Low volatility UV292 , Tinuvin 292 HALS Light Stabilizer with
Exceptional light absorbing characteristics
Quick Detail :
UV292 is an excellent general purpose liquid hindered amine light
stabilizerespecially developed for coatings . Its cost efficiency
provides significantly extended lifetime to coatings by minimizing
paint defects such as cracking and gloss loss .
- Name : UV292
- Chemical name : Bis ( 1 , 2 , 2 , 6 , 6 - pentamethyl - 4 -
piperidyl ) sebacate
- CAS No. : 41556 - 26 - 7
- Function : Low volatility , Exceptional light absorbing
characteristics and good compatibility
292 may be used after adequate testing in a broad range of
applications such as
- automotive refinish coatings
- industrial topcoats
- coil coatings
- wood stains or trade sales paints and varnishes
- radiation curable coatings
Its high cost efficiency has been demonstrated in coatings based on
a variety of
binders such as
- one - and two - component polyurethanes
- thermoplastic acrylics ( physical drying )
- thermosetting acrylics , alkyds and polyesters
- alkyds ( air drying )
- water borne acrylics
- phenolics , vinyls
- radiation curable acrylics
The weatherability of such coatings can be significantly improved
by use of a combination of UV292 with another UV absorber , e . g .
UV1130 , UV384 , or UV328 . These synergistic combinations give
automotive coatings superior protection againstgloss reduction ,
cracking , blistering , delamination and color change .
The light stabilizers may be added in two coat automotive finishes
to the base and
clearcoat . The optimum protection should be determined by
evaluating a broad range ofconcentrations.
Possible interactions of UV292 with paint ingredients such as acid
catalysts shouldbe carefully evaluated. Should a negative
interaction occur , UV123 would be recommended .
