Our technologies
Patented surface photochemistry — covalent adhesion, direct to the substrate.
Photoactivated surface reactions
Our patented technologies use controlled photo-activation to create covalent bonds directly between coatings and difficult substrates. When a UV photon of the right wavelength reaches the surface, it activates a specific molecule in our primer or activator system, triggering an instant surface reaction that forms a durable, covalently anchored interface.
There are no complicated chemical chain reactions to manage. No sensitivity to humidity, temperature, or other environmental variables. As long as a photon of the correct wavelength reaches the surface, bonding occurs — consistently, repeatably. It’s just physics.
This makes our products both robust and remarkably simple to use. Where traditional adhesion promoters depend on delicate surface-energy matching or expensive functional oligomers, Duoprime® relies on well-defined photochemistry that delivers the same result every time. Built for the substrates that are hard to coat — melamine, PET and PP — it works just as well on easier ones like PMMA and PVC.
An activator or primer, formulated for the substrate, applied thin on standard line equipment.
Light of a specific wavelength triggers a surface reaction — covalent bonds form directly into the substrate.
The next coating or print bonds covalently to the activated surface.
Tuned to each substrate
Every Duoprime® product works the same way at the interface: a thin layer, UV light of a specific wavelength, and covalent bonds formed directly into the substrate.
Converts the inert melamine surface into acrylate-reactive sites. The next UV coat co-cures into one monolithic, covalently bonded layer — no soft primer layer to protect, so coatings can be thinner and harder.
Instant covalent adhesion on untreated PET. The activator forms a hard sub-micrometre film bonded to both the PET and the next layer, so foils bend at very small radii without delaminating — on lower-cost foil, with harder top coats and no corona or TCA treatment that loses effect over time.
Covalent adhesion to PP without isocyanates. A drop-in 1K primer that supports harder, stiffer top coats — or a single one-layer matte coating that makes PP as easy to coat as ABS.
