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
