Interfacial agents are also called interface treatments. Surfacer, by nature, is an adhesive. Interface agents, like the ones we commonly see, are generally made of vinyl acetate-vinyl acetate.
Surfacer has a strong adhesive force, excellent water resistance, excellent aging resistance. It is generally used to deal with the wall or the ground and other different materials such as the intersection of the surface layer. So it is also called interface agent.
And the common role of the interface agent is generally the following five points.

① Principle of action.

We use the interface agent to treat the surface of the wall or the surface of the floor, which makes the surface of the object. At this time, the role of the formation of the physical role of the adsorption and coating effect. At the same time, physical and chemical effects can be realized.
This is through the physical and chemical role of the material itself to improve the material surface or surface layer of the internal physical and chemical properties. In fact, to summarize is to solve the bonding properties of the material surface.

② Solve the problem of bonding between the old and new materials.

Here is mainly for home improvement in the wall treatment. Because of our home improvement, then the original walls are decorated, later we need to redecorate. Then we need to deal with the original walls.
At this time in order to solve the problem of adhesion between the old wall and the new decorative layer. It is painted with an interface agent, which is also a common role of the interface agent in home decoration.
In fact, the interface agent to summarize the words: its most essential role is to play a carrier, consolidate the adhesion between the grass-roots level and the decorative layer.

③ Solve the problem of insufficient adhesion of the surface layer.

Here is mainly for our concrete wall. As we all know, for the concrete wall, because it is made by supporting the formwork and pouring concrete. So its surface is very smooth. And the bond of the smooth concrete surface is very low. So in order to increase the bonding force between the concrete surface and the decoration materials. Generally you can come to paint interfacial agent on the wall surface to increase the bond between the materials.

④ Solve the problem of the strength of the wall surface material itself.

Like now we see the interface agent, generally have two-way permeability, can realize the role is to realize the two-way penetration bonding. So we painted the interface agent of the wall. You can use the permeability of the interface agent. The wall surface of some of the strength of the material is not too high bonded together.
For example, our most common wall surface has a slight sanding situation. After painting the interface agent, it will be found that the wall surface strength is very high. It can effectively solve the problem of sanding on the wall surface.

⑤ Seal the surface of the wall to a certain extent.

The main purpose of using interface agent to close the wall surface is to realize 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 role in closure. But there is also good permeability. So you can also avoid the return of wall moisture caused by wall mold and so on.
Landcel‘s cellulose ether-based products can be used as additives for interfacial agents. They can be used as additives for interfacial agents to improve the workability of interfacial agents and to enhance the effect of interfacial agents. Please feel free to contact us for free samples.
