BLUESIL Paste 340
Thermally conductive silicone paste for protecting electrical circuits, for thermal seals on measuring instruments and sensors, and for sealing between resistors and metal parts in household appliances.
BLUESIL Paste 340 is a thermally conductive silicone paste based on polydimethylsiloxane with inert fillers. It is used for protecting electrical circuits, creating thermal seals for measurement and sensor technology, and for thermal bonding between resistors and metal parts in electrical devices. The paste offers good heat dissipation, chemical inertness, good dielectric properties, and a stable consistency over a wide temperature range.

Frequently asked questions about Paste 340
Practical application and design questions — answered by SILITECH.
Bluesil Paste 340: Thermally conductive silicone paste (PDMS + inert fillers) for thermal bonding between components — low viscosity change, dielectric insulating. Main applications: Electronic thermal bonding, sensor thermal sealing, household appliance resistors.
Apply to clean, dry surfaces — degrease beforehand if necessary. Application with brush, spatula, or paste gun. For thermal pastes, apply thinly and evenly — excessive layer thickness reduces thermal conductivity. Pastes can be diluted with aliphatic or chlorinated solvents if thin layers are required.
Store in the unopened original container in a dry, cool place — typically standard between +5 and +30 °C, exact values see TDS. Consult the Safety Data Sheet (SDS) before use. Observe the expiration date on the packaging — Elkem guarantees the sales specifications only up to the stated date.
