Epoxy self-leveling, also known as epoxy self-flowing floor and epoxy ground, is made of epoxy resin as the main material, curing agent, diluents, solvents, dispersants, defoamers and some fillers and other mixed processing of epoxy floor coating, combined with a specific floor construction process, on-site ground decorative construction of a class of flooring. This process can be based on the unevenness of the ground downstream flow, the ground for automatic leveling, and rapid drying, after curing the ground will form a smooth, flat, seamless mirror effect surface layer. In addition, self-leveling also has moisture-proof, antibacterial, anti-corrosion, and other characteristics.
Main characteristics of epoxy self-leveling
Epoxy self-leveling has chemical properties such as water resistance, oil resistance, acid and alkali resistance, salt spray corrosion resistance, and physical properties such as abrasion resistance, stamping resistance and scrub resistance. And the surface is bright, flat, beautiful, no joints, easy to clean, easy maintenance, durable, can meet the needs of modern industry on the floor, in the flooring materials occupy an important position, is the ideal long-lasting flooring materials for modern industry, and has been widely used in medicine, automobile, electronics, food, electricity, chemical industry and other industrial floor decoration.
Epoxy self-leveling composition
Epoxy self-leveling includes two parts: concrete base and epoxy self-leveling floor coating.
Concrete grass-roots level: The concrete with strength level not less than C25 is poured and molded at one time, when the floor has the requirement of pressure resistance and impact resistance, the concrete grass-roots level can be processed by two-way reinforcing steel mesh.
Epoxy self-leveling floor coating: bottom coating, middle coating, putty layer, top coating.
The bottom coating is epoxy primer, using penetration and adhesion of epoxy primer, continuous and uniform coating film, no leakage, to enhance the adhesion of the grass-roots surface.
The middle coating is epoxy mortar layer, epoxy two-component add appropriate amount of 100 mesh quartz sand, enhance the smoothness of the coating surface and the strength of the coating.
Putty layer for epoxy putty layer, epoxy two-component add appropriate amount of putty powder, further leveling of the coating surface, to achieve a flat surface, smooth.
The top coating is coated with color paint, and the self-leveling epoxy top coating is evenly troweled.
Epoxy self-leveling construction precautions
Epoxy self-leveling floor coating is a kind of epoxy resin, it is widely used in building construction, is a kind of environmentally friendly and harmless paint. It can ensure that the ground after the construction of non-skinning, as well as the flatness of the grass-roots level and surface strength, but also to fill the ground base of the original cuts or cracks, to ensure that the surface effect of self-leveling and anti-cracking. At the same time, the product can also be high-pressure washing of the grass-roots level to ensure that the ground clean.
However, epoxy self-leveling floor coating in the use of the process there are some precautions that must be observed, otherwise it will cause some irreparable damage to the building construction.
- Construction temperature needs to be ≥5℃, if you want to construct in <5℃ need to choose special formula. Humidity is recommended for construction below 75%.
- Construction to ensure air circulation, modulation of the amount of use, not more than 30 minutes.
- Construction process to do a good job of maintenance, to avoid the intrusion of dust and debris, affecting the effect of paint.
- After the construction is completed, it needs to be maintained for at least 7 days before being put into use. During the maintenance period, especially cannot have water or all kinds of solution infiltration.
- It is strictly prohibited to mix with other paints.
- Must be strictly in accordance with the prescribed proportion of the addition of curing agent.
- Keep the surface of the coated material clean, and the water content of the coated material must be less than 7%.
- Keep the painting environment clean, it is strictly prohibited to construct in the environment with a lot of dust.
Epoxy self-leveling coating characteristics
Epoxy self-leveling coating is made of epoxy resin and special curing agent as main material, and is processed by adding various auxiliaries, pigments, and fillers through strict proportioning. It not only has excellent chemical properties such as water resistance, oil resistance and chemical corrosion resistance, but also has the advantages of good adhesion, high mechanical strength, low shrinkage of paint film after curing, and can be coated into a thick film at a time, so it is widely used in modern industrial flooring.
The coating film is tough, wear-resistant, good chemical resistance, non-toxic and non-flammable.
The surface is smooth and clean, with good decorative properties, and can meet the requirements of class 100 cleanliness level.
It has high adhesion, strong mechanical strength, chemical resistance, and good electrical properties.
