Alginate moulding rubber 100 g - Body casting

Alginate 100 G


In stock

Easy to process printing material. Due to the addition of a new natural and biodegradable fibre, this alginate is more tear-resistant than ordinary standard qualities on the market. Alginate is skin-friendly and therefore ideally suited for moulding body parts and for medical applications.

Available in 100 g, 1 kg, 6 kg and 25 kg packs.

€7.44 / st



Suitable for making face prints and other body parts. When the mould is finished, only water-curing products such as zellane, gypsum and plaster can be poured into it.


  • Use alginate at room temperature. 
  • Measure and weigh the correct amount of water and alginate. 
  • Mixing ratio is 50 g powder to 150 ml water. 
  • For a brushable mixture, use a ratio of 50 g of powder to 100 - 120 ml of water. 
  • Sprinkle the powder into the water, not the other way around! 
  • Then stir the powder and water, preferably with a small mixer. 
  • Use a low speed, max. 200-300 rpm. Manual mixing is also possible for small quantities. 
  •  Mechanical mixing gives a better result. 
  • Apply alginate to the skin or model with a flowing movement. 
  • This avoids air bubbles on the surface. 
  • Processing time 4 minutes (at 23°C). 
  • Binding time approx. 8-10 min. 
  • Application time and binding time are strongly influenced by temperature. 
  • Cold water slows down, warm water accelerates. 
  • You can adjust the fluidity of alginate by changing the powder/water ratio. 
  • More water gives a thinner mass, longer processing time and demoulding time. 
  • Less water gives a thicker mass, shorter processing time and demoulding time. 
  • If necessary, you can apply several layers on top of each other.

    Please note: always make small quantities in function of the processing time.
To keep the mould a little longer, you can put a damp cloth over it. Cleaning agent for tools and hands: water and soap. No dangerous goods.
