天来稳(TINUVIN) 123 光稳定剂
概述:
天来稳 123 是一种用于涂料工业的含有氨基醚基团的液体受阻胺光稳定剂. 该产品具
有较低的碱性，能最大程度地避免和涂料中的酸性成分反应。天来稳 123能有效防止
开裂、失光、粉化等漆病，从而提高涂层的使用寿命。
物理特性：
外观 清澈，淡黄色液体.
20oC时动力学黏度3000mPa.s
200C 密度 0.97g/cm3
200C溶解度（g/100g溶剂）
天来稳 123能与大多数涂料用溶剂以大于50%的比例混溶，在水中的溶
解度小于0.01% ,但天来稳 123 很容易乳化进水性体系中。
应用:
天来稳 123可用于如下领域：
-- 汽车涂料和工业涂料
-- 装饰涂料和木器涂料
天来稳 123特别适用于高固体份，酸固化汽车漆和工业漆中，如： 双涂层热固丙烯酸
体系和单涂层热固丙烯酸和聚酯实色漆中。同该产品亦可用于如下涂料体系中：
·醇酸/丙烯酸类空气固化汽车修补漆
·醇酸氧气固化漆
·双组份非异氰酸酯类涂料
在汽车涂料中，若将天来稳123与紫外线吸收剂天来稳1130, 天来稳928,天来稳 384
或天来稳400配合使用, 会使涂料的耐候性有明显的提高. 协同作用会使涂料更好地发
挥作用, 对于失光、开裂、起泡、脱落和变色均有很好的抑制作用. 光稳定剂可加于
双涂层体系的清漆或中涂中。
在木器涂料中，天来稳 123与紫外线吸收剂天来稳1130或天来稳 384配合使用，对于
提高空气固化醇酸涂料的抗老化性能有极大的作用。混合后的光稳定剂可加于面漆和
渗透底漆中。
建议用量（相对于树脂固体份）:
汽车漆和工业漆： 0.5-2% 天来稳 123
+ 1-3% 天来稳 1130或天来稳 384
或天来稳 928或天来稳 400
装饰漆和木器漆 0.5-2% 天来稳 123 （单独使用）
或+ 1-3% 天来稳 1130或天来稳 384
具体用量应以实际实验效果为准

General 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.

Average molecular weight: 737 CAS No. 129757-67-1
Physical Properties Appearance : clear, slightly yellow liquid
Dynamic Viscosity at 20°C: 2900-3100 mPa s-1
Density at 20°C: 0.97 g/cm3
Miscibility (g/100 g solution) at 20°C:
TINUVIN 123 is miscible to more than 50% with most commonly used
paint solvents. Water solubility is less than 0.01%.
Application 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.
