The particular advantages of Dynasylan® HYDROSIL 2627 compared with the corresponding monomeric amino- or alkyl-functional alkoxysilanes are:
- Alcohol content of ≤ 1% guarantees nonflammability, safe handling, and minimal volatile organic constituents emission.
- No hydrolysis chemistry is needed as Dynasylan® HYDROSIL 2627 is a ready-to-use aqueous silane hydrolysate.
- Easily diluted with water to adjust to target concentration.
- Adaptable to a broad pH range.
Important product effects that can be achieved by using Dynasylan® HYDROSIL 2627 are:
- Improved mechanical properties: Flexural strength, tensile strength, impact strength, and modulus of elasticity.
- Improved resistance: To moisture and corrosion.
- Improved adhesion: Excellent surface wetting of inorganic substrates and optimal reaction with organic polymers.
Dynasylan® HYDROSIL 2627 helps improve processing properties such as:
- Nonflammability: Making almost no particular equipment safety precautions necessary.
- Better filler dispersion: Leading to increased filler content during compounding.

- Product Applications
Dynasylan® HYDROSIL 2627 is a aqueous oligomeric ami- noalkyl-functional silane hydrolysate, in which the silanol groups can be bonded to an inorganic substrate and the organophilic amino group can interact with a suitable polymer or resin.
Examples of suitable inorganic substrates are:
- Glass, glass fibers, glass beads and glass wool.
- Mineral wool.
- Metals.
- And various fillers like quartz, wollastonite or ATH.
Examples of suitable polymers and resins are:
- Thermosets like epoxy, phenolic, furanic and melaminic resins.
- Thermoplastics like PA, PBT, EVA, PPS, MAPE, MAPP, PVB, acrylates.
- Elastomere like silicones.
Dynasylan® HYDROSIL 2627 finds application in many industries. Advantages arise in water-based systems.
Examples are:
- As a glass and metal primer.
- As a size constituent of glass fiber/glass fabric composites or mineral wool insulating materials.
- As an additive to foundry resins and abrasives.
- As a pretreatment or an additive to mineral-filled thermoplastic compounds.
- As an additive for adhesives and sealants to improve adhesion to the substrate.
- As an additive and/or primer for paints and varnishes to improve adhesion to the substrate.
