What is viscosity?
In material science and chemistry, viscosity refers to the amount of resistance of a substance against its internal movement and deformation. In other words, viscosity indicates the strength and chainability of the substance against the movement of its internal particles. Materials with high viscosity have more time to deform and move their particles, while materials with a lower amount deform more easily.
Viscosity can have a great effect on the mechanical, absorbent and psychological properties of products. Proper selection and careful control of various materials, including resins, can help produce products with quality and desirable properties. Since this property refers to the material’s resistance to movement and deformation, in various industries, including resin industries, careful selection and control for this property is very important.

How does viscosity in resin work?
Accurate selection and control for viscosity in resin can help produce quality products with desirable properties. Adding additives such as chemicals and fillers to change the viscosity may improve the performance and properties of the resin. For example, increasing the viscosity may increase the strength and hardness of the resin, while decreasing it may make the resin softer and more moldable. By carefully controlling this property in resins, products with desirable properties and optimal performance are produced.
Types of liquids in terms of viscosity
Liquids are divided into two main categories with high and low viscosity. Liquids with high viscosity usually have a specific, stiff appearance and move at a slower speed, while liquids with a lower viscosity have a softer, more plastic appearance and move at a higher speed. These characteristics indicate the resistance of liquids to their displacement and deformation. Viscosity is seen in liquid materials such as water, oil, gas and chemicals and plays an important role in the properties and performance of these materials. Since viscosity refers to the resistance of liquids to movement and displacement, precise control over this property can help improve the efficiency and performance of liquid materials.
Classification of liquids in terms of Newton’s study
Newton divided liquids into two categories based on viscosity: Newtonian and non-Newtonian liquids.
Newtonian fluids have constant viscosity. In these fluids, the shear stress is directly proportional to the rate of deformation. This ratio is known as shear force density. Examples of Newtonian fluids include water, motor oil, and gasoline.
Non-Newtonian fluids have variable viscosity. In these fluids, the shear stress is not proportional to the rate of deformation and may change as the flow rate changes. Examples of non-Newtonian fluids include blood, shampoo, paint, and ketchup.
This division is based on the behavior of fluids against flow and deformation and is important for the design of fluid transportation systems such as pipes and pumps.
Why do we measure viscosity in resin?
Viscosity in resin plays a very important role and its measurement can help to optimize production processes and final product quality.
– Processing control: Viscosity can have a direct effect on the resin processing process. For example, high viscosity resins may require more pressure to pump or transfer.
– Product quality: Viscosity can have a direct effect on the quality of the final product. For example, resins with the right viscosity can help produce products with better mechanical properties.
– Stability: Viscosity can indicate the stability of the resin. Sudden changes in it may indicate problems such as undesirable polymerization or changes in composition.
Therefore, accurate measurement can help improve production processes and quality of resin products.

Application of viscosity in resin
Finally, viscosity is one of the most important physical properties of resins, whose role is crucial in controlling production processes, final product quality, and resin stability. Viscosity can have a direct effect on the resin processing process. For example, high viscosity resins may require more pressure to pump or transfer. Also, viscosity can have a direct effect on the quality of the final product. Resins with suitable viscosity can help produce products with better mechanical properties. Finally, viscosity can indicate the stability of the resin. Sudden changes in viscosity may indicate problems such as undesirable polymerization or changes in composition.
