Water Clear Casting Resin

Water Clear Cast Polyester Resin is a versatile, transparent casting resin ideal for embedding specimens, producing paperweights, trophies, novelty items, and decorative objects. It cures to a water-clear finish that showcases whatever is cast inside it, making it a popular choice for both craft and small-scale production applications.

This is a polyester-based casting resin, offering a straightforward and cost-effective solution for clear casting work. It is catalysed using MEKP at between 0.5 - 1%, giving a pot life of approximately 20 minutes at 20°C. To minimise the risk of cracking in larger pours, it is recommended to use the minimum catalyst level and to cure the casting in a water bath.

Available in 1kg, 5kg, 20kg, and 230kg quantities, it suits everything from one-off hobby projects to high-volume production runs. The 230kg barrel option makes it particularly cost-effective for manufacturers and trade users casting at scale.

For projects requiring deeper pours, greater clarity, or improved UV resistance, our PureCast Water Clear Epoxy range offers an epoxy-based alternative. Order online today with fast UK delivery from CFS Fibreglass.
