Bio Casting Epoxy Resin – Slow Hardener Kit
$34.85 – $875.00
In-Store/Phone Orders (per unit/metre): $42.15 - 878.30
Perfect for river tables, deep pours and embedding pieces, our Bio Casting Epoxy Resin is a solvent free, water clear and low viscosity.
The bio-based formula is an Eco-friendly alternative which utilises renewable resources and reduces the levels of volatile organic compounds into the atmosphere. Bio Casting Epoxy Resin is optimised for clarity and air release to create crystal clear casting for hobby and art applications. The Fast Hardener is recommended for smaller, fast turnaround casting up to 20mm in thickness, whilst the Slow Hardener is suitable for larger applications up to 50mm in thickness, where a longer working time is required.
43 parts hardener to 100 parts resin by weight
50 part hardener to 100 part resin by volume
Note: Care should be taken when dispensing and mixing. Do not attempt to control the cure time by altering the hardener ratio. Please note that the room temperature will affect cure characteristics. Measure and mix Bio Casting Epoxy Resin with hardener using our range of measuring and mixing equipment.

*At lower temperatures the resin will be thicker making it harder to mix and less able to release air bubbles during cure. The resin will also take longer to cure. In temperatures 15-20°C a heat will be necessary to remove air bubbles. Use below 15°C is not recommended.
Use two clean plastic containers of equal volume to measure the correct proportion of resin and hardener. Pour the contents of both into a larger container and stir the two ingredients thoroughly, for at least 3 minutes –longer in cooler temperatures. Tip the mixed resin and hardener into a second large container and thoroughly mix again for a further 1-2 minutes. Ensure you stir the material slowly to keep air entrapment to a minimum.
Air bubble release is greatly enhanced by the use of a small heat gun or mini gas torch. Hold the torch approximately 100 to 150mm off the surface and keep moving the flame across the surface. Heat can be applied as many times as needed in the 30 minute working time. Inspect and remove any lint with tweezers. Bio Casting Epoxy should be cured in a warm 25°C, dust free area.
