Product Benefits

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.

Storage & Handling

Storage Conditions
  • It is recommended to store Dynasylan® HYDROSIL 2627 above 4°C.
  • Singular freezing does not influence the product quality.
  • Frozen product is re-useable after complete thawing and homogenization. Stirring is sufficient for homogenization.
  • Dynasylan® HYDROSIL 2627 has a flash point ≥ 95°C.
  • It can be stored and transported advantageously according to different local requirements, compared to flammable liquids (Category 2, 3, and 4), as most established monomeric alkoxysilane materials.
  • Dynasylan® HYDROSIL 2627 has a shelf life of a minimum of 12 months from delivery in an originally sealed can, drum, or IB.
