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.
