When using solvent red 24 for plastic dyeing, the following points should be noted:

1. Dosage of dye: Adjust the amount of dye according to the plastic substrate and the desired color depth.

2. Dispersion of dyes: Before mixing dyes and plastic resins, it is necessary to fully disperse the dyes to prevent particle aggregation and uneven dyeing.

3. Uniform mixing: Ensure that the dye and plastic resin are thoroughly mixed to avoid uneven dyeing or color deviation.

4. Baking and curing: Some plastics require baking or curing treatment after dyeing to improve the dye’s fixation rate and weather resistance in the plastic.

In summary, solvent red 24 has a wide range of applications in the dyeing of plastics and color masterbatch, providing bright and uniform colors for plastic products. During use, attention should be paid to the dispersion, uniform mixing, and baking curing of dyes to ensure the dyeing effect and product quality.
