Application of water-based shoe paint leveling agent
In the field of shoe material manufacturing, water-based shoe paint is gradually replacing traditional solvent-based
shoe paint due to its advantages such as environmental protection and low volatile organic compound (VOC) emissions.
However, water-based shoe paint also faces some challenges during use, such as poor leveling and many surface defects
of the paint film. In order to solve these problems, water-based shoe paint leveling agent came into being.
1. Definition and function of water-based shoe paint leveling agent
Water-based shoe paint leveling agent is a chemical additive specially used to improve the leveling performance of
water-based shoe paint. It can reduce the surface tension of the paint and make the paint spread more evenly on the surface
of the shoe material, thereby eliminating or reducing defects such as orange peel, pinholes, shrinkage holes, etc. on the surface
of the paint film, and improving the smoothness and flatness of the paint film.
2. Main components and types of water-based shoe paint leveling agent
The main components of water-based shoe paint leveling agent include silicone, polyurethane, acrylic resin, etc. These components
can effectively reduce the surface tension of the paint and improve the leveling of the paint film. According to the different chemical
structures, water-based shoe paint leveling agents can be divided into acrylic, silicone and fluorocarbon types.
Acrylic leveling agents: Acrylic leveling agents mainly improve leveling performance by reducing the surface tension of the paint.
They usually have good compatibility and stability and are suitable for various types of water-based shoe paints.
Silicone leveling agents: Silicone leveling agents can significantly reduce the surface tension of the paint and improve the wettability
and leveling of the paint film. At the same time, they also have excellent high temperature resistance and adhesion, and are suitable for
shoe manufacturing processes that require high temperature baking.
Fluorocarbon leveling agents: Fluorocarbon leveling agents are additives that are highly effective in reducing surface tension, but the price
is relatively high. They are usually used in occasions where the performance of the paint film is extremely high, such as high-end shoe
manufacturing.
3. Application methods and precautions of water-based shoe paint leveling agents
Application method:
Addition amount: The addition amount of water-based shoe paint leveling agents should be adjusted according to the specific paint and
shoe material types. Generally speaking, the addition amount is more appropriate between 0.1% and 0.5%.
Adding time: The leveling agent can be added during the preparation of the paint or before construction. When added during the preparation
process, ensure that the leveling agent and the paint are fully mixed and evenly mixed.
Construction conditions: During construction, appropriate temperature and humidity conditions should be maintained to ensure that the paint can
dry and level normally.
Precautions:
Avoid excessive addition: Excessive addition of leveling agent may cause defects such as shrinkage cavities and fish eyes in the paint film.
Pay attention to compatibility: When selecting a leveling agent, ensure that it has good compatibility with the paint used.
Construction environment: During construction, the construction environment should be kept clean and dry to avoid pollution from dust and impurities.
4. Application effects and advantages of water-based shoe paint leveling agent
Improve the quality of the paint film: The use of water-based shoe paint leveling agent can significantly improve the smoothness and flatness of the
paint film, reduce defects such as orange peel and pinholes, and make the surface of the shoe material more beautiful.
Enhance the adhesion of the paint film: Some components in the leveling agent can react chemically with the shoe base material and the paint to form
a strong chemical bond, thereby improving the adhesion and durability of the paint film.
Reduce production costs: By using leveling agents, the rework and repair costs caused by paint film defects can be reduced, thereby reducing production
costs.
Environmental protection and safety: Water-based shoe paint leveling agents are usually made of environmentally friendly and non-toxic raw materials,
which will not cause harm to the human body and the environment. Compared with solvent-based leveling agents, they have lower VOC emissions and
better environmental performance.
5. Conclusion
Water-based shoe paint leveling agents have broad application prospects in the field of shoe material manufacturing. By reducing the surface tension of
the paint and improving the leveling and smoothness of the paint film, they can significantly improve the appearance quality and durability of the shoe
material. At the same time, water-based shoe paint leveling agents also have the advantages of environmental protection and safety, and reducing
production costs. Therefore, the rational use of water-based shoe paint leveling agents in the shoe material manufacturing process is of great
significance for improving product quality, reducing production costs and protecting the environment.
