Dynasylan® GLYMO

1 of 42 products in this brand
Dynasylan® GLYMO is a bifunctional organosilane, featuring a reactive organic epoxide and hydrolyzable inorganic methoxysilyl groups. This dual reactivity empowers Dynasylan® GLYMO to chemically bond with both inorganic materials (e.g., glass, metals, fillers) and organic polymers (such as thermosets, thermoplastics, elastomers). It functions as an adhesion promoter, crosslinking agent, and surface modifier.

Features & Benefits

Reactivity
  • In the presence of water, the methoxy groups of Dynasylan® GLYMO hydrolyze to form reactive silanol groups which can bond to a variety of inorganic substrates.
  • The organophilic glycidyl end of Dynasylan® GLYMO can react with a suitable polymer.
  • Hydrolysis of Dynasylan® GLYMO can be catalyzed by organic acids such as acetic acid.
  • Examples of suitable inorganic substrates are glass, glass fibers, quartz, cristobalite and metals.
  • Dynasylan® GLYMO may be used with such polymers as epoxy, phenolic, polyurethanes, PVAC, acrylates, polysulfides.

Application Characteristics

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.
Processing
  • 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.
