Bluesil Paste 4: Universal silicone paste from the Bluesil range for diverse industrial applications — lubrication, heat transfer, vacuum sealing, corrosion protection. Main applications: industrial lubrication, vacuum sealing, corrosion protection.
Apply to clean, dry surfaces—degrease beforehand if necessary. Apply with a brush, spatula, or paste gun. Apply thermally conductive pastes thinly and evenly—excess layer thickness reduces thermal conductivity. Pastes can be diluted in aliphatic or chlorinated solvents if thin layers are required.
Store in the unopened original container in a dry, cool place — typically between +5 and +30 °C, see TDS for exact values. Consult the Safety Data Sheet (SDS) before use. Observe the expiry date on the packaging — Elkem guarantees the product's specifications only until the date shown.
