Product Description

Dycotec DM-CAP-4512S is a thermoplastic carbon paste for flat-bed screen printing. The paste allows fast drying at low temperature (100-120˚C for 10 mins) with a sheet resistance of <30 Ω/sqr/25µm. The paste can be used for production of heater, sensor, automotive, keyboard and graphic overlay applications. It also used as protective overcoat for silver conductive printed layers.

Product Benefits

• Good flexibility
• Low temperature drying
• Compatibility with low temperature substrates such as PET
• Able to withstand high temperature use eg heaters
• Excellent duarbility and hardness for use as silver conductive paste overlayer

Paste Preparation

Gently stir before use. Avoid rapid stirring to prevent air entrapment during the stirring process. Once the paste has been removed from the container for printing, this may introduce contamination. Please do not replace the paste in the original container and keep the lids tightly sealed with the inner cap after paste transfer to minimise solvent evaporation.
