LIGNOSTAB 1198 can be used to prevent natural, light-shade wood substrates from yellowing and darkening when exposed to diffused or direct sunlight. It protects wood by inhibiting the photooxidation of lignin and acts by simple aqueous pretreatment of the substrate. For tinted wood, it can be used directly within aqueous or hydro-alcoholic tinting solutions or stains. Synergistic and durable protection effects against wood discoloration and degradation are obtained when it is associated with a UV absorber. The latter can be used in the pretreatment or stain itself or preferably in a subsequently applied topcoat. With this photo-protection concept, attained wood color stabilities and improved coating durability can be achieved. The protection degree may depend on the wood species and for tinted wood on the type and saturation of the colorant. Applications that can benefit from LIGNOSTAB 1198 include indoor parquetry and furniture as well as outdoor wood and timber work (doors, windows, cladding, paneling, fencing, decking, shingles, beams, etc.)
