This technology allows the coating of any surface with a highly reflective and conductive metal thin film.
TECHNOLOGY
- Coating : Coating of the substrate with a formulation made of a polymerizable resin and metal ions
- UV curing: The formation of the metal thin film is triggered by the cure of the polymer and the photo-reduction of metal ions
- Final result : The final coating appears as a bilayer film
- Top : highly conductive and reflective metal thin film
- Bottom : a composite made of polymer and metal nanoparticles
INNOVATION ADVANTAGES
- Nanoparticles free formulation
- No solvent evaporation: acrylic monomer
- Cold technology
- Reduced cost: very low content in metal thanks to the ionic-based formulation
- Broad range of available metals: Ag, Au, Cu, Pd, Pt, Al … or any mixture of
COATING PROCESS
- Suitable for spray and printing technologies: fully tunable viscosity
- Quick coating: from seconds to few minutes
- Works on any surface, including: aluminium, brass, glass, paper, plastic, stainless steel, textile, wood…
COATING
- Mirror like surface: high reflectivity
- Conductivity: preliminary shown an apparent resistivity of 1.6×10-3 Ω.m
- Anti-microbial activity: using of Ag and Cu
- Peeling resistance: tape test ok
- Hardness: pencil test ok
- Flexibility: conservation of the substrate flexibility
