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.
Properties and applications of Dynasylan GLYMO:
Dynasylan GLYMO is an essential ingredient in the products of many industries.
Examples are:
-glass fiber/glass fabric composites: as a finish or a size ingredient
-foundry resins: as an additive to polyurethane resins
-sealants and adhesives: as a primer or additive
-mineral filled composites: for pretreatment of fillers and pigments or as an additive to the polymer
-paints and coatings: as an additive and as a primer for improving adhesion to the substrate, especially glass and metal
-improved shelf life over aminosilanes in polyurethanes
Important product effects that can be achieved through the use of Dynasylan® GLYMO include:
-improved mechanical properties, such as flexural strength, tensile strength, impact strength and modulus of elasticity
-improved moisture and corrosion resistance
-improved electrical properties, for example dielectric constant, volume resistivity
Dynasylan GLYMO can also improve such processing properties as
-filler dispersion
-rheological behavior (i.e. viscosity reduction) Newtonian behavior
-increased filler loading
-non yellowing
General description
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.
GPTMS is highly reactive in water and can be used as a linking agent between the surface of the silica and the polymeric matrix.
Application
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
GPTMS is widely used as a silica precursor.
GPTMS 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.
GPTMS can used to functionalize (wrap) multi-walled carbon nanotubes (MWCNTs) which can be used as s a reinforcement in epoxy matrix nanocomposites.

The condensation of alkyltrialkoxysilanes was studied using time-dependent 1H- and 29Si-NMR spectroscopy.
The main goal was to correlate the results of these investigations with standard conditions in technical applications of the most commonly used commercial silane adhesion promoters.
Thus, experiments with 3-aminopropyltriethoxysilane (DYNASYLAN AMEO), 3-glycidyloxypropyltrimethoxysilane (DYNASYLAN GLYMO) and 3-methacryloxypropyltrimethoxysilane (DYNASYLAN MEMO) were carried out in aqueous solutions at a selected range of concentrations.
This investigation reflects a convenient way to determine the total concentration of reactive silanol groups during the course of the reaction.
Moreover, the activity of the solution in adhesion promoting processes can be monitored and measured.
