Palmer Holland - Dynasylan HYDROSIL 1151

Dynasylan® HYDROSIL 1151 can be applied advantageously in water-based binder systems or for substrate pretreatment. It can also be used as a constituent of aqueous sizes or as an additive.

Product Applications

Dynasylan® HYDROSIL 1151 is an important additive in many applications. Particular advantages arise in water-based systems.

Examples:

Glass fiber/glass fabric composites: as size constituent or finish
Glass and metal primers
Mineral fiber insulating materials, abrasives: as additive to phenolic resin binders
Foundry resins: as an additive to cold-curing phenolic and furan resins
Sealants and adhesives: as primer or additive mineral-filled composites for pretreatment of fillers and pigments or as additive
Paints and coatings: as additive and primer for improving adhesion to the substrate
The most important effects achieved using Dynasylan® HYDROSIL 1151 are:

Improvement in product properties, such as:

Mechanical properties (flexural strength, tensile strength, impact strength, and modulus of elasticity)
Moisture and corrosion resistance

Improvement in processing properties, such as:

Adhesion
Better filler dispersion
High flash point

Product Reactivity

Dynasylan® HYDROSIL 1151 is a bifunctional organic compound in which the functional silanol groups can bond to an inorganic substrate; the organophilic amino group can interact with a suitable polymer.
The advantage of Dynasylan® HYDROSIL 1151 compared to other amino-functional alkoxysilanes is its non-flammability, and no volatile organic constituents are released.
It can be diluted with water in all proportions and the hydrolysates are long-term stable.

Examples of suitable inorganic substrates: Glass, glass fibers, mineral wool, silica acid, quartz, sand, cristobalite, wollastonite and mica; also suitable are aluminum trihydroxide, kaolin, talc, other silicate fillers, metal oxides and metals.
Examples of suitable polymers: Epoxy resins, polyurethane, phenolic resins, furan resins, melamine resins, PA, PBT, PC, EVA, PP, PVAC, acrylates, and silicone.
