  • Mixing Ratio 1:1 by Volume
  • 20 - 30 min pot life
  • Low Viscosity
  • Shore Hardness 20A
  • 2 - 3 Hour Cure Time
  • Food Grade Non - Toxic

Temperature Resistance – up to 220 degrees Celsius


1 Combined litre, 500ml Part A & 500ml Part B will cover approximately 1 sq mtr @ 1mm Depth


1 part A to 1 part B by volume. Mix thoroughly in a straight sided, flat bottomed container. Do not mix in an ice cream container. Use a flat ruler shaped mixing stick. Mix well scraping around the sides and base of the container.

Demoulding in around 2 to 4 hours @ 25 degrees. Low 0.01% Shrinkage on large scale moulds. If mould is adhesive after 24 hours this is due to temperature been too cold. You can fix this by placing mould in a hot room @ 25 degrees or wait 3 - 5 days and this will go away.

Shore hardness

The Shore A Hardness Scale measures the hardness of flexible mould rubbers that range in hardness from very soft and flexible, to medium and somewhat flexible, too hard with almost no flexibility at all.  

00 = Extremally soft (warm chewing gum)

70 = Extremally Hard (roller skate wheels)

Flexibility and Softness

Solid Solutions Translucent Rubber 20A shore hardness is softer and more flexible, making it suitable for applications where a high degree of elasticity and flexibility is required.

Solid Solutions Rubber 30A we offer is ideal for a wide range of moulding and casting applications. Its unique balance of softness and firmness ensures that it maintains a solid structure, making it well-suited for various casting needs. 30A Shore hardness silicone rubber is relatively firmer than 20A.


It is recommended when pouring large casting moulds to set silicone for at least 12 hours before demoulding.

Work in a well-ventilated area. Avoid contact with eyes and skin. Wear protective gloves and glasses when mixing and using. Over-exposure may cause sensitization. Uncured material can be removed with a solvent or methylated spirit followed by washing
with warm soapy water. Always wear a mask when using any solvent cleaner.

 Curing temp 25°C
 Shore Hardness  30A
 Cure 2 -3 hrs @ 25 degrees

Translucent Silicone Rubber.

I've never used this type of silicone before. However, it was easy to apply and worked great. I would like to try soon some of the clear resin that is available as well.

Extremely cheap, but extremely good

So, having used a full third of my pack i have the following impressions.
1) holds detail very well.
2) mixes extremely well. Degasses extremely fast.
3) Is quite thin. Good for undercuts. Poor for staying in my molding blocks. I'm experiencing about 15-20% wastage as opposed to 10% with my previous brand. More than made up for by the 50% reduction in price
4) takes quite a while longer to harden than the brand i'm used to. This can be useful, but is also a bit tricky to use when, for example potting electronic components. I need to work with it more to find out appropriate limits here
5) Unfortunatly, does react pretty vigiourously to the oil clay i like to fashion my vents from. Combined with the slower demoulding time, this reaction (which produces a slight stickiness) can mean that moulds need a full 24 hours cure time. Possibly fixed with a different type .of clay, although finding good clay is a real pain in the asset at the moment. Something to keep in mind when considering new products perhaps?
