Fastest Curing Silicone Alternatives for Mould Making

← Back to What can be used instead of silicone rubber?

If you’re seeking a faster alternative to traditional silicone rubber for mould making, several options can help you accelerate your casting projects. The right choice depends on your project’s size, level of detail, and desired turnaround time.

Speedy Solutions: Silicone Putties

Silicone putties are among the fastest curing materials for mould making, typically ready to demould within 20 to 40 minutes. These two-part pastes are easy to mix by hand (usually at a 1:1 ratio), require minimal tools, and are excellent for rapid prototyping or capturing impressions of small, detailed objects. Because of their speed and simplicity, silicone putties like I–Gum Non-Toxic Silicone Putty are ideal for quick, low-mess tasks and projects with tight deadlines.

Fast-Setting Liquid Silicones

For those who require higher detail or plan to cast more complex shapes, some liquid silicone rubbers have formulations designed to cure more quickly than standard options. Products such as Pure Mould Translucent Liquid Silicone Rubber offer working times as short as 3–8 hours while providing the detail and flexibility needed for intricate or larger moulds. These liquids still require mixing, but their reduced curing times make them efficient for both professional and hobby use.

When This Matters: Meeting Tight Deadlines

Choosing a fast curing alternative is particularly important for makers working on commissions, small batch production, or time-sensitive prototypes. Whether you’re creating custom pieces for clients or refining a design before mass production, opting for quick-setting solutions ensures you can keep projects moving without compromising on detail.
