The problem of many fasteners is their use on wet surfaces, because water destroys all kinds of building materials. That is why manufacturers have started to come up with new ways of fastening materials that would be resistant to both humid environments and aggressive environments, etc.
Chemical anchor in the construction market exists not so long ago, but masters from various fields know about its advantages. And whether it can be used on wet surfaces, we will tell you in our article.
What is a chemical anchor?
A chemical anchor is a type of fastener that is made on the basis of synthetic resins and is characterized by high adhesion to a variety of surfaces, so that fastening becomes possible even in the most seemingly problematic building materials, like hollow bricks.
The chemical anchor is made on the basis of:
- Epoxy resin;
- polyester resin;
- vinyloester resin.
Chemical anchor is usually sold and stored in tubes or cartridges, with which it is applied to the surface. The mounting material consists of two components that are connected in the cartridge mixer when exiting it. Also, a chemical anchor can be in ampoules, but this type of packaging is used less often.
Which chemical anchor is suitable for use on wet surfaces?
Imported chemical anchor Teknobond 401 W is used for application on wet surfaces.
This material is made on the basis of synthetic epoxyacrylate resin and is characterized by such characteristics as moisture resistance, thixotropy and high drying rate.
Teknobond 401 W material is widely used in the construction of both small rooms with high humidity, for example, bathrooms, and in the construction of large structures, for example, bridges.
Naturally, this chemical anchor can be used not only on wet surfaces, but also on dry ones.
What are the technical characteristics of the chemical anchor for wet surfaces Teknobond 401 W?
In addition to resistance to a humid environment, among the technical characteristics of the Teknobond 401 W, it is necessary to highlight:
- resistance to various chemicals;
- preventing the development of reinforcement corrosion;
- Strength – more than 70 N/mm2;
- Adhesion – more than 3 N/mm2;
- Bending strength – more than 20 N/mm2.
