DYNASYLAN 3403 is a bifunctional organosilane possessing a reactive organic mercaptan and a hydrolyzable inorganic dimethoxysilyl group. Bbinds 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, surface modifier or reactive reagent. Due to the methyl group DYNASYLAN 3403 is slightly hydrophobic. DYNASYLAN 3403 is a clear, colorless to light yellow liquid with a ester-like to mercaptan odor.
Used as a glass and metal primer.
Improved adhesion
Improved mechanical properties, e.g. flexural strength, tensile strength, impact strength and modulus of elasticity
Improved moisture and corrosion resistance
Improved electrical properties, e.g. dielectric constant, volume resistivity
Increased thermal resistivity
DYNASYLAN 3403 can also improve such processing properties as:
Improved filler dispersion
Rheological behavior: (e.g. viscosity reduction, Newtonian behavior)
Increased filler loading
Bifunctional organosilane possessing a reactive organic mercaptan and a hydrolyzable inorganic dimethoxysilyl group. Used as a glass and metal primer. Acts as an adhesion promoter, crosslinking agent, surface modifier or reactive reagent. Improves mechanical and electrical properties, moisture and corrosion resistance. Increases thermal resistivity. Provides better filler dispersion and rheological behavior.
