TINUVIN 900 is a UV absorber of the hydroxyphenylbenzotriazole
class developed specifically for coatings. It is particularly suitable for
coating systems exposed to high temperatures and/or extreme
environmental stresses. It is, therefore, especially suitable in view of
the high durability demands for high performance coating applications.
TINUVIN 900 is recommended for applications such as:
· automotive coatings
· coil coatings
· powder coatings.
TINUVIN 900 may be used in combination with a light stabilizer of the
sterically hindered amine class (HALS) such as recommended below.
These combinations give coatings superior protection against gloss
reduction, cracking, blistering, delamination and color change. The
light stabilizers may be added in two coat automotive finishes to the
base and clear coat. However, according to our experience the
optimum protection is achieved by adding the light stabilizer to the
topcoat.
The amount of TINUVIN 900 required for optimum performance should
be determined in trials covering a concentration range.
