Dynasylan® GLYMO

3-Glycidyloxypropyltrimethoxysilane

Dynasylan® GLYMO is a bifunctional organosilane possessing a reactive organic epoxide and hydrolyzable inorganic methoxysilyl groups.

Description

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 low-viscosity liquid with a slight terpentine-like odor. It is soluble in alcohols, ketones and aliphatic or aromatic hydrocarbons.

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

Safety & Handling

Before considering the use of Dynasylan® products please read its Safety Data Sheet (SDS) thoroughly for safety and toxicological data as well as for information on proper transportation, storage and use. The Safety Data Sheet is available after registration on our website www.dynasylan.com or upon request from your local representative, customer service or from Evonik Resource Efficiency GmbH, Product Safety Department, E-MAIL sds-hu@evonik.com.

Packaging and Storage

Dynasylan® GLYMO is supplied in 25 kg, 210 kg drums and 1.000 kg bulk containers.

In the unopened container Dynasylan® GLYMO has a shelf life of min. 12 months from delivery.
