Polyform Cure and Demould Time

← Back to How long before I can remove the formwork?

If you need a quick turnaround for casting projects, Polyform polyurethane resin is a top choice due to its fast-setting properties. Here’s a practical guide to the cure and demould time for Polyform.

How Fast Does Polyform Set and Demould?

Polyform sets rapidly: after mixing, it begins to harden within roughly five minutes. It generally becomes firm enough to demould after approximately 30 minutes, allowing you to handle or inspect castings shortly after pouring. This quick process is ideal for those who value efficiency in prototyping and small-batch casting work.

Practical Tips for Successful Curing

• Mixing Ratio: Blend parts A and B at a 90:100 weight ratio for consistent results.
• Temperature Matters: Ensure the working environment is above 8–10°C as colder conditions may lengthen cure times or affect set quality.
• Mould Choice: Polyform’s high fluidity makes it well-suited for detailed silicone moulds. Avoid trying to colour this beige resin, as it is not designed for pigment addition.

When Quick Demoulding is Important

Rapid demould times matter in situations where time is limited—such as rapid prototyping, classroom demonstrations, or casting multiple parts in succession. With Polyform, you can cycle through castings quickly, maintaining productivity for your models or prototypes.
