Product detailed description
Crystal Resin FLOWERA 100-72-550 UV++ – for dried flowers and beetles
FLOWERA 100-72-550 UV++ is a low-viscosity, crystal-clear epoxy resin designed for casting dried flowers, beetles, insects, and other botanical materials. Low viscosity penetrates fine details perfectly and creates a smooth, high-gloss surface after curing, making flowers and beetles appear as if under a magnifying glass.
Advantages
- Ultra clear resin with high resistance to yellowing (UV++)
- Very good self-venting – minimum bubbles around flowers and insects
- Low viscosity for perfect casting of delicate structures and details
- Long processing time – comfortable arranging of flowers without stress
- After pouring and curing, a perfectly glossy, crystal-clear surface
Suitable applications
- Casting height: up to 100 mm
- Material: dried flowers (botanicals), leaves, grasses, small twigs, beetles, insects, and other botanical objects
- Product types: paperweights, blocks with flowers, decorative cubes and spheres, small bowls, and 3D objects
Recommended moulds
- Silicone Moulds – Small Decorations: spheres, cubes, smaller 3D shapes, pyramids, crystals, paperweights
- Silicone molds – larger decorations: larger spheres and cubes, taller blocks, pyramids, letters, and numbers
Properties and Technical Parameters
| Type | Two-component epoxy resin (A – resin / B – hardener) |
| UV stability | UV stable ++ |
| Clarity | Ultra Clear |
| Viscosity after mixing A+B | 550 mPa·s (indicative scale: 300 mPa·s = extra low viscosity → 9000 mPa·s = extra high viscosity) |
| Mixing ratio (by weight) | 2 : 1 (A : B) |
| Mixed volume at once | up to 20 l |
| Max. layer height | up to 100 mm |
| Processing time | approx. 18 hours |
| Curing time | approx. 72 hours (depending on temperature and material quantity) |
| Processing temperature | ideally 22–23 °C (do not drop below 20 °C) |
| Hardness after curing | approx. 85 Shore D (for comparison: 56 Shore D = medium hard, 90 Shore D = very hard) |
| Finishing | sanding and polishing |
Pigmentation and Colouring
For transparent colouring, use resin dyes designed for epoxy systems. For castings with dried flowers and insects, a clear variant or a light tint is usually chosen to highlight the details.
Packaging
- 1.4 kg (total of components A + B)
- 0.7 kg (total of components A + B)

Usage notes
- When casting porous materials (e.g., wood, paper, some flowers), first seal the surface with a primer to prevent bubbles from releasing during curing.
- The processing temperature (mixing, casting) must not fall below 20 °C.
- During curing, do not expose castings to temperature fluctuations – they negatively affect the appearance of the surface.
- The mixing ratio is by weight. Both components should therefore always be weighed – we do not recommend volumetric measurement.
