Platinum silicone vs tin silicone – the difference explained

Almost all pourable silicones belong to one of two families. The difference lies in how they cure, and that determines shrinkage, mould life, food contact and what you need to watch out for during processing.

Tin silicones (condensation-cure silicones) – affordable and forgiving

Tin silicones, also known as condensation-cure silicones, cure with a tin catalyst in the B component (the curing agent). A small amount of alcohol is released during curing. The mixing ratio is usually 100 parts A to 2 to 5 parts B by weight.

Advantages of tin silicones:

• ✓ Cheaper than platinum silicones
• ✓ Not sensitive to inhibition, so you can cast them on almost any model
• ✓ Ideal for soap moulds, candle moulds, plaster moulds and concrete moulds
• ✓ Working time and cure can be controlled through the choice and dosage of the curing agent

Disadvantages of tin silicones:

• × Slight shrinkage during and after curing, due to the release of alcohol
• × Moulds age faster and become harder and more brittle over time
• × Not suitable for food contact
• × The curing agent contains tin compounds – always read the safety data sheet and wear gloves

Platinum silicones (addition-cure silicones) – shrink-free and for demanding applications

Platinum silicones or addition-cure silicones cure via a platinum catalyst without releasing any by-products. The mixing ratio is usually 1:1 or 10:1 by weight, and you can accelerate the cure with heat.

Advantages of platinum silicones:

• ✓ Virtually shrink-free, often less than 0.1 per cent
• ✓ Longer mould life and more stable mechanical properties
• ✓ Good resistance to aggressive casting resins such as epoxy and polyurethane
• ✓ Variants with food contact documentation and variants with skin contact documentation available
• ✓ Also available as crystal-clear, ultra-soft, kneadable and foaming variants

Disadvantages of platinum silicones:

• × More expensive than tin silicones
• × Sensitive to inhibition: the silicone will not cure, or cures tacky, on contact with sulphur (sulphur-containing modelling clay, latex), tin compounds (condensation-cure silicones), amines and some 3D printing resins, among others. If in doubt, always test on a small area first

Other forms of silicone

• → Pourable: flows out and degasses, for cast moulds and encapsulation
• → Spreadable or brushable: stays in place on vertical surfaces, for skin moulds and large objects. Many pourable silicones can be made spreadable with a thickener
• → Kneadable: mix and press by hand, without scales and without a mould box
• → Gels: extremely soft, for electronics, damping and realistic tissue
• → Foam: expands during curing, for lightweight filling and potting
• → RTV-1: one-component silicones from a cartridge or tube that cure with atmospheric moisture, for bonding, sealing and coating
• → HTV and HCR: solid silicone rubbers that vulcanise under heat and pressure in a press

Tips for the best result

• ✓ Always weigh on scales rather than measuring by volume, unless the manufacturer states otherwise
• ✓ Stir component A thoroughly before weighing, as fillers can settle
• ✓ Preferably work at around 20 to 23 °C. Cold slows down the cure, heat speeds it up
• ✓ Degas in a vacuum chamber or pour in a thin stream from a single point to minimise air bubbles
• ✓ When casting silicone onto silicone, always use a release agent, otherwise they will bond together
• ✓ When working with platinum silicones on an unknown model, always carry out an inhibition test first

Frequently asked questions

Which silicone is best for beginners?

For most beginners, a condensation-cure silicone with Shore A 20 is the best start, such as the Condensatie 20 Universeel or the Starterskit. It is affordable, forgiving and not sensitive to inhibition. If you are casting epoxy or polyurethane, or want a mould that lasts a long time, choose an addition-cure silicone.

Can I combine addition-cure and condensation-cure silicones?

Not in a single mix. Tin residues from condensation-cure silicones can prevent addition-cure silicones from curing. You can often cast addition-cure silicone against a fully cured condensation mould, but test this on a small area first.

Which silicones are food-safe?

Only addition-cure silicones with an appropriate declaration or test report are suitable for contact with food. Which documentation applies to which product is stated on the product page and in the culinary collection. Condensation-cure silicones are never suitable for food contact.

What hardness do I need?

The softer the silicone, the easier it is to demould undercuts and fine details. The harder it is, the more dimensionally stable and wear-resistant the mould. For most moulds, the best choice lies between Shore A 15 and 30. For concrete and heavy casting materials, choose Shore A 30 to 50; for skin and SFX, a Shore 00 silicone instead.
