- Product Highlights
- In the presence of water, the ethoxy (-OCH2CH3 ) groups of Dynasylan® GLYEO hydrolyze to produce ethanol and reactive silanol (-Si-OH) groups which can bond to a variety of inorganic substrates.
- The organophilic glycidyl end of Dynasylan® GLYEO can react with a suitable polymer.
- Hydrolysis of Dynasylan® GLYEO is catalyzed by organic acids such as acetic acid.
- Examples of suitable inorganic substrates are glass, glass fibers, glass wool, mineral wool, silicic acid, quartz, sand, cristobalite, wollastonite, mica as well as aluminum hydroxide, kaolin, talc, other silicate fillers, metal oxides and metals.
- Dynasylan® GLYEO may be used with such polymers as epoxy, phenolic and melamine resins, polyurethanes, ABS, PBT, PS, PVAC, PVC, acrylates, polysulfides, EPDM and butyl rubber.
- Ideal adhesion promoter for aqueous adhesive and sealant systems, as well as for many glass applications.
- Dynasylan® GLYEO hydrolyzes and condenses slower than Dynasylan® GLYMO. This guar- antees signifi cantly improved stability in aqueous adhesive systems (acrylate, epoxy, latex).
- Dynasylan® GLYEO is spe- cially recommended for applications in which controlled adhesion and cohesion is particularly important, or in trendsetting ethoxy systems.
- Epoxy functionalized adhesion pro- moter with slow hydrolyzing ethoxy groups.
- Dramatic increase in stability of water- based adhesives and sealants, without negatively aff ecting epoxy functionality.
- Releases more environmentally-friend- ly ethanol when applied compared to conventional methano releasing silanes.

- Application Characteristics
Dynasylan® GLYEO is an important or even 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.
- adhesives and sealants: 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.
Important product effects that can be achieved through the use of Dynasylan® GLYEO 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® GLYEO can also improve such processing properties as
- better filler dispersion.
- rheological behavior (i.e. viscosity reduction) Newtonian behavior.
- increased filler loading.
- Processing
- For substrate pretreatment, Dynasylan® GLYEO can be used as a primer either as an approximately 0.5-2% solution in an organic solvent such as alcohol, as a constituent of an aqueous size, or neat.
- It can also be added to the polymer matrix as an additive (1-10 wt.-%). A chemical modification can be achieved by reaction with suitable functional monomers or polymers.
