⚡ At a Glance
- • Cure Speed: 30–40 minute working time, cures in around 3–6 hours at 25°C
- • Best for: Hobbyists and makers testing silicone mould-making with small to medium pieces
- • Not ideal for: Large-scale commercial moulds or high-volume production runs
Fast-curing, platinum-cured silicone supplied in a 230g trial kit with a 1:1 mix ratio by weight. Starter accessories are included and the translucent rubber accepts pigments for coloured moulds.
Fine detail reproduction - with low-viscosity platinum-cured silicone
Low-viscosity silicone allows trapped bubbles to rise and dissipate naturally within a couple of hours, removing the need for vacuum degassing. Platinum cure chemistry minimises shrinkage and preserves tiny surface textures.
Highly detailed textures and tiny features are captured accurately, making small sculptures, jewellery or miniature parts reliable to cast. Demoulding tends to be clean with a non-sticky finish, according to user feedback.
Quick turnaround for small projects - thanks to a fast cure and predictable working time
The two-part system mixes at a 1:1 ratio by weight and offers a 30–40 minute workable window before crosslinking accelerates. Typical room-temperature cure completes in about 3–6 hours depending on mould thickness, with optional heat to speed the process.
Complete a making, curing and demoulding cycle within the same day for thin moulds, so small runs and rapid prototyping stay efficient. Predictable timings help plan casting sessions without long waits.
Beginner-friendly mixing and pouring - with included measuring tools and simple instructions
The kit supplies two 100ml measuring cups, two stirring sticks and disposable gloves, while a 1:1 mix ratio reduces calculation errors. Stirring for around three minutes, scraping cup sides and bottoms ensures thorough mixing.
Beginners can get usable results straight away without specialised equipment, lowering the barrier to try-making silicone moulds. The included tools cover essential steps from measuring to pouring.
