What are the curing times for 3481 Silicone Rubber (Professional Grade)?

We supply three options of our professional grade 3481 silicone rubber kit with differing cure and working times, as follow:

• Standard: Working time of 90-120 minutes | Cure time of 24 hours | Superior polyester resin resistance
• Fast: Working time of 30-60 minutes | Cure time of 8 hours
• Very Fast: Working time of 8-15 minutes | Cure time of 2 hours

Cure time refers to the length of time needed for something to fully set, whereas ‘working time’ is the effective pot life of your mix before it starts to become unworkable.

NB: Cure times listed above can vary due to various factors (e.g.: room temperature, etc).

 

Why choose 3481 Silicone Rubber (Professional Grade)?

Why choose the 3481 professional silicone for your project?

• It’s been around for 30 years and has what’s known as a “proven archive life”. This means that your moulds will stand the test of time.
• This grade has a lower shrinkage rate when fully cured, so basically it holds its shape better once set.
• It is more elastic than our standard grade, making it more stretchy & less likely to rip when de-moulding your work.
• It is tougher than our standard grade, meaning it will stand up to the rigours of your studio.

If your budget will stretch to it, then we always recommend using our professional grade 3481 silicone, especially if you are working on more intricate pieces such as a glove moulds, busts or ornate shapes.
