The particular advantages of Dynasylan® HYDROSIL 2926 compared with the corresponding monomeric epoxyfunctional alkoxysilanes are:
- Alcohol content of ≤ 1% guarantees nonflammability, safe handling, and minimal volatile organic constituents emission.
- No hydrolysis chemistry is needed as Dynasylan® HYDROSIL 2926 is a ready-to-use aqueous silane hydrolysate.
- Easily diluted with water to adjust to target concentration.
- Adaptable in a broad pH range.
Important product effects that can be achieved by using Dynasylan® HYDROSIL 2926 are:
- Improved mechanical properties, e.g. flexural strength, tensile strength, impact strength, modulus of elasticity.
- Improved resistance to moisture and corrosion.
- Improved adhesion by excellent surface wetting of inorganic substrates and optimal reaction with organic polymers.
Dynasylan® HYDROSIL 2926 helps as well to 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 2926 is a bifunctional organic compound in which the silanol groups can be bonded to an inorganic substrate and the organophilic diol-functional 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 or resins are:
- Thermosets like epoxy, phenolic, furanic and melaminic resins.
- Thermoplastics like PA, PBT, EVA, PPS, MAPE, MAPP, PVB, acrylates.
- Elastomers like silicones.
Dynasylan® HYDROSIL 2926 finds application in the products of 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 2926 above 4°C.
- However, singular freezing does not influence the product quality.
- Frozen product is re-useable after complete thawing and homogenization. Just stirring is sufficient for homogenization.
- Dynasylan® HYDROSIL 2926 has a flash point > 93°C and can be stored and transported accordingly with different local requirements, compared to flammable liquids (Category 2, 3, and 4), as with the most established monomeric alkoxysilane materials are.
- Dynasylan® HYDROSIL 2926 has a shelf life of minimum 12 months from delivery in an originally sealed can, drum or IBC.
