Achieve precision and ease in mould-making with SiliCreate Quick Chromatic Alginate Powder. Our innovative formula offers a visual guide with its unique colour change from blue to purple and back to blue, indicating the perfect time to create your mould. Ideal for dental moulding, body casting, and craft applications, this alginate powder mixes effortlessly to a smooth consistency.

Key Features:

• Smart Colour Change: Signals the optimal window for mould creation with a clear colour transition.

• Adjustable Consistency: Choose your preferred texture with variable water-to-powder ratios.

• Rapid Set: Achieve a workable mould in less than 4 minutes with a pot life of under 90 seconds.

• Easy to Use: Detailed instructions ensure a straightforward process from mixing to demoulding.

• Customisable Performance: Control setting speed with water temperature adjustments and ensure a smooth mix with common kitchen tools.

• Safe and Eco-Friendly: Crafted for peace of mind, it's non-toxic, skin-safe, and environmentally considerate.

• Subtle Mint Scent: Adds a refreshing touch to your moulding experience, making the process pleasant and enjoyable.

Optimal Mixing Ratios (by weight):

• For a firmer, paste like consistency, use a 2:1 water-to-powder ratio.

• For a more fluid consistency, suitable for larger moulds or longer working times, ratios can be adjusted up to 4:1.

This flexibility allows you to control the viscosity of the alginate for various casting scenarios, ensuring that you always have the right texture for your creative endeavours.

Our Alginate comes in a 500g package and is engineered for both enthusiastic hobbyist and discerning professional.

  What is Shore Hardness?

Our Fast-20 silicone rubber is amazing for most moulding and casting applications, it’s shore hardness of 20A means it is relatively soft whilst still being firm enough to hold good structure in all applications.

The quick setting time can also be incredibly useful when quick remoulding is required or when working times are not required.

- Very easy to use with 1:1 mixing ratio.

- Reproduce very fine details with ease.

- Incredibly quick cure time of 30 minutes

  What is Shore Hardness?

Faster set. Easier handling. Solid results.

Our reformulated TC20 is a reliable, cost-effective tin/condensation cure silicone rubber designed for everyday moulding and casting needs. With a balanced shore hardness of 20A, it's ideal for flexible, medium-firm moulds used in art, crafts, and prototyping.

Less sensitive to cure inhibition, TC20 works well with a wide range of materials—making it especially user-friendly for beginners and hobbyists.

Now with faster setting and smoother mixing. Catalyst included.

Key Features

• Mix Ratio: 100:3 by weight (Base: Catalyst)

• Working Time: 30 minutes at 23°C

• Cure Time: 3–5 hours at room temperature

• Minimal Shrinkage: ~0.3%

• High Tear Strength

• Temperature Range: -30°C to +120°C

• Shore Hardness: 20A

• Colour: White

• Catalyst included

Tin Cure vs Platinum Cure

Tin cure silicones are more economical and faster to cure, with less sensitivity to contaminants that can inhibit curing—making them great for general use. However, platinum cure silicones offer greater mould life, higher precision, and options for food-safe applications. If you're after premium performance, especially for professional or high-detail projects, our platinum range is the better choice.

Use TC20 for fast, forgiving moulds where precision and longevity aren’t critical.

For professional, food-safe, or high-detail applications, our platinum cure silicones are the gold standard.

What is Shore Hardness?

SiliPutty is our flexible silicone putty that is perfect for quick impression moulds. Kneading together in a 1:1 ratio, SiliPutty sets quickly and works on a wide range of surfaces.

Ideal for small parts and features. Can also be used to create one off, custom silicone pieces.

• Mix time - 2 minutes

• Curing time - 15-45 minutes (this product is highly sensitive to temperature, cooler temperatures = longer curing times)

• Cures at room temperature (24 degrees C)

• Shore Hardness - 35A

What is Shore Hardness?

We are excited to introduce our new and improved formulation of our Medium Silicone! This updated version retains the same hardness but is now more fluid and easier to mix. Plus, it sets in just 4-6 hours, making it even more convenient for your moulding and casting needs.

Our Medium Silicone Rubber is great for most moulding and casting applications, it’s both soft but firm enough to maintain its structure which is great for most casting applications. It also works well for moulding where a solid structure is required.

- Very easy to use with 1:1 mixing ratio.

- Reproduce very fine details with ease.

- Good working time.
