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
- 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
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 Information
- For substrate pretreatment, Dynasylan® GLYEO can be used as a primer either as an approximately 0.52% 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 (110 wt.%).
- A chemical modification can be achieved by reaction with suitable functional monomers or polymers.
Properties
- Physical Form
- Soluble In
- Product Reactivity
- In the presence of water, the ethoxy (OCH₂CH₃ ) groups of Dynasylan® GLYEO hydrolyze to produce ethanol and reactive silanol (SiOH) 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.
