Dynamic Viscosity at 20°C cps 400
Tinuvin 292 is miscible to more than 50% with most commonly used paint solvents at 20°C. Water
solubility is less than 0.01%.
These typical values should not be interpreted as specifications

Applications
Tinuvin 292 is recommended for applications such as:
• automotive coatings (non-acid catalyzed)
• industrial coatings
• wood stains or do-it-yourself paints
• radiation curable coatings (with no loss of cure speed)

Its high efficiency has been demonstrated in coatings based on a variety of binders such as:
• one- and two-component polyurethanes (water and solvent)
• thermoplastic acrylics (physical drying)
• thermosetting acrylics, alkyds and polyesters
• alkyds (air drying)
• waterborne acrylics
• phenolics, vinylics
• radiation curable acrylics
• exterior construction coatings (roofing, etc.)
• construction adhesives and sealants

Product Description Tinuvin 400:

is a liquid hydroxyphenyl-triazine (HPT) UV absorber designed to fulfill the high
performance and durability needs of solventborne, and 100% solids automotive and
industrial finishes. Its low color and stability make it an excellent choice for all coatings
where low color characteristics are ideal.

Key Features & Benefits:

– Hydroxyphenyl-triazine with high absorbance in the UV-B region
– Low color, low migration
– Minimal interaction with metal catalysts and amine crosslinkers
– Excellent photo-permanence

Chemical Structure:

Tinuvin 400 is a mixture of: 2-[4-[(2-Hydroxy-3-dodecyloxypropyl)oxy]-2-hydroxyphenyl]-
4,6-bis(2,4-dimethylphenyl)-1,3,5-triazine & 2-[4-[(2-Hydroxy-3-tridecyloxypropyl)oxy]-2-
hydroxyphenyl]-4,6-bis(2,4-dimethylphenyl)-1,3,5-triazine
Tinuvin 400 is an 85% solution of the active substance in 1-methoxy-2-propanol
