Epoxy resin is a synthetic polymer product. Once cured, it becomes non-flammable and insoluble. Epoxy floors are waterproof and resistant to moisture. They are resistant to weather and most chemicals. Epoxy resin is an important component of resin industrial flooring and has been increasingly used in homes for some time.

What is epoxy resin?

First you need to answer the question of what epoxy resin is. Chemically speaking, it is a synthetic polymeric material with a characteristic structure consisting of one oxygen atom combined with two carbon atoms. Epoxy resins are not a new invention, as they were patented in 1934 by German chemist and inventor Paul Schlack and Swiss chemist Pierre Castan. Epoxy resins contain liquid components and hardeners that, when mixed together, react chemically to form plastics with good physical properties. They decided to make epoxy resins versatile. These properties are manifested in the fact that once the liquid mass has hardened, the final polymer product is non-fusible and insoluble. Epoxy suspensions can be used for laminating, bonding and pouring, as well as for impregnating various surfaces, including wood, glass, metal and concrete. The composition of epoxy resins includes a special hardener in addition to polyphenols, compounds of vegetable origin. Dyes, thinners (such as phthalates) and fillers (such as copper powder, chalk, sand and talc) are also usually added to the mix.

Properties of epoxy resin

Epoxy resins are characterized by high abrasion, scratch and impact resistance. They are also characterized by compressive strength, compression strength, tensile strength and high hardness. Among the properties of epoxy resins are also above-average resistance to moisture, heat, oils and fats, and some other chemicals such as acid and salt solutions. They are less intense in contact with chlorine, methanol or hydrocarbons, and in contact with ultraviolet or UV light. In this case, the surface of the epoxy coating may turn yellow and form a layer of dust on the surface.

Application of epoxy resin

Epoxy has a variety of applications, which is why it is so readily used in many industries. It is ideal for bonding, waterproofing and making floors. It is used in health centers, warehouses, industrial premises, garages and basements because of its durability, non-slip coating and easy-to-maintain hygienic surface.

It is great for waterproofing and decorating wood, and also works well on walls. This way they are protected from moisture. It works well as a structural adhesive for metal to protect surfaces exposed to severe corrosion and for sealing.

Epoxy resin for wood

Epoxy can be used to create clear castings, protecting and giving a subtle sheen to various surfaces. It is most often used in styling to protect wooden parts and in jewelry to hold small pieces of jewelry. Our company offers epoxy resins for wood, which, among other things, fill in the natural crevices of wood and combine with appropriate colors and dyes to make them almost imperceptible.

Epoxy resin floors

Epoxy floors are used primarily in garages, warehouses or industrial halls, but for some time now it has been increasingly used as an original decorative element in residential interiors. Interesting synthetic resin floors can be found in living rooms, kitchens, bathrooms, terraces and balconies. They can be clear or colored, applied directly to concrete or wooden floors, and protect them. The biggest advantage of resin floors is the creation of a seamless surface, which gives elegance to the interior and optically enlarges it. They are famous not only for their interesting decorative effects, but also for their high durability, hardness and resistance to mechanical damage. Resin floors withstand heavy loads well and are resistant to scratches and abrasion. Moreover, it is easy to clean and waterproof, so it can also be used in rooms with high humidity. Thin, thick or thick layers of quartz epoxy resin are used for flooring.

Disadvantages of epoxy resin

The disadvantage of epoxy resin is mainly due to two factors: price and experience. Cheaper products can yellow in sunlight and dry less well, which can lead to improper resin setting. It is also worth mentioning that cheap products can smell very strong and even suffocating. Another disadvantage to mention is the need for experience, as anyone who has worked with this material knows how many very important factors can negatively affect the final result of a given project. Because what can go wrong? It's too much humidity, too much carbon dioxide in the air, improper pouring of resin, or even improper mold making. The factors that affect the end result are many, and only experience will eliminate most of them.
