DYNASYLAN GLYMO is a bifunctional organosilane possessing a reactive organic epoxide and hydrolyzable inorganic methoxysilyl groups.
The dual nature of DYNASYLAN GLYMOs reactivity allows DYNASYLAN GLYMO to bind chemically to both inorganic materials (e.g. glass, metals, fillers) and organic polymers (e.g. thermosets, thermoplastics, elastomers), thus functioning as an adhesion promoter, crosslinking agent and/or surface modifier.
DYNASYLAN GLYMO is a colorless low-viscosity liquid with a slight terpentine-like odor.
DYNASYLAN GLYMO is soluble in alcohols, ketones and aliphatic or aromatic hydrocarbons.
DYNASYLAN GLYMO is a bifunctional organosilane with three methoxy groups on one side and an epoxy ring on the other.
The methoxy groups bind well with glass substrates creating a 3D matrix.
The epoxy group is reactive with amides, alcohols, thiols and acids.
DYNASYLAN GLYMO is highly reactive in water and can be used as a linking agent between the surface of the silica and the polymeric matrix.
Applications of DYNASYLAN GLYMO:
Pre-treatment of carbon steel with 3-(Glycidoxypropyl)trimethoxysilane enhances the dry and wet adhesion while reducing the cathotic disbondment rate of an epoxy coating.
DYNASYLAN GLYMO is widely used as a silica precursor.
DYNASYLAN GLYMO alone with tetraethylortosilicate (TEOS) can be blended with chitosan for use as a filler for polymeric scaffold for bone tissue engineering.
DYNASYLAN GLYMO can also be coated on the surface of aluminium alloy to protect from corrosion.
DYNASYLAN GLYMO can used to functionalize (wrap) multi-walled carbon nanotubes (MWCNTs) which can be used as s a reinforcement in epoxy matrix nanocomposites.
