LASERSense™ Sensitizing Additives for Laser-Curable Wood Adhesive Systems

Purpose: This page documents where laser-curable wood adhesive systems are industrially viable today and how formulation and process design can support moisture resistance aligned with EN 204 D4. It focuses on sensitizing additives used by formulators to design laser-assisted curing systems. It does not describe finished adhesives and does not offer adhesive products for sale.

LASERSense™ LASER sensitizing additives are developed by Kela Materials.

Why wood and engineered timber are different

Wood and engineered timber assemblies commonly require thick bond lines, involve porous substrates, and exhibit strong optical scattering. These factors make curing less predictable: UV/visible exposure may not develop conversion through the full adhesive thickness, and oven-based processes can increase energy cost and limit cycle time.

Where NIR-assisted curing fits

NIR-assisted curing is relevant when a formulator needs rapid, localized cure development despite limited optical penetration (opacity, fillers, scattering, substrate variability). A sensitizing additive can enable controlled in-layer energy conversion under near-infrared irradiation, helping the system reach practical cure development across thick bond lines.

Safe technical mechanism statement (system-level)

Under NIR laser irradiation, this sensitizing additive may undergo certain kind of reduction alongside photothermal effects. These effects can lower the effective activation barrier of the formulation’s existing polymerization or crosslinking pathway, supporting cure development through thick adhesive layers. In this application class, curing does not rely on UV penetration, but can be achieved via NIR-assisted mechanisms depending on formulation and process conditions.

Titanium Oxynitride (TiON) Nanoparticles

Titanium Oxynitride for conductive ceramic electrodes & visible-light-active coatings

Direct Answer

Titanium oxynitride (TiON) nanoparticles are ≈65 nm rock-salt TiOₓNᵧ particles produced by low-temperature synthesis, used as a conductive and visible-light-active oxynitride phase in composite electrodes and coatings where final properties depend on the designed architecture.[web:1]

What it is

A research-grade titanium oxynitride nanopowder with nominal TiOₓNᵧ composition, typical O:N ratio near 5:1, cubic or cube-like morphology, and polycrystalline rock-salt (NaCl-type) structure, intended to function as an oxynitride component rather than a finished device.[web:1]

For R&D teams developing conductive ceramic or photo-active electrodes

What it is NOT

Not pure TiO₂ and not pure TiN; TiON is an intermediate oxynitride phase with both oxygen and nitrogen in the anion lattice. It is not an intrinsic “7× capacitance” material, not a guaranteed photocurrent source, and not a certified biomedical coating; reported electrochemical and photocatalytic metrics in the Technical Data Sheet correspond to specific composite electrodes and photoelectrodes, not to the loose powder alone.

Where it fits

TiON nanoparticles fit as a functional ceramic phase in carbon-based electrodes, oxide or oxynitride films, and polymer–ceramic composites where a TiN-related rock-salt framework combined with oxynitride band structure is required. Typical use involves mixing the powder into inks, slurries, or coating formulations that are then processed into electrodes or functional layers.

Boundary condition

Useful behavior depends on controlled synthesis, processing history, atmosphere and temperature (stability up to about 350–400 °C in air, higher in inert gas), and on adequate dispersion to avoid agglomeration; these constraints delimit the operating window and must be considered in each application design.[web:1]

EMI Shielding & Conductive Coatings | Network Percolation using SWCNT

EMI Shielding & Conductive Coatings | SWCNT Networks

Single-walled carbon nanotubes enable EMI shielding by forming a percolated conductive network that supports induced surface currents and impedance loss across a broad frequency range.

Direct Answer

SWCNT enables EMI shielding by forming a continuous conductive pathway at low loading, allowing electromagnetic energy to be dissipated through network conduction rather than bulk absorption. Shielding efficiency depends on network continuity, junction resistance, and coating microstructure.

In conductive coatings, SWCNT forms a high-aspect-ratio network that reduces percolation threshold and enables thin-film EMI attenuation. Performance is sensitive to dispersion quality and inter-tube junction resistance.

