TINUVIN 123 is a new liquid HALS stabilizer based on an aminoether
functionality. Its low basicity prevents possible interactions with acidic
paint ingredients such as catalysts. Its efficiency provides significant
improvement in coatings performance by minimizing paint defects such
as cracking and gloss reduction for clear coats as well as chalking for
pigmented paints.

TINUVIN 123 is recommended for applications such as:
· automotive and industrial coatings
· decorative paints and wood stains or varnishes
TINUVIN 123 has been developed especially for high solids, acid
catalyzed automotive and industrial coatings, i.e. two coat metallic
thermosetting acrylate systems or one coat opaque thermosetting
acrylate and polyester coatings. Its high efficiency has been
demonstrated in a variety of other binders and applications such as:
· alkyd/acrylic air drying automotive refinish paints
· alkyd oxidative drying paints and varnishes
· two pack non-isocyanate coating technologies
The liquid form of TINUVIN 123 also enables easy emulsification into
water-borne systems.
The performance of TINUVIN 123 can be significantly improved when
used in combination with a UV absorber.
In Automotive coatings, combinations of TINUVIN 123 with the UV
absorbers TINUVIN 384, TINUVIN 1130, TINUVIN 928, or TINUVIN
400 will significantly improve the weathering resistance and provide
superior protection against gloss reduction, cracking, colour change,
blistering and delamination. The light stabilizers may be added in two
coat applications to both the base and the clear coat.
In wood coatings, combinations of TINUVIN 123 with the UV absorbers
TINUVIN 384 or TINUVIN 1130 have been found highly effective in air
drying alkyd based formulations. The light stabilizer blends can be
added to film forming finishes as well as decorative penetrating stains.
The amount of TINUVIN 123 required for optimum performance should
be determined in trials covering a concentration range.
Liquid HALS stabilizer based on an aminoether functionality. Its low basicity prevents possible interactions with acidic paint ingredients such as catalysts. Its efficiency provides significant improvement in coatings performance by minimizing paint defects such as cracking and gloss reduction for clear coats as well as chalking for pigmented paints. Miscible to more than 50% with most commonly used paint solvents. Water solubility is less than 0.01%. Recommended for automotive and industrial coatings, decorative paints and wood stains or varnishes.
