- a hydrogen bond network will be formed between them and the viscosity can be increased despite the addition of organic solvents and dilution. is there.
- Such an acrylic vehicle having a viscosity increased by hydrogen bonding exhibits so-called thixotropic viscosity characteristics (thixotropic properties) in which the viscosity changes according to the strain rate by adding inorganic fine particles. This is thought to be because when the strain is applied to the system during viscosity measurement, the inorganic fine particles move through the hydrogen-bonded system, and the number of hydrogen bonds that are broken changes according to the moving speed.
- the thixotropy of an acrylic vehicle to which inorganic fine particles have been added depends on the viscosity of the acryl vehicle and the amount of inorganic fine particles to be added. When the acrylic vehicle viscosity is the same, the more thixotropic the added fine inorganic particles, the higher the thixotropy.

- the stringiness of the dispersion paste composition greatly depends on the viscosity of the acrylic vehicle and the content of the inorganic fine particles to be added, and the content of the inorganic fine particles is large and the specific gravity is high! Inorganic particle dispersion paste composition can not withstand gravity and breaks easily! On the contrary, the inorganic fine particle dispersion best composition with a low content of inorganic fine particles and low specific gravity is difficult to cut, so it is difficult to cut, so the talyl vehicle adheres to the back of the screen when screen printing is severe.
- the amount of inorganic fine particles added to the paste composition used for screen printing is usually not large due to production costs and other process limitations.
- the fine particle-dispersed paste composition may not be able to sufficiently eliminate thixotropic stringiness.
- the addition of an organic compound having 3 or more hydroxyl groups improves the thixotropy of the paste composition. If an attempt is made to increase the number of organic compounds having 3 or more hydroxyl groups, decomposability and storage stability become problems, and the amount of inorganic fine particles to be dispersed in the acrylic vehicle is determined according to screen printing conditions. Therefore, the inorganic fine particles may not be added to a level that can improve the stringiness of the inorganic fine particle-dispersed paste composition.
- the inorganic fine particle dispersed paste yarn and the composition of thread breakage can be created when the composition is stretched.
