Lignin-Based Flame-Retardant Coating for Wood Surfaces

European Coatings reported on 8 September 2026 on SALG-PR, a lignin-derived phenolic resin investigated by Tan and colleagues. The research explores adhesion and flame retardancy for wood. It is a laboratory development, not a newly available furniture finish.

The report describes a UL-94 V-0 result for the resin, wood adhesion of 3.78 MPa, and coated wood specimens resisting burn-through during a 300-second torch test. These results apply to the tested specimens and do not certify an entire furniture item or architectural panel.

The formulation is described as formaldehyde-free, but the reported thermal analysis detected trace formaldehyde emissions. This should not be interpreted as zero emissions under all conditions. No Turkish availability or commercial warranty is announced in the cited coverage.

MKK® Sector Assessment

For architectural surfaces, the practical question is how a coating works within a complete system. A substrate, adhesive, decorative finish and protective film may each have different properties. Evidence for one component cannot automatically establish the performance of the complete assembly.

If such resins become commercial finishes, film adhesion, appearance, care and removal would need separate evaluation. The research does not establish compatibility with TPU protective films or demonstrate scratch resistance. Its relevance is as a research direction for multifunctional wood finishes.
