Vinyltrimethoxysilane oligomer

Silane USi-O401

Vinyl Silane Oligomer

Product Description

Vinyl Silane Oligomer; Degussa DYNASYLAN 6490

Typical Technical Data

Appearance: Colorless transparent liquid

Density(ρ20, g/cm3)：1.080±0.010

Specific Gravity (ρ20°C,g/cm3): 1.4200±0.0050

Viscosity(mPa·s): ≤5

Applications

USi-O401 is an excellent adhesion promoter between inorganic fillers (e.g. kaolin, MDH, ATH) and organic

polymers (e.g.EPDM, EVA, PE).

The high boiling point of USi-O401, together with its high flash point, gives it outstanding advantages with

respect to safety and handling during processing.

From an environmental viewpoint it should be noted that the amount of released hydrolysis methanol (VOC) is significantly reduced compared to monomeric vinyl silanes.

Packaging
