What's the use of screen printing ink additives?
There are two components added to the ink: one is solvent, and the other is additive.The main solvents are slow drying, standard and quick drying. They are diluted and selected according to the printing requirements.Additives are divided into curing agent, waist cutting agent, shaving agent, leveling agent and so on.Curing agent: with increased color fastness, there is an increase of tensile, according to different requirements, choose different types of curing agent.Waist cutting agent: mainly to increase the viscosity of the ink used.Shaving agent: as the name suggests, is to solve the bubble problem occurs, the amount must be used by the proportion of ink manufacturers to use.Leveling agent: when the print surface flow is not good when used, the amount of ink manufacturers should also use the ratio.When there is a problem in the printing process, try to solve the problem through the printing adjustment. When there is no way, do not use various additives, which may change the characteristics of the ink.
A lot of ink information, there are a lot of ink and printing friends
Some are to reduce the depth of color, and some to reduce the viscosity of the ink
There are many kinds of additives, such as increasing the fastness of the ink, reducing the viscosity of the ink, diluting the ink, making the ink slow drying, and making the ink quick drying. Most of the ink plus additives need to use up within the prescribed time, if not used up, some will fail, lost the role of additives, and some will be cross-linked hard, and some will become thin, resulting in completely useless.
