- 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.
