Premium Hard Kneadable Silicone for Professional Mould-Making and Industrial Prototyping Applications
Stensil ECO 70 is a two-component, platinum-catalysed addition-cure kneadable silicone (Shore A 70) that cures at room temperature. The blue putty is easily mixed by hand at a 1:1 ratio by weight and, with a pot life of 1.5 minutes and a demoulding time of 6 minutes, allows an efficient production cycle. Its Shore A 70 hardness makes this version ideal for sturdy production moulds, industrial prototyping, technical reproduction and applications where high dimensional stability is essential.
Key Benefits
- Shore A 70 – hard version offering high compressive resistance for heavy materials and long production runs.
- Demoulding time 6 minutes – fast cure at 20 °C for industrial efficiency.
- Shrinkage <0.1% – excellent dimensional stability for precision technical applications.
- Density 1.68 g/cm³ – firm putty consistency for vertical and complex model shapes.
- 1:1 mix ratio by weight – easy to mix by hand without any equipment.
- Chemical resistance – reasonably resistant to acidic and more aggressive substances.
Typical Applications
- Industrial prototyping – sturdy moulds for technical components and machine parts.
- Production moulds – hard moulds for long production runs in metal or resin casting.
- Jewellery production – moulds for heavy metals or large pieces.
- Model making – precision reproduction of technical details.
- Restoration – hard moulds for structural ornaments and fittings.
- Dental technology – firm check bites and hard insulating layers.
Processing Instructions:
- Take equal parts of Part A and Part B by weight (1:1).
- Knead both components together thoroughly with clean hands until the colour is a uniform blue.
- Use the mixed putty within the pot life of 1.5 minutes.
- Press the silicone over or around the model and wait 6 minutes at 20 °C.
- Demould as soon as the silicone has fully cured and no longer feels tacky.
- Full strength is reached after 24 hours.
Addition-cure silicone warning: Stensil ECO is a platinum-catalysed addition-cure silicone that can be poisoned by sulphur, nitrogen, amine compounds and metal salts. These substances are found in, among other things, many latex gloves, some plasticines, lacquers, adhesives, condensation-cure silicones, one-component silicone sealants, natural rubbers and 3D-printing materials (especially stereolithography/SLA). If in doubt, test on a small area first or apply a protective layer of polyvinyl alcohol.
Silconic GmbH & Co. KG is a German manufacturer of high-quality silicone elastomers, producing in Lonsee. Since 2004 the company has been developing dental silicones under its own brands, and it is one of Europe's leading producers of RTV-2 silicones.
