Frequently asked questions

In general, the products last for several years. However, as soon as the containers are opened and air reaches the containers, crystallization of the products may occur after a few weeks. Storage in a cool, dry environment and well sealed containers is most important. Then the solvent-free products have an almost unlimited shelf life. If the material is more than one year old, you should do a small test to make sure it still reacts as expected.

The white or crystallized product may form if the resin is left to stand, freezes or is exposed to air contact for an extended period of time. To remove crystallization, simply heat the resin to about 45°C for an hour or two. This should put it back in a clear state.

With Liquid Plastic no special measures are required to get rid of air bubbles as it releases the air by itself due to its long curing time and low viscosity. If you pour over a surface that can still release air during the three-day curing process, these bubbles can be trapped. Sealing is recommended in this case.

UV Poxy is a much thicker and faster curing epoxy that requires special attention to bubbles. A burner or a hot-air dryer is recommended to remove surface bubbles. Slow mixing of the product helps to avoid excessive air entrapment.

The use of a pressure vessel is suitable for all our epoxy products. As a general rule, if you work with heat and epoxy, you must wear a respirator.

You may have added too much hardener or made a gross mistake in the mixing ratio. It is also important to mix both components carefully for at least 3-5 minutes. If your room is colder than 21°, it may take a little longer and you should warm up the casting a little. Depending on how thick the layer thickness is, there may also be deviations in the curing time.

UV Poxy was developed for thin layers and fills small cracks. It should be used for castings not thicker than 6 mm. It has a much shorter pot life, which is only 10 to 15 minutes.
In contrast, Liquid Plastic is a casting resin developed for encapsulation and casting. It has a 3-day curing time and can be cast in any volume. However, not more than 4.5 cm thickness per casting.

The Ecopoxy products UV Poxy and Liquid Plastic are crystal clear after the curing process. The colour can be stained with various pigments.

No problem! After approx. 24 hours the exothermic reaction is completed and the heat development decreases. The rule of thumb is, if you can make a fingerprint in the epoxy without something sticking to the finger, you can pour again and the epoxy will chemically bond with the previous layer. If the point is exceeded, sand the surface of the previous layer with abrasive paper (180-220 grit). This creates a rough surface on which the next epoxy layer adheres. Cleans the surface after sanding with denatured alcohol to remove all dust from the sanding. After that, you can pour the next 4.5 cm. Per layer max. 4.5 cm.

In general, any machining is possible. Grinding, drilling, planing, milling, sawing etc.. Please note a low feed rate, low speed, small stock removal. Large heat development is to be avoided, if possible.

Basically, epoxy does not require a surface finish. In most cases, however, it still makes sense or is desirable.
For an oiled surface we grind the surface up to grain size 2000. Many work with Osmo or Rubio, but in general any hard wax oil should work.
For a varnished surface we sand the surface up to grain 320 and varnish with PU varnish in several layers.
For an epoxy coating we grind the surface up to 320 and cover the whole surface with a 1-3 mm thin layer of UV Poxy.
