SupresilTM
Technology for extending the pot life of silicones to several months without changing the material properties

Our patented formulation greatly increases pot life via reversible inhibition of the crosslinking via hydrosilylation. After deposition, the inhibitors evaporate easily. Normal crosslinking occurs at mild temperatures, even below 80 °C, leading to a fast and complete curing.
What are the benefits of SupresilTM?
- reduces production costs: the pot life of silicone mixtures can be extended to several months and beyond
- enables (3D) printing: shelf stable, 1-component silicone inks can be formulated for use with a variety of printing processes including processes like dispensing, screen-printing, aerosoljet-printing, inkjet printing and others
- no change in material properties: through the complete and trace-free removal of the inhibitor during the curing process there is no change in the material or its properties
- applicable to liquid Silicone rubber (LSR) and high consistency rubber (HCR)
- suitable for all Pt-cure resins: no curing at processing temperature and normal curing at curing temperature, orthogonal with other inhibitors
- environmental: reduction in waste generation in production process
Application examples
3D printing
Standard LSR formulations are optimised for extrusion and injection moulding machines and are not suitable for 3D printing. By adjusting the rheological behaviour and extending the pot life using JOANNEUM RESEARCH‘s proprietary reversible curing inhibition, 3D printing is now possible.

LED production
Supresil™ resins reduce the processing efforts and increase the yield of colour conversion materials without changing their optical properties. The Supresil™ inhibited silicones can be mixed with colour conversion phosphors in large batches, increasing the accuracy and consistency of the colour conversion composites through improved wetting and distribution of the dispensed material and a better dispersion of the phosphors.
