What is epoxy casting resin?
Epoxy casting resin is a two-component system of resin and hardener that cures at room temperature into a solid, clear plastic once mixed. Our system cures slowly: air bubbles have time to rise, and layers of up to 3 cm can be poured in one go. It is suitable for cast and art objects, jewellery, decoration, filling tree trunks, furniture coatings and sealing.
The key processing values
Pot life is the time during which the mixed resin remains workable.
| Mixing ratio | 100 : 47 by weight, e.g. 200 g resin and 94 g hardener |
|---|---|
| Layer thickness | up to 3 cm per pour, thicker in several layers |
| Pot life (1,000 g mix) | approx. 12 h 40 min at 20 °C, approx. 2 h 20 min at 30 °C |
| Curing | at room temperature; fully cured after approx. 14 days at a minimum of 23 °C; post-curing above 40 °C possible |
How to add glow pigments to casting resin
- Weigh out resin and hardener and stir slowly but thoroughly, including the sides and bottom.
- Let the resin thicken briefly until it is slightly thicker.
- Stir in approx. 20% pure pigment relative to the resin – not ready-made glow in the dark paint. Test on a small sample first.
- Pour and leave to cure at room temperature; remove rising air bubbles with a heat gun.
Tip: In thin, runny resin glow pigments sink, so mainly the underside glows. For a glowing surface, add the pigment to a separate top layer. You can also embed glow granules. The mixing calculator works out the right amount of pigment.
Good to know
Resin (signal word “Warning”) and hardener (signal word “Danger”) carry hazard statements: the resin irritates the skin and eyes and may cause an allergic skin reaction; the hardener is harmful if swallowed or in contact with skin and causes serious eye damage. Both are toxic to aquatic life. Wear protective gloves, protective clothing and eye protection and work in a well-ventilated area. Dispose of residues and containers in accordance with local regulations. All information is in the data sheet under safety data sheets, which we will also send you on request.
