light Stabiliser ( Tinuvin292- Tinuvin 328 – Tinuvin 1130 )
292 is a general-purpose liquid hindered-amine light stabilizer (HALS)
especially developed for incorporation with a wide variety of paint
systems, offering extended protection to coatings when used in the
efficiency of TINUVIN 292 provides significantly extended lifetime to
coatings by minimizing paint defects such as cracking and loss of gloss
for clear coats and reducing chalking of solid shade coatings.
Ciba® TINUVIN® 328 UV absorber
TINUVIN® 328 is a solid UV absorber of the
class, specifically developed for coatings. Due to its broad UV
absorption, TINUVIN 328 provides efficient protection to coatings and
light-sensitive substrates such as wood and plastics.
is soluble in most common solvents. It can be used in combination with
a light stabilizer of the sterically-hindered amine or aminoether class
(HALS) to give coatings superior protection against gloss reduction,
cracking, blistering, delamination and color change.
relative low heat resistance of TINUVIN 328 makes it unsuitable for
coatings cured at temperatures above 100°C, the product is only
recommended for ambient and low temperature cured systems, i.e.
air-drying alkyd-based systems. For further information please click

1130 is a liquid UV absorber of the hydroxyphenylbenzotriazole class
specifically developed for coatings. The product is miscible with most
common solvents but also easily incorporated into waterborne systems.
The high temperature and extraction resistance of TINUVIN 1130 makes it
especially suitable for wood, general industrial and automotive
coatings. Because of its broad UV absorption, TINUVIN 1130 provides
efficient protection to light-sensitive substrates such as wood and
