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
Tip for perfect castings: Before pouring, seal the pores of porous materials with a suitable primer to prevent bubbles from forming. Mix by weight 2:1 (A:B) and work at a stable temperature without fluctuations.

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)

More about the FLOWERA resin series can be found, for example, in the article FLOWERA Resin Series.

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.
