Platinum-Cure Formula

Unlike cheaper tin-cure alternatives, this platinum-cure silicone offers exceptional durability and resistance. It handles temperatures up to 150°C, making it perfect for various casting materials including some low-melt metals and hot resins.

Minimal Shrinkage

With only 0.03% shrinkage, your moulds stay true to the original. This precision matters when you're working on miniatures with fine details or creating jewellery pieces where accuracy is everything.

Tear Resistance

Once cured, this material achieves 6 N/mm tear resistance. That means you can demould complex shapes with undercuts without worrying about ripping your mould apart. It flexes when you need it to, but stays strong where it counts.

Miniature & Model Making ⚔️

Perfect for tabletop gamers and model makers. Press it onto your converted miniature parts, scenic bases, or custom details. The fast 10-minute cure time means you can produce multiple copies quickly. Works brilliantly with resin casting, plaster, and even some low-temperature metals.

Real example: Sculpted a unique shoulder pad for your Space Marine? Make a mould and cast 10 identical copies for your whole squad.

Jewellery Production 💎

Create master moulds for resin jewellery, polymer clay pieces, or metal casting. The detail capture is sharp enough for intricate patterns, textures, and small decorative elements. Many jewellery makers use this for producing small batch collections.

Real example: Design one pendant master, create a mould, then cast 20 pieces in different coloured resins for a market stall.

Prototyping & Custom Parts 🔧

Need replacement parts for vintage models, custom grips, handles, or small mechanical components? Press-mould the original and cast duplicates. Useful for repairs, modifications, or small production runs.

Restoration & Ornamental Work 🏛️

Restoring damaged plasterwork, decorative mouldings, or period features? Take an impression from an intact section and recreate missing pieces. The low shrinkage ensures faithful reproduction of architectural details.

Orthotic & Prosthetic Applications 🦶

Used by professionals for creating custom insoles, impression moulds, and fitted components. The material's flexibility and precision make it suitable for body-contact applications (though not medical grade).

Step-by-Step Process

❌ NO Latex Gloves

This is the most common mistake. Use vinyl or nitrile gloves only. Latex contains sulphur compounds that prevent platinum-cure silicone from setting properly. You'll end up with sticky, uncured mess. Don't learn this the expensive way.

❌ Watch Out for Sulphur

Some materials contain sulphur that interferes with curing: certain clays (especially oil-based), some rubbers, and older tin-cure silicones. If you've used these on your master, the mould might not cure properly in those spots.

Quick test: try a small amount on an inconspicuous area first. If it cures normally after 15 minutes, you're good to go.

❌ Clean Your Master

Oils, dust, moisture, and residues affect detail capture and can prevent proper curing. Give your piece a wipe with isopropyl alcohol and let it dry completely before making the impression.

What's in the Box

You'll receive the official Green Stuff World packaging containing:
• Component A: 100g
• Component B: 100g
• Total: 200g of silicone putty

Package dimensions: approximately 18cm × 10cm × 5cm | Gross weight: ~230g

How to Store It

Keep both components in their original sealed containers. Store in a cool, dry place away from direct sunlight and heat sources. Kitchen drawer or craft room shelf works fine—you don't need special conditions.

Shelf life: Minimum 12 months when stored properly in unopened containers. Once opened, use within 6-8 months for best results. Make sure lids are tightly sealed after each use.

Q: What if my mould didn't cure properly?

A: Check three things: Were you wearing latex gloves? Is your master piece made from sulphur-containing material? Did you mix thoroughly for the full 30 seconds? Nine times out of ten, it's one of these. Test on a small scrap first if you're unsure about compatibility.

Q: Can I use this for really tiny details?

A: Absolutely. The detail reproduction is excellent—you'll capture textures, panel lines, rivets, and fine engravings. Miniature painters use this for copying intricate conversion bits all the time. Just make sure your master is clean and dry.

Q: How many casts can I get from one mould?

A: Depends on your casting material and technique, but typically you're looking at 20-50+ casts from a well-made mould. With resin or plaster, even more. The tear resistance means these moulds last surprisingly long, especially if you're careful during demoulding.

Q: Is it actually safe to use?

A: Yes. It's non-toxic and odourless once cured. Work in a normally ventilated space (no special extraction needed), wear gloves during mixing, and you're fine. It's not food-safe certified, so don't use it for making chocolate moulds or anything that will touch food.

Q: Can I make the mould thicker for durability?

A: Yes, and you should. Aim for at least 3-5mm thickness around your master. Thicker moulds (8-10mm) last longer and handle more aggressive demoulding. You can build up layers—just make sure each layer bonds properly to the previous one.

Q: What temperature can the cured mould handle?

A: Up to 150°C continuously. This covers most resin systems, plaster, some polyurethanes, and low-melt metals. Don't pour molten lead or anything extreme into it, but for typical hobby casting, you're well within safe limits.
