TINUVIN® 99’s very high thermal stability and environmental permanence makes it suitable for coatings that are exposed to high bake cycles and/or extreme environmental conditions. Its broad UV absorption allows efficient protection of light sensitive substrates, especially wood.

TINUVIN® 99 is recommended for applications such as:

• Trade sales paints, stains, and finishes for wood
• General industrial applications

The performance provided by TINUVIN® 99 can be enhanced when used in combination with a HALS stabilizer such as TINUVIN® 292 or TINUVIN® 123. These combinations improve durability by inhibiting or retarding the occurrence of failures such as gloss reduction, cracking, color change, blistering, and delamination.
The amount of TINUVIN® 99 required for optimum performance should be determined in trials covering a concentration range.
