General points for all resin work
Resins are not simple to work with and you should not attempt resin art if you are not prepared to experience a learning curve. Start small and get to know your products and the correct methods.
Preparation and mixing are crucial for any resin project to be successful. Read and follow all instructions carefully. Only mix the quantity that you will use immediately as resins cannot be stored after mixing. The heat generated in a container of un-poured resin or in resin that is applied too thick can reach dangerously high levels. 

You need to take health precautions when working with resins so read safety and health instructions carefully. Avoid breathing fumes of this product. Use in a well ventilated area at minimum but an approved respirator is recommended. Avoid all skin contact and wear safety glasses, long sleeves and rubber gloves to minimise skin contact. This product is an irritant to the eyes, skin and mucous membranes. 

Greencast® Deep Clear Casting Epoxy Resin by Sicomin
  • Cast in layers between 5-100mm thick. There is no limit to the number of layers that can be added. Layers of 100mm thickness can generate too much heat in warm weather. Until you are familiar with this resin, limit layer thickness to 80mm.
  • Used to create ‘river tables’ and poured into deep moulds to create castings. Excellent for adding pigments and colourants and for submerging medium size stones and crystals in resin creations. Castings cure with negligible shrinkage and are hard and strong.
  • UV Stabilised (slow to yellow compared to non-stabilised resins).
  • Bio-based resin system making it more environmentally friendly. 37% of resin (Part A) is manufactured from renewable plant material.
  • Not approved for food contact and not suitable for heat contact or exposure above 61oC.
  • Manufactured by Sicomin in the France.
  • Mixing ratio is 100 Resin : 42 Hardener by weight or 2 Resin : 1 Hardener by volume.

The most important characteristics of this resin system

UV Stabilised but clear unpainted resin will eventually yellow outdoors.

  • UV Stabilised (slow to yellow compared to non-stabilised resins). It will still yellow if exposed to UV light or sunlight for long periods or if exposed to temperatures above 61oC. If strongly pigmented or painted then it is fine for outdoor use.

Amine blush can potentially develop if the resin cures in cold, moist conditions.

  • Do not use this resin in cold, moist conditions.
  • If amine blush does occur then take required steps to remove it. 

The liquid resin has low viscosity (thin with high flow).

  • It is usually poured into moulds or onto surfaces that have retaining sides e.g. river tables.
  • The low viscosity allows entrained air to rise up and escape easily. Torching is often not required and air is usually not a problem with this resin which is a big advantage. 

It can be applied in layers up to 100mm thick.

  • Until you are not familiar with this resin, limit layer thickness to 80mm.
  • Thicker layers may generate excess heat and cure too quickly thus giving a weaker final result.
  • This resin cannot be used in very thin layers, use in layers between 5-100mm thick. We don’t recommend thin layers below 5mm as they take even longer to cure. ​

Pot Life and Cure Time

  • Pot life can be expected to be around 1 hour (for 500g batch) at 20oC but it decreases in warmer conditions and for larger quantities. At 30oC the pot life of the same batch will be only 45 minutes.
  • Unlike many other resins, the pot life is not determined by the time it takes for the temperature to increase to 50oC. The pot life is determined by the viscosity increase and after 1 hour (for 500g batch) the resin gets too thick for air to easily rise to the surface after pouring. If you don’t use it before it starts to thicken then your pour will tend to have retained air bubbles.
  • Cure time is dependent on poured layer thickness and external temperature. Thicker layers cure faster. Expect a cure time of 24 hours for thicker layers (80-100mm) and 48 hours for thinner layers (5-10mm). Cure time will be longer in cold weather. We don’t recommend thin layers below 5mm as they take even longer to cure. ​Castings cure with negligible shrinkage and are hard and strong.
  • Cured resin resists moisture, solvents and dilute acids.
  • Cured resin can be machined and can be painted after the application of a suitable primer (remove all release agent before priming).
  • Cure times mentioned refer to the time it takes to feel hard (practical cure time). As with other resins the full cure time to maximum strength takes four week or more.

How to calculate the amount required

We recommend using a scale and resin mass as this is normally more accurate than using volume.
For a roughly square or rectangular shape multiply as follows:
Resin required in kg = Surface length in m  x  Surface width in m  x  required resin film thickness in mm x 1.13
For a roughly circular shape multiply as follows:
Resin required in kg = 3.14  x  Circle radius in m  x  Circle radius in m  x  required resin film thickness in mm x 1.13
If your rectangular surface is 60cm x 20cm and you require a film thickness of 65mm
Resin required in kg = 0.6m * 0.20m * 65mm *1.13
                                 = 8.81kg of resin
(If you select to measure out the components using volume then don’t multiply by 1.13:
Resin required in Litres = 0.60m * 0.20m * 65mm
                                 = 7.80L of resin
Now work out how much of Resin and how much of Hardener you need to give you the total requirement of 8.81kg
Ratio for this resin is 100 Parts Resin to 42 Parts Hardener
To get 8.81kg total resin:
kg Resin required = 8.81/142 * 100 = 6.204kg (or 6204g)
kg Hardener required = 8.81/142 * 42 = 2.606kg   (or 2606g)
