What is the function of interface agent?
Interface agent is also called interface treatment agent. Interface agent, in essence, it is a kind of adhesive. Common interface agents are generally made of vinyl acetate-ethylene.
The interface agent has strong cohesive force, excellent water resistance and excellent aging resistance. Generally, it is used to deal with the wall surface, or the surface layer where different materials such as the ground meet. So it is also called interface agent.
The common functions of interface agents are generally the following four points.
① Principle of action.
The interface agent is used on the surface of the wall or the surface of the ground. In other words, the surface of the object is treated. The effect formed at this time is actually the effect of physical adsorption and coating. At the same time, physical and chemical effects can be realized. In this way, the physical and chemical properties of the surface of the material or the interior of the surface layer are improved through the physical and chemical effects of the material itself. In fact, to sum up, it is to solve the bonding performance of the material surface.
② Solve the problem of adhesion between old and new materials.
This is mainly for wall treatment in home decoration.
When the home is renovated, the original wall is decorated. In the later stage, it needs to be redecorated, and the original wall surface needs to be dealt with at this time. In order to solve the problem of adhesion between the old wall surface and the new decorative layer. The interface agent was applied. This is also a common role of interface agents in home improvement.
The most essential role of the interface agent is to play a link between the previous and the next. Consolidate bond issues between base and finish layers.
③ Solve the problem of insufficient adhesion of the surface layer.
This aspect is mainly for concrete walls.
For concrete walls. Because it is made by pouring concrete through supporting formwork. So its surface is very smooth. The adhesion of smooth concrete surfaces is very low.
Therefore, in order to increase the bonding force between the concrete surface and the decoration material. Generally, the interface agent can be applied on the surface of the wall. Increases the bond between materials.
④ Solve the problem of the strength of the wall surface material itself.
The common interface agents now generally have two-way permeability.
The effect that can be achieved is to achieve two-way permeation bonding. After brushing the wall surface of the interface agent, the permeability of the interface agent can be used. Bond some less strong materials together on the surface of the wall.
For example, the most common wall surface has slight sanding. After applying the interface agent, you will find that the surface strength of the wall is very high. It can effectively solve the problem of sanding on the surface of the wall.
⑤ Play a certain sealing effect on the surface of the wall.
Use the interface agent to seal the wall surface. In fact, the main purpose is to achieve the aging resistance of the wall surface. It can also improve the acid and alkali resistance and weather resistance of the wall.
In addition, although the interface agent can play a certain sealing effect. But there is still good permeability. Therefore, it can also avoid the mold and mildew of the wall caused by the damp of the wall.
Landcel produces HPMC for interface agents. Effectively improve the adhesion of the interface agent. Improve construction efficiency. Consult us and get free samples.
