Product Description

Dycotec Materials DM-SIP-2005PU is a screen printable silver conductor paste that is used in stretchable applications such as wearable devices, sensors and medical devices. The paste can be applied to TPU(polyurethane) substrates. It offers excellent electrical conductivity and is stretchable up to 80%.

Product Benefits

• Low temperature curing temperature (120-140˚C)
• Stretchable with elongation up to 80%
• Electrical conductivity (<13 mΩ/sqr/25µm, 130oC, TPU substrate: U073)
• Low silver content with high surface coverage (247 cm2/g at 6 µm) ensuring cost effective paste system
• Compatible with Dycotec Materials stretchable encapsulation pastes

Paste Preparation

DM-SIP-2005PU is a thermoplastic silver paste system, it is supplied as a single part ready to use ink. Once the paste has been removed from the container for printing, this may introduce contamination. Please do not replace the paste in the container. The paste should be gently stirred before use avoiding incorporation of air bubbles.
