Key Properties and Applications

Alkaline hindered amine free radical scavenger for waterborne coatings

Tinuvin®292

Hindered amine free radical scavenger

liquid

509/370

Basic hindered amine free-radical scavenger for many purposes; may require co-solvents when used in waterborne coatings; may interact with sensitive dispersion binders

Tinuvin®292 HP

Hindered amine free radical scavenger

liquid

509/370

Multipurpose hindered amine free radical scavenger for color-sensitive applications such as refinish coatings; may require co-solvents when used in waterborne coatings; may interact with sensitive dispersion binders

Non-alkaline hindered amine free radical scavenger for waterborne coatings

Tinuvin® 123-DW (N)

Hindered amine free radical scavenger

Liquid, 30% Active Ingredient

on-basic hindered amine free radical scavenger for aqueous formulations; no interaction with sensitive dispersions
