Application
Mainly used for high-grade wood, natural and synthetic leather, printing ink, vacuum plating, the aluminum foil and other metal coloring, and can be used in household electric appliance, auto decoration, printing paste can, plastic coloring, etc.
What precautions should be taken when applying Solvent Red 122 in wood coatings?
Wood coating application requires strict control of solvent selection, resin compatibility, and drying process to avoid quality issues, as specified in industrial application guidelines:
- Precise solvent matching: Prioritize polar organic solvents like 1-methoxy-2-propanol and 2-ethoxyethanol to ensure complete dissolution and prevent precipitation. Control dye concentration at 0.5-5% of the coating mass to balance coloring effect and film performance.
- Mandatory compatibility test: Test compatibility with resins (nitrocellulose, polyurethane, etc.) in advance. Inferior resins may react with the dye's chromium complex structure, causing color deviation or fastness reduction.
- Strict drying control: Conventional grades should not exceed 160°C during drying; high-temperature resistant grades can reach up to 200°C but avoid prolonged high-temperature exposure to prevent darkening. Ensure good ventilation to volatilize residual solvents.
What are the application requirements for Solvent Red 122 in plastics and printing inks?
Different substrates have specific technical requirements, based on industrial practice and quality standards:
Plastic Coloring
- Grade matching: Choose appropriate grades according to processing temperature—use 250°C high-temperature grades for engineering plastics (PC, ABS) and 160-200°C conventional grades for general plastics (PP, PE).
- Mixing uniformity: Pre-mix the dye with plastic pellets (ratio 1:100) before extrusion to avoid color spots. Ensure migration resistance (grade ≥4) to prevent dye transfer between plastic parts.
- Environmental compliance: Ensure the product meets Q/ZYQ002-2023 standard requirements, with strictly limited harmful substances to adapt to green production trends.
Printing Inks
- Solvent system adaptation: For solvent-based inks, use aromatic hydrocarbons or esters as co-solvents to improve dye dispersion. For gravure inks, control viscosity at 15-25s (Zahn cup) to ensure printing fluency.
- Fastness guarantee: Conduct rubbing fastness (grade ≥4) and light fastness tests in advance, especially for packaging inks to meet long-term storage needs.
- Residue control: Ensure residual solvent content meets GB/T 8826-2003 standard to avoid odor or safety risks in food packaging applications.
