The epoxy resin belongs to thermosetting resins with excellent mechanical properties and chemical resistance.
The epoxy resin consists of two components:
- Epoxy base
- Epoxi hardener
It has a much higher mechanical strength compared to polyurethane resins. But in contrary its curing time is much longer. Normally, it takes 1-2 days after that you can demould it.
It is typically used for:
- Casting of spare parts
- Composite material as matrix
- Coating of surfaces,
- Mouldmaking and
- Nowadays it’s highly populaire for preparing home made jewelery
The epoxy resins can also be distinguished and categorised according to consistency and functional areas as follows:
- epoxy casting resin
- epoxy foam epoxy
- coating resin epoxy
- laminating resin
- kneadable epoxy paste

The price of epoxy resins:
consists of the cost of the two components, the shipping and the packaging costs.
The hardener is the most costly part among those, so in addition to environmental considerations, this should be treated with the utmost precaution.
The prices in our webshop are not comparable to those of industrial resins which are offered for other purposes, such as resins for industrial floors e.g..
The price of our products without shipping costs, packaged in small quantities and developed for manual processing, is in between of about 5 and 10 Euro / 100 grams.
The prices increases in the following rank.
- Epoxi modelling paste
- Epoxy foam
- Jewelry Resin
- Epoxy casting resin - variable hardness
- Glass varnish
Storage of epoxy resin:
- The best way is prevention, that means you should only buy as much as you use up quickly.
- Wipe the bottle and caps before usage in order to avoid contamination of the epoxy resin components. Otherwise store it free of dust.
- The storage temperature should be between 15 and 25 °C.
- Store it in a dark place, but by no means do expose it to sunlight.
- When you open the bottles first, date the labels, which later helps you remember the age of the resin.
- Do not refill any material leftovers in the bottle.
- Make sure that the caps are not interchanged. To do this, you may want to use a color indicator if the bottles are not fitted up already from the factory.
- You should pay more attention to the hardener component as it is more sensitive to environmental impacts and vica versa it is also very harmful to the environment.
- Keep both components in airtight storage.
- In case the resin component has crystallized, it can be reversed by heat treatment (about 50-60 °C).
All of castable epoxy resins listed above have the following main properties:
- Extremely strong plastics with a high heat resistance far beyond thermoplastics.
- The hardened material has a high chemical resistance.
- They adhere well to most materials, see list below
- Virtually zero volume shrinkage (except epoxy foam) during the curing process.
Applicable fillers, additives and auxiliary agents:
- Thixotropic powder agent which greatly increases the internal viscosity of the epoxy resin. Obviously, this is only needed for the epoxy casting resins, but not for the modelling paste.
- Coloring pigment. Be sure to apply only epoxy resin-compatible paints.
- Fiberglass to manufacture composites and similar plate and shell structures.
- Glass balloon for density reduction
- Various metal powders, especially aluminum, to increase the thermal conductivity and possibly to change the appearance
- Various minerals that do not react with epoxy resin. E.g. granite, marble powder.
- The hardener components of the epoxy resin is more dangerous, so pay special attention to it.
- Carefully read and follow the safety and warning instructions included in the product packaging.
- Only work in a well ventilated room.
- Wear vinyl rubber gloves, safety gloves, protective clothing, active filter mask, goggles.
- In case of contact, immediately wipe skin with a dry cloth, then wash with plenty of soap and water. But do not use solvent liquid or nail brushes. They both facilitate the absorption of the resin components.
- Inhalation of vapors should be avoided at all times, also outside active working time, eg. when transfusing components into another bottle.
- Eating and drinking is prohibited during material handling.
- In case of contact with eyes, rinse immediately with plenty of water and visit the doctor immediately.
- Avoid release to the environment. In particular, the hardener component is harmful to aquatic life.
- When collecting empty containers, dispose of used tools separately and dispose of in an appropriate chemical waste bin.
