Dynasylan® 2101

3-Ureidopropyl(trimethoxysilane) (pure compound)

Typical Applications

The dual nature of its reactivity allows Dynasylan® 2101 to bind chemically to both inorganic materials and organic polymers.
In the presence of water, the methoxy (Si-OCH₃) groups of Dynasylan® 2101 hydrolyze to form reactive silanol (Si-OCH3) groups, which can bond to a variety of inorganic substrates.
Examples of suitable inorganic substrates are:

glass
glass fibers
glass wool
metals
and various fillers

The organophilic ureido group of Dynasylan® 2101 can react with a suitable polymer.
Examples of suitable polymers are:

Thermosets like epoxy, phenolic, furanic and melaminic resins
Thermoplastics like PA, PBT, EVA, PPS, PE, PP, PVB, acrylates
Elastomere like silicones

Dynasylan® 2101 finds application in the products of many industries.
Examples are:

as a size constituent for glass fiber/glass fabric composites
as an additive to foundry resins and abrasives
as an additive to thermoplastic compounds
as an additive for adhesives and sealants
as an additive and / or primer for paints and varnishes to improve adhesion to the substrate

Benefits at a glance

Important product effects, that can be achieved by using Dynasylan® 2101 are:

improved mechanical properties, e.g. flexural strength, tensile strength, impact strength, modulus of elasticity
improved resistance to moisture and corrosion
lower tendency of colouring effects during storage compared to aminosilanes

Dynasylan® 2101 helps as well to improve processing properties such as:

better filler dispersion allowing highly-filled compound formulations
lower VOC emission compared to solvent based ureidosilanes
