Product Description

Silaplane® FM-0425 is a reactive polydimethylsiloxane (PDMS) based polymer with a molecular weight of 10,000 g/mol and a Viscosity of 140-180 mPas. This reactive silicone material offers the addition of silicone-type properties to non-Silicone materials in a variety of industries including electronics, semiconductors, automotive, biotech, healthcare, and clean energy applications. It offers narrow polydispersity and a low level of chemical impurities.

Silaplane® FM-0425 mono-terminal product has a Hydroxy functional group that is reactive toward a variety of compounds and surfaces enabling chemical and physical changes to chemicals, particle surfaces and larger surface structures. Hydroxy groups are mainly reacting with Urethane and Ester compounds. The reactive functional group improves the adsorption to the filler surface and makes the inorganic filler easier to blend into the silicone binder resin. At the same time it displays high affinity for the silicone binder resin which improves the wettability between the filler and the binder. This product stabilizes the filler dispersion due to the repulsive force between fillers, achieved by silicone repulsion and the osmotic pressure effect.

Product Benefits:

  • Filler dispersion stabilization with low viscosity
  • Water/Oil repellency
  • Gas permeability (Oxygen, CO2, CH4, etc.)
  • Mold releasability
  • Anti-Abrasion resistance, Anti-fouling

General Properties
Molecular weight 10000 g/mol
Specific Gravity
Specific Gravity
Specific gravity (SG) is the ratio of the density of a substance to the density of a reference substance; equivalently, it is the ratio of the mass of a substance to the mass of a reference substance for the same given volume.

For liquids, the reference substance is almost always water (1), while for gases, it is air (1.18) at room temperature. Specific gravity is unitless.
Physical Properties
Viscosity is a measurement of a fluid’s resistance to flow.

Viscosity is commonly measured in centiPoise (cP). One cP is defined as
the viscosity of water and all other viscosities are derived from this base. MPa is another common unit with a 1:1 conversion to cP.

A product like honey would have a much higher viscosity -around 10,000 cPs-
compared to water. As a result, honey would flow much slower out of a tipped glass than
water would.

The viscosity of a material can be decreased with an increase in temperature in
order to better suit an application
