Silanes improve adhesion to glass, metals, ceramics, and plastics, while increasing chemical and thermal resistance.
Q-SIL
Q-SIL offers a broad portfolio of organofunctional silanes engineered for precise surface treatment, bonding, modification, and moisture control. These high-performance compounds act as coupling agents, crosslinkers, adhesion promoters, and hydrophobing agents across a wide range of technical applications
Smart silanes for demanding applications
Q-SIL silanes feature dual-functionality: an organic end group tailored to the resin system and a reactive alkoxy group for bonding to inorganic surfaces. This makes them ideal as coupling agents, surface modifiers, and adhesion promoters. Whether improving pigment wetting, reinforcing filler bonds, or enhancing moisture resistance, Q-SIL delivers performance where it counts – at the interface.
Where Q-SIL works best
Adhesives & Sealants
Paints, Coatings & Colours
Enhances pigment wetting, adhesion, water resistance, and durability. Particularly effective for primers, anti-corrosion coatings, and hydrophobic surfaces.
Plastics & Rubber
Improves compatibility between fillers and polymers (thermoplastics, thermosets, elastomers) and acts as a crosslinking agent in silane-modified polyolefins.
Construction Materials
Used in concrete additives, waterproofing systems, and bonding enhancers for construction sealants and adhesives.
Electronics & Casting
Q-SIL silanes improve flow, curing, and electrical resistance in casting resins and encapsulants.
Q-SIL product highlights
Silanes in the Q-SIL range are defined by their dual reactivity: an organic functional group that interacts with resin systems, and alkoxy groups that bond with inorganic substrates like glass, minerals, and metals. This makes them highly effective as coupling agents, crosslinkers, surface modifiers, and adhesion promoters across a wide range of industrial applications. Below is a selection of representative Q-SIL grades, illustrating the diversity of functionalities and use cases within our portfolio. Download out brochure for a full overview of available silanes.
