T/SHXCL 000002-2019 Nano-sized narrow molecular weight distribution acrylic resin with water-based coating
Basic Information
Scope
Scope: This standard specifies the technical requirements, test methods, inspection rules, and marking, packaging, transportation, and storage for nano-sized, water-based, narrow molecular weight distribution acrylate resins. This standard applies to nano-sized, water-based, narrow molecular weight distribution acrylate resins, which are used as raw materials in various application fields such as metal paints, wood coatings, coatings, inks, leather, and textiles. Main technical contents: - Appearance: There should be no particles or foreign matter, and the color should be even. - Color: A semi-transparent blue-gray liquid. - Average particle size (D50)/nm: 40–75. - pH value: 6–8. - Viscosity (25°C)/mPa·s: 10–30. - Solid content/%: 40–50. - Glass transition temperature/°C: 10–60. - Minimum film-forming temperature/°C: 2–20. - Molecular weight distribution index (PDI): ≤1.05. - Volatile organic compound content (VOCs content)/mg/kg: ND. - Dry time/min: ≤15. - Storage stability: 48h, no abnormalities. Note 1: ND = Not detected (detection limit 0.2mg/kg).
