Resistant cooking plastic ink pigment selection and application

Ink temperature cooking is mainly refers to the heat resistance of the ink, Jimo layer under heat discoloration resistance level. Plastic ink heat in the cooking is mainly refer to packaging, sealing and heat resistance during compounding, mainly as heat resistance ink fading, color, graphic, etc. is not clear. Depends on the heat resistance of the ink pigments and binders, binders poor in heat resistance, heat will from white to brown, therefore, depends on the heat resistance of the light ink the link material, the heat resistance of the color inks depends on the pigment. This will be the red organic pigment ink for example, the heat resistance of the ink and the pigment selected for analysis discussed.PVC flame retardant
Heat experiments organic pigments; retort plastic ink by different resin materials and colorants link, auxiliary agents (such as fillers, wetting agents, viscosity reduction, etc.) composition. Organic pigment is insoluble in water and organic solvents, is highly dispersed particulate colorant, bright colors, high color strength, light resistance, weather resistance, heat resistance, solvent resistance, migration resistance and good dispersibility.PVC plasticizer
In this experiment, the choice of four types of red pigment of the plastic ink colorant retort test, because the red pigment is a pigment commonly used in printing inks, solvent-based inks in most types of organic red pigment; but in general the heat of red pigments points 4, colorful, even minor discoloration can also be distinguished.
