BLUESIL Fluid 47 V 300

Bluesil · Elkem Silicones · SKU 40-129

Bluesil Fluid 47 V 300 is a medium viscosity linear PDMS oil (300 mm²/s) — a proven all-rounder as an RTV thinner, lubricant, release agent and hydrophobizing component.

Bluesil/Silbione polydimethylsiloxane oils (PDMS) — chemically inert, thermally stable, with defined viscosity, suitable for use as lubricants, separators, dielectrics, hydraulic fluids, and heat transfer fluids. Fluid 47 V 300 is tailored to specific applications — the most important properties and areas of application are listed below.

Medium viscosity all-rounder

Bluesil FLD 47V300 is the medium viscosity variant of the 47V series — suitable as a thermostatic medium (−50 to +200 °C), as a thinner and plasticizer for Bluesil RTV, as a release agent and as a hydrophobizing component for powders and glass fibers.

What distinguishes Fluid 47 V 300

Medium viscosity all-rounder

Universally applicable — lubrication, release agent, thinner, hydrophobing.

Very good heat resistance

Operating range −50 to +200 °C, high combustion resistance.

Small viscosity change

Stable over a wide temperature range — no thickening in cold, no liquefaction in heat.

Water-repellent

Makes powders, fiberglass and paints water-repellent.

Weather-resistant

Oxidation-stable, UV-stable — also suitable for outdoor use.

What is Fluid 47 V 300 used for?

RTV thinner and plasticizer

Viscosity adjustment of Bluesil RTV-2 systems.

Release agent

Demolding of plastics and foundry articles.

Hydrophobization

Water-repellent treatment of powders, fiberglass, and paints.

Care product component

Polishes, waxes, floor polishes — improve shine and protective film.

Anti-stain agent

Photocopiers and printers — prevents toner buildup.

Processing

Clean application surface

Degrease and dry the surface to be treated — a clean contact surface is important for uniform effectiveness.

Application

Spraying, dipping, brushing, or printing — depending on the application profile. At low viscosity, also suitable for airless spray application.

Apply

Uniform layer — thin for release agents, as needed for lubricants.

Waiting time / distribution time

For high-temperature applications, observe the drying time — check the antifoam dosage ratio.

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 300

Practical application and design questions — answered by SILITECH.

What is Fluid 47 V 300 used for?

Bluesil Fluid 47 V 300: Medium-viscosity linear PDMS oil (300 mm²/s) — a proven all-rounder as an RTV thinner, lubricant, release agent, and water-repellent component. Main applications: RTV thinner and plasticizer, release agent, water-repellent.

What is Polydimethylsiloxane (PDMS)?

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.

How is Fluid 47 V 300 stored?

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.
