Choosing the right epoxy resin for your project means understanding the differences in how art and casting resins gel. Each type has been engineered for specific applications, which is crucial when creating artwork or tackling deep-pour projects.
Why Art and Casting Resins Gel Differently
Artistic resins such as Art Pro Deluxe are formulated with a high viscosity, resulting in a thicker consistency. This slows down the gelling process, giving you plenty of open time for detailed designs, like fine linework or layered colour effects, without your work setting prematurely.
In contrast, casting resins are lower in viscosity and tailored for deep pours—often up to several centimetres thick. These resins require more careful management of pour depth and temperature, as they’re optimised for slow gelling to prevent excessive heat build-up and mitigate the risk of cracks or cloudiness in bulk pours.
Choosing the Correct Resin for Your Project
When working on surface art, coasters, or decorative trays, a high viscosity art resin gives greater control and minimises unwanted blending of colours. For example, Art Pro Deluxe allows you to build crisp lines and defined effects without worrying about designs losing their shape as the resin gels.
If you’re pouring river tables, large blocks, or embedding objects in thick layers, a casting resin like EpoxyTable 5-Five is better suited. Its slow gelling and low exothermic reaction support bubble-free, clear results, even in layers up to 5cm.
When This Matters Most
- If your project involves detailed pattern work, choose a high viscosity art resin for best results.
- For thick castings, always use a casting resin designed for deep pours, following the recommended layer thickness to avoid unexpected gelling or heat issues.
