What is the principle of using a silicone coated plastic product brush treatment agent?

The principle of brushing treatment agents for silicone wrapped plastic products involves multiple fields such as materials science, chemical engineering, and surface treatment technology, and is a complex and precise industrial operation. The processing agent plays a crucial role in the bonding process between silicone and plastic, as it not only significantly improves the bonding strength but also optimizes the overall performance of the product.

Firstly, we need to understand the characteristics of silicone and plastic materials. Silicone, with its excellent properties such as high temperature resistance, oxidation resistance, and corrosion resistance, has a wide range of applications in fields such as electronics, medicine, and aviation. Plastic, on the other hand, has become an ideal material for manufacturing various components and products due to its good plasticity and processability.


The emergence of silicone coated plastic products with brush treatment agents is precisely to solve this problem. The main components of the processing agent include coupling agents, silane coupling agents, fluorine compounds, and polyhydroxy substances. These components are processed through specific ratios and processes to form a special chemical agent that can activate the surface activity of silica gel.

In the manufacturing process of silicone wrapped plastic products, the working principle of the treatment agent is mainly reflected in the following aspects:
1、 Surface activation

The active ingredients in the treatment agent can undergo chemical reactions with functional groups such as hydroxyl and carboxyl groups on the surface of silica gel, forming chemical bonds. This type of bonding not only enhances the binding force between the treatment agent and the surface of silicone, but also significantly improves the activity of the silicone surface. The activated silicone surface can better contact plastic materials, forming a tighter and more stable bonding interface.
2、 Improving adhesion

The treatment agent greatly enhances the adhesion of the silicone surface by activating it. This improvement is not only reflected in the bonding strength between silicone and plastic, but also in the bonding performance between silicone and other difficult to stick materials. Therefore, the use of processing agents in the manufacturing process of silicone encapsulated plastic products can greatly improve the bonding quality and service life of the products.
3、 Optimize product performance

In addition to improving adhesive strength, the treatment agent can also optimize the overall performance of silicone encapsulated plastic products. For example, certain components in the treatment agent can improve the wear resistance, weather resistance, and stain resistance of the silicone surface, making the product more stable and reliable during use. The processing agent may contain components that can react chemically with silicone and plastic, forming stronger chemical bonds.
4、 Environmental protection and safety

With the continuous improvement of environmental awareness, the safety requirements for industrial materials are also increasing. As a chemical preparation, the environmental and safety considerations of silicone coated plastic product brush treatment agents are also very important. Modern treatment agents typically use environmentally friendly and non-toxic formulas and production processes to ensure that they do not pose a threat to human health and the environment during use. At the same time, the use of treatment agents also needs to strictly comply with relevant safety operating standards to ensure the smooth progress of the production process.
5、 The formation of a protective layer to prevent aging and pollution

Some special formulations of processing liquids can prevent aging caused by environmental factors and form a protective film on the surface of silicone rubber to resist the influence of external pollution.
6、 Compatibility adjustment

A specific type of brushing solution can help improve compatibility and interoperability between two different materials. In some applications, such as electronic device sealing or medical product manufacturing, these special brush coatings can also provide additional properties such as conductivity and anti-static.
In summary, the principle of using a silicone coated plastic product brush treatment agent is to achieve stable and reliable adhesion between silicone and plastic by activating the surface activity of silicone, improving adhesion, optimizing product performance, and ensuring environmental safety.
