Q1: What types of solvents is Solvaperm Orange R Color Paste compatible with?
A: Solvaperm Orange R Color Paste is formulated for use in polar and moderately polar organic solvent systems, including esters, ketones, alcohols, and glycol ethers. It is not recommended for strongly acidic or highly water-rich formulations without prior compatibility testing.
Q2: Is this color paste suitable for food-contact printing inks?
A: Solvaperm Orange R Color Paste is designed for industrial and packaging applications where regulatory compliance is required. While it is free from certain heavy metals and meets common industry expectations for low-extractables, formal food-contact approval must be verified case-by-case based on final ink formulation, substrate, and applicable regional regulations.
Q3: How should the paste be dispersed in an ink or coating system?
A: For optimal dispersion, incorporate the paste under moderate shear using high-speed dispersers or three-roll mills. Pre-dilution with a portion of the carrier solvent may improve homogeneity. Avoid excessive heat or prolonged high-shear processing to preserve pigment integrity and rheological stability.
Q4: What is the typical dosage range when using this color paste in flexographic or gravure inks?
A: Dosage depends on the desired shade strength and substrate opacity, but it is typically used at low concentrations—generally ranging from 0.1% to 2% by weight of the total ink formulation. Optimization is recommended through small-scale trials under production-relevant conditions.
Q5: Does Solvaperm Orange R exhibit good lightfastness and thermal stability in cured ink films?
A: Yes—Solvaperm Orange R is engineered for enhanced lightfastness and resistance to thermal degradation during drying and curing processes typical in packaging printing. Performance may vary depending on film thickness, binder chemistry, and exposure conditions, so end-use validation is advised.
