Coated, heavy-duty, monochrome, four-component waterborne polyurethane-based, cement and aggregate mortar layers with excellent abrasion, impact, chemical and other physical erosion resistance. It has a shallow textured aggregate surface, as well as mild slip resistance. They are available in thicknesses of up to 5-9 mm.
Pros:
Resistant to a wide range of organic and inorganic acids, bases, amines, salts and solvents. Chemical Resistance PropertiesThe coefficient of thermal expansion is similar to that of concrete, maintaining the same displacement as the substrate during normal thermal cycling, and is not prone to cracking.
and retains its physical properties over a temperature range of -40 C to 115 C.
The bond strength is greater than the tensile strength of the concrete (the concrete fails first).
No stains and no odor.
Toughness when subjected to impact deformation does not cause cracks or delamination.
Contains pure silicon aggregate structure with high wear resistance.
Cons:
The material cost is high, and the material cost makes the application scenario of the product in a niche and difficult to promote;
The requirements for the base layer are high, and the construction must be carried out on the ground above C25 without burning pulp and no hollowing, and the cost is high, because the loss caused by the construction of the base layer is not up to standard
There are many construction details, high construction costs, and the professional requirements of the construction team are higher
