Ink-specific resin

Ink-specific resin is a crucial core material in ink, which serves as a carrier for pigments and has a decisive impact on the performance of ink. When using ink-specific resin, the following aspects should be noted:

1. Compatibility between resin and solvent

Ink-specific resins usually need to be mixed with solvents to form a stable ink system. Therefore, when selecting a solvent, it is necessary to ensure good compatibility with the resin. If the solvent is incompatible with the resin, it may lead to ink layering, precipitation or gel, thus affecting the printing effect.

2. The amount of resin used

The amount of resin used has a significant impact on the performance of ink. Insufficient usage may lead to insufficient viscosity and poor adhesion of ink; Excessive use may make the ink too viscous, difficult to flow, and even affect the drying speed. Therefore, it is necessary to adjust the amount of resin reasonably according to specific printing requirements and substrate characteristics during use.

3. Printing process parameters

Printing process parameters such as printing speed, pressure, temperature, etc. can all affect the performance of ink. Therefore, when using ink-specific resins, it is necessary to pay attention to these process parameters to ensure that they match the performance of the ink. For example, in high-speed printing, it may be necessary to choose resins with faster drying speeds; In situations where high adhesion strength is required, it may be necessary to choose resins with excellent adhesion properties.

4. Storage conditions

Special attention should also be paid to ink-specific resins during storage. It should be stored in a dry, cool, ventilated place, away from direct sunlight and high temperature environment. If the storage conditions are improper, it may cause resin deterioration or performance degradation. Meanwhile, it is also necessary to pay attention to the shelf life of the resin and avoid using expired resin.

5. Safety and environmental friendliness

Ink-specific resins also need to pay attention to their safety and environmental friendliness during use. Some resins may be harmful to the human body or the environment, so corresponding protective measures need to be taken when using them, such as wearing masks, gloves, etc. At the same time, it is necessary to choose resins that meet environmental protection requirements to reduce pollution to the environment.
In summary, when using ink-specific resins, attention should be paid to the compatibility between the resin and solvent, the amount of resin used, printing process parameters, storage conditions, as well as safety and environmental protection. Only by considering these factors comprehensively can we ensure the stability of ink performance, good printing effect, and guarantee the safety of operators and environmental protection.
