Processing

1
Clean application surface
Degrease and dry the surface to be treated — a clean contact surface is important for uniform effectiveness.
2
Application
Spraying, dipping, brushing, or printing — depending on the application profile. At low viscosity, also suitable for airless spray application.
3
Apply
Uniform layer — thin for release agents, as needed for lubricants.
4
Waiting time / distribution time
For high-temperature applications, observe the drying time — check the antifoam dosage ratio.
5
Sealing + Storage
Seal remaining quantities airtight, store cool and dry — typical shelf life 36 months from manufacturing date.

Frequently asked questions about Fluid 47 V 350

Practical application and design questions — answered by SILITECH.

Bluesil Fluid 47 V 350: Linear PDMS oil (350 mm²/s) — the medium-viscosity industry standard for release agents, care products, coatings, and RTV thinners. Main applications: Release agents, paints and varnishes, care products.

PDMS (Polydimethylsiloxane) is a linear silicone fluid with high thermal stability, low surface tension, very good dielectric properties, and broad temperature resistance. The viscosity (in mm²/s = cSt) determines the field of application — low viscosities for volatile lubrication and hydraulics, high viscosities for antifoam, damping, and care conditioning.

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.

In the comparison table above, you will find related products with similar functions or related specifications. If you are unsure about the optimal choice, we will be happy to advise you — contact SILITECH with your application (desired property, substrate, processing workflow).
