When looking for epoxy resin for flooring, laminating, bonding, or protecting concrete, you may come across products from many foreign brands. However, it is worth knowing that epoxy resins are also produced in Poland, used by DIY enthusiasts, contractors, and large industrial plants alike.
The most recognizable Polish brand in this category is EPIDIAN®, produced by Sarzyna Chemical in Nowa Sarzyna.
Sarzyna Chemical specializes in the production of synthetic resins and, according to the manufacturer, is currently the only manufacturer of epoxy resins in Poland. The company has over 80 years of experience, and its portfolio includes over 1,000 base products and custom-made solutions.
What is EPIDIAN®?
EPIDIAN® does not refer to one specific product. It is an entire family of epoxy resins with different properties, viscosities, compositions, and intended uses.
The range includes, among others:
- base epoxy resins,
- modified resins,
- laminating resins,
- resins for making composites,
- bonding and repair resins,
- flooring systems,
- protective coating resins,
- industrial products,
- hardeners designed for various resins and application conditions.
Therefore, the question "which Epidian should I choose?" should always be supplemented with information about the planned application, the type of substrate, the operating temperature, the required viscosity, and the expected properties of the finished material.
Is EPIDIAN® a Polish resin?
Yes. EPIDIAN® brand epoxy resins are produced by Sarzyna Chemical in Nowa Sarzyna in the Podkarpacie region.
In the industry, the term "Sarzyna resin" is very often used. It is not the name of a single product, but a colloquial term for the resins and systems produced in Nowa Sarzyna.
The Polish origin of the products may be important for customers who pay attention to:
- domestic production,
- material availability,
- the availability of technical documentation,
- a wide range of products,
- the selection of resin and hardener for a specific application,
- product availability for individual and industrial customers.
What are EPIDIAN® resins used for?
The application depends on the selected type of resin, hardener, and any fillers and additives.
Floors and epoxy coatings
One of the best-known applications of EPIDIAN® resins is resin flooring in:
- garages,
- workshops,
- warehouses,
- production halls,
- utility rooms,
- service premises,
- shops,
- industrial facilities.
The flooring system may consist of a primer layer, a structural or self-leveling layer, the addition of quartz sand, decorative flakes, and a topcoat.
The EPIDIAN® FLOOR line, among others, is intended for flooring and includes products for priming, applying thin-film coatings, self-leveling floors, and systems with sand or decorative flakes.
Glass and carbon fiber lamination
Selected EPIDIAN® resins are used to make laminates reinforced with:
- glass matting,
- glass fabric,
- carbon fabric,
- other reinforcing materials.
Such solutions are used, among others, in the production and repair of boat components, automotive parts, tanks, housings, models, molds, and structural elements.
When laminating, the resin's viscosity is particularly important. A product that is too thick may make it difficult to properly saturate the fabric, while one that is too thin may flow excessively from vertical surfaces.
Bonding and repairs
Epoxy resins can be used for bonding, among others:
- metal,
- wood,
- glass,
- ceramics,
- concrete,
- laminates,
- selected plastics.
By adding appropriate fillers, adhesive mixtures, fillers, repair kits, and materials for filling defects can be prepared.
However, not every resin is suitable for every material. Particular caution is required with low-surface-energy plastics, such as polyethylene and polypropylene, to which standard epoxy resins have poor adhesion.
Concrete and structure protection
Epoxy resins are also used for:
- priming concrete,
- sealing substrate pores,
- applying protective coatings,
- repairing defects,
- preparing resin screeds,
- strengthening weakened surfaces,
- protecting elements exposed to water or chemicals.
The result depends not only on the resin itself. The preparation of the substrate, its moisture content, temperature, dew point, mixing ratios, and curing conditions are also very important.
Electrical engineering and industry
Selected EPIDIAN® resins are also used as potting and impregnation materials, as well as components of anti-corrosion coatings, paints, varnishes, and industrial composites.
The manufacturer's official range includes, among others, resins and hardeners for flooring, composites, pultrusion, powder coatings, liquid anti-corrosion coatings, and semi-finished product production.
Popular types of EPIDIAN® resins
Individual products differ in their properties, so the following list should be treated as a general guide, not a substitute for technical documentation.
EPIDIAN® 5
One of the most recognizable, versatile epoxy resins. It is used, among others, to prepare laminates, adhesives, potting compounds, impregnants, repair kits, and certain flooring compositions.
Due to its relatively high viscosity, in many applications it may require a properly selected hardener, reactive diluent, or the choice of a thinner resin.
EPIDIAN® 6
A basic, unmodified epoxy resin used as a base for many compositions. Depending on the hardener, it can be used for laminating, bonding, applying coatings, and other technical applications.
EPIDIAN® 52
A resin modified with a reactive diluent. It has a lower viscosity than base, unmodified resins and may be easier to apply or use for impregnating reinforcing materials.
EPIDIAN® 601 and 6011
Low-viscosity resins used, among others, for laminating, impregnating, and impregnating porous materials. The specific product should be selected according to the chosen application method and the required working time.
EPIDIAN® 624
A modified resin used, among others, in compositions requiring good flow. The application should take into account the appropriate hardener and the requirements for the finished material.
EPIDIAN® FLOOR
A family of ready-made systems intended for applying epoxy floors and coatings. It includes products for priming, applying thin-film and self-leveling layers, and decorative and industrial systems.
Resin and hardener form a single system
Epoxy resin will not cure properly without the correct hardener. A hardener should not be selected solely on the basis of price or availability.
The type of hardener affects, among others:
- mixing ratios,
- the mixture's working time,
- curing speed,
- the ability to work at a lower temperature,
- the hardness of the finished surface,
- flexibility,
- mechanical resistance,
- chemical resistance,
- color and clarity,
- the surface's tendency to develop an amine blush.
Mixing ratios should always be measured according to the technical data sheet for the specific kit. An incorrect amount of hardener may cause the material to remain soft or tacky, or fail to achieve the intended properties.
Adding more hardener is not a way to speed up the resin's drying.
How to choose the right Polish epoxy resin?
Before purchasing, it is worth answering a few questions:
- What will the resin be used for?
- Will the material be applied to concrete, wood, metal, or laminate?
- Will the application be done horizontally or vertically?
- What is the temperature at the work site?
- How much working time does the contractor need?
- Should the resin be clear or colored?
- Will the surface be exposed to UV radiation?
- Is chemical or mechanical resistance required?
- Is the material intended for laminating, potting, bonding, or flooring?
- How thick should the layer be?
Only then can the resin, hardener, fillers, and application technology be properly selected.
Is epoxy resin resistant to UV radiation?
Standard epoxy resins may change color, yellow, or become dull under the influence of sunlight. This does not always mean an immediate loss of mechanical properties, but it can affect the appearance of the surface.
In heavily sunlit areas, appropriately selected protective layers are used, such as polyurethane or polyaspartic coatings resistant to UV radiation.
Do not automatically assume that every epoxy resin is suitable for outdoor use without additional protection.
Substrate preparation is just as important as the choice of resin
Even a high-quality resin will not provide a durable result if applied to an improperly prepared substrate.
Before applying a resin system, concrete should be, among other things:
- properly cured,
- structurally sound,
- dry,
- clean,
- free of cement milk,
- free of oil, grease, and heavy soiling,
- properly ground or shotblasted,
- thoroughly dusted.
Before application, the substrate temperature, moisture content, and risk of condensation should also be checked. The surface should be sufficiently above the dew point.
