Tiansorb 384-2 |
General: |
Tiansorb 384-2 is a liquid UV absorber of the hydroxyphenylbenzotriazole class developed for coatings. Its very high thermal stability and environmental permanence makes it suitable for coatings exposed to high bake cycles and/or extreme enviromnental conditions.
It has been designed to fulfill the high performance and durability requirements of automotive and industrial high quality finishes. Its broad UV absorption allows efficient protection of light sensitive base coats or substrates such as wood and plastics. |

Appearance: |
pale yellow liquid |
Applications: |
Tiansorb 384-2 is recommended for:
automotive coatings
general industrial applications, i.e. coil coatings, wood coatings.
The liquid form of Tiansorb 384-2 provides easy incorporation into water borne systems. The performance provided by Tiansorb 384-2 can be enhanced when used in combination with a HALS stabilizer such as Tiansorb 292 or Tiansorb 123. These combinations improve the durability of clear coats by inhibiting or retarding the occurrence of failures such as gloss reduction, cracking, color change, blistering and delamination.
The amount of Tiansorb 384-2 required for optimum performance should be determined in trials covering a concentration range. |
Recommended concentrations : |
(Concentration of stabilizer based on % weight of binder solids)
1.0 - 3.0 % Tiansorb 384-2
+ 0.5 - 2.0 % Tiansorb 123 or Tiansorb 292 |
