Pigment Selection‌

‌4. Comprehensive Color Space Coverage‌

• ‌CIELab gamut‌:
  • Covers 98% of NCS 1950 Atlas (ΔE<1.5 tolerance).
  • Special effect pastes: Metallic (L* 25–90), Pearlescent (Interference 400–700nm).
• ‌Smart tinting systems‌:
  • 8–12 base pastes achieve 99% color match accuracy (Datacolor 800 spectrophotometer).

‌Professional Application Protocol‌

‌1. Pre-Use Compatibility Verification‌

• ‌Stepwise testing procedure‌:
  1. Prepare 500g base paint sample (ISO 15528 sampling).
  2. Add 2% color paste incrementally under 400rpm stirring.
  3. Check for:
     • Flocculation (Hegman gauge)
     • Viscosity shift (Stormer KU viscometer)
     • pH fluctuation (±0.5 tolerance)
• ‌Troubleshooting matrix‌:

  ‌Issue‌	‌Corrective Action‌
  Seediness	Increase dispersant (0.2–0.5% BYK-190)
  Viscosity drop	Add associative thickener (RM-8W, 0.1%)
  Color float	Adjust surfactant HLB (12–14 optimal)

‌2. Optimal Dispersion Methodology‌

• ‌Standard incorporation process‌:
  1. ‌Pre-dilution‌: Mix paste:water = 1:1 (vol) for carbon black; 1:0.5 for oxides.
  2. ‌Addition rate‌: ≤5% paste/min of total batch volume.
  3. ‌Post-tinting mix‌: 20min @30–40°C (jacketed vessel preferred).
• ‌Equipment guidelines‌:

  ‌Scale‌	‌Mixer Type‌	‌Tip Speed‌
  <500L	Cowles blade	8–12 m/s
  500–2,000L	Sawtooth impeller	6–8 m/s
  >2,000L	Helical ribbon	3–5 m/s

‌3. Storage & Handling Best Practices‌

• ‌Preservation protocol‌:
  • Temperature: 5–35°C (40°F–95°F).
  • Container: UV-block HDPE drums with nitrogen blanket.
  • Shelf life: 24 months (unopened), 6 months (opened).
• ‌Freeze-thaw stability‌:
  • Withstands 3 cycles (-10°C to 25°C) without rheology damage (ASTM D2243).

‌Critical Factors Impacting Color Paste Weather Resistance‌

‌1. Binder-Pigment Synergy‌

• ‌Emulsion selection criteria‌:

  ‌Resin Type‌	‌PVC Range‌	‌Weathering Performance‌
  Pure Acrylic	30–45%	10–15 years (Florida exposure)
  Styrene-Acrylic	35–50%	5–8 years
  Vinyl Acetate-Ethylene	40–55%	3–5 years

• ‌Minimum film requirements‌:

  • Exterior coatings: ≥30% emulsion content (ASTM D5324).
  • Critical UV zones: 35–40% resin for TiO₂ extension.

‌2. Pigment/Extender Optimization‌

• ‌Anatase TiO₂ prohibition‌:
  • Rutile grade mandatory (≥98% purity, CI77891).
  • Surface treatment: Alumina-silica-zirconia (ASZ) coating preferred.
• ‌Filler restrictions‌:

  ‌Material‌	‌Maximum Load‌	‌Rationale‌
  Calcium Carbonate	15%	Alkaline degradation risk
  Talc	10%	Water sensitivity increase
  Kaolin	20%	Chalking acceleration

‌3. Formulation Balancing Techniques‌

• ‌Deep shade optimization‌:
  • Reduce TiO₂ to 5–8% (vs. 18–25% in pastels).
  • Increase UV absorbers (2–3% Tinuvin® 1130).
• ‌Critical pigment parameters‌:

  ‌Color Depth‌	‌PVC‌	‌CPVC Adjustment‌
  Pastel (LRV >70)	35–45%	+5% vs. standard
  Mid-tone (LRV 30–70)	28–35%	±0%
  Deep shade (LRV <30)	20–28%	-8% to prevent mud cracking
