Super Low Viscosity Resin: Achieving Bubble-Free Castings

Why Viscosity Matters for Bubble-Free Castings

Viscosity describes the resin’s thickness and flow rate. Super low viscosity epoxy resin flows easily, allowing trapped air to rise and escape before the resin cures. This characteristic greatly reduces the risk of bubbles becoming trapped in the finished piece, particularly when working with deep pours or embedding objects. If clarity is your goal, opting for a resin formulated for low viscosity will give you a much greater chance of a flawless finish.

Choosing the Best Resin for Your Project

• Deep pours (up to 10cm): For tasks like river tables or large-scale castings, a product such as the Epoxytable 10-Ten Deep Pour Epoxy Resin offers excellent bubble release thanks to its super low viscosity and longer working time.
• Shallower applications (up to 2cm): For jewellery, art pieces, or casting in moulds, “Trasparente” is a multipurpose clear epoxy resin with a self-levelling, ultra-clear result, ideal for projects up to 2cm thickness per pour.

When selecting a resin, consider the maximum recommended pour depth and always check the manufacturer’s guidelines to ensure optimal results.

When Super Low Viscosity Is Essential

Low viscosity resin is particularly important when pouring thick layers or embedding inclusions, such as decorative objects or memorial items. Projects requiring flawless transparency—like tabletops, large art installations, or memorial castings—benefit most from using such specialised formulations to deliver the clearest possible result.