LASERSense™ Sensitizing Additives for Laser-Assisted Adhesive Curing

Laser-assisted Curing of Adhesives|Photothermal Effect to Cure Resin using BCHP

LASERSense™ Laser-curable adhesive systems are developed by Kela Materials and are formulation-and-process designs that use UV, visible, or near-infrared (NIR) irradiation to develop polymerization or crosslinking within an adhesive bond line. They may combine photochemical and photothermal effects to address thick, opaque, or filled layers where penetration is limited. Durability expectations are application-specific and must be validated by system testing.

Purpose: This page explains sensitizing additives used by adhesive formulators to design laser-assisted curing systems. It does not describe finished adhesives and does not offer adhesive products for sale.

System explanation (formulator level)

Why UV/visible alone can fail in thick or optically challenging systems

  • Limited penetration: Thick bond lines, pigments, fillers, and scattering reduce effective light depth.
  • Surface-first conversion risk: Fast surface conversion can leave incomplete cure deeper in the layer.
  • Process sensitivity: Small changes in thickness, substrate reflectance, or fixture geometry destabilize cure consistency.

Why NIR photothermal sensitization matters

NIR is relevant when a formulator needs cure development beyond what UV/visible penetration can reliably deliver. A sensitizing additive can enable controlled in-layer energy conversion under NIR irradiation, which can allow stable cure development in thick, opaque, or filled systems. It does not replace cure chemistry; it makes possible a practical laser-assisted process window.

Role of the sensitizing additive (safe mechanism statement)

At a system level, the sensitizing additive functions as a controlled energy-conversion component (often photothermal, sometimes combined with activation effects), supporting the formulation’s existing polymerization or crosslinking pathway. Performance depends on resin chemistry, additive compatibility, irradiation conditions, and joint design.

What this page is / is not

  • Is: A formulator-facing hub page for designing laser-curable adhesive systems using sensitizing additives.
  • Is not: A finished adhesive product page. This page does not sell adhesives.

Comparison table

Dimension UV curing NIR laser-assisted curing (with sensitizing additives) Thermal / oven curing
Best fit Thin, optically clear layers; good exposure access Thick / opaque / filled layers; localized processing Bulk heating acceptable; large thermal mass
Main limitation Penetration limits in scattering/opaque systems Requires stable irradiation + compatible formulation Energy cost; slower cycle; heat impact on substrates

LaserMark-G™ (ZrN) — Laser Marking Additive for Glass

What LaserMark-G™ (ZrN) does

LaserMark-G™ is a zirconium nitride (ZrN) based marking additive designed to help glass surfaces develop visible contrast under laser irradiation. It is used by formulators and process engineers to build stable, production-ready marking systems for glass parts where direct laser marking is required.

Why glass is difficult to mark

Glass is optically transparent across much of the visible range and has low absorption at many process wavelengths. As a result, the laser energy may pass through or distribute without producing a controlled surface change. In addition, smooth glass surfaces provide limited anchoring points, so any mark that relies on deposited material must also pass adhesion and abrasion requirements.

How ZrN contributes (system-level mechanism)

  • Energy coupling: ZrN provides stronger laser energy coupling than bare glass, enabling a localized surface transformation.
  • Micro-contrast formation: Under appropriate conditions, controlled micro-roughening / micro-structuring can increase scattering and perceived darkness.
  • Process window stabilization: In coating / ink systems, ZrN can help reduce sensitivity to minor changes in focus, speed, and power by improving local absorption.

Typical use formats

  • Coating / ink route: ZrN dispersed in an inorganic/organic binder system (often with silane coupling strategy) then laser-written.
  • Direct surface treatment route: ZrN-containing layer applied by spray/print/transfer, followed by laser exposure and optional post-cleaning.

What to optimize first

  • Laser wavelength and pulse regime (fiber 1064 nm, green 532 nm, UV 355/405 nm, CO₂ 10.6 μm)
  • Coating thickness / loading and dispersion quality (agglomerates reduce consistency)
  • Binder selection for adhesion + thermal shock resistance (soda-lime vs borosilicate vs tempered glass)
  • Post-treatment requirements (wash, abrasion, chemical resistance)

Note: Mark appearance and durability depend on the complete system (glass type, laser, binder, dispersion, thickness). LaserMark-G™ is supplied as an additive material, not a finished marking ink.
