Dynasylan® GLYMO

Dynasylan® GLYMO is a bifunctional organosilane possessing a reactive organic epoxide and hydrolyzable inorganic methoxysilyl groups. The dual nature of its 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 low­viscosity liquid with a slight terpentine­like odor. It is soluble in alcohols, ketones and aliphatic or aromatic hydrocarbons.

Processing Information
  • Dynasylan® GLYMO may be used as a constituent of an aqueous size, neat, or added to the polymer matrix as an additive.
  • A chemical modification can be achieved by reaction with suitable functional monomers or polymers.
Product Applications

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
