耐高温涂料用光稳定剂---欧稳德

欧稳德LS-123是液体氨基醚类新型受阻胺类稳定剂。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。能有效地提高清漆的寿命，减少缺陷如防止清漆龟裂和光泽消失，也可以防止色漆粉化。

OMNISTAB LS-123 is a new type of hindered amine stabilizer for liquid amino ethers. The product has a low alkalinity and minimizes the reaction with acidic components in the coating. It can effectively improve the life of varnish as well as reduce defects, such as preventing varnish cracking and gloss disappearing. What’s more, it can also prevent paint from pulverizing.

欧稳德LS-123推荐应用领域：汽车涂料、工业涂料、装饰涂料、木器涂料和清漆。是特别开发用于高固含量、酸催化汽车涂料和工业涂料，如双涂层金属热固性丙烯酸体金属闪光体系或单层热固性丙烯酸清漆和聚酯体系。

Here are some recommended applications for OMNISTAB LS-123: automotive coatings, industrial coatings, decorative coatings, wood coatings and varnishes. It is specially developed for high solids, acid catalyzed automotive coatings and industrial coatings such as double coated metal thermoset acrylate metal flash systems or single layer thermoset acrylic varnishes and polyester systems.

其优异性能在以下应用中得以体现：

醇酸树脂/丙烯酸酯气干型汽车修补漆；

氧化型醇酸漆和清漆；

双组分非异氰酸酯涂料。

Its superior performance is reflected in the following applications:

The refinish for alkyd/acrylate air-drying automotive.

Oxidized alkyd paint and varnish.

Two-component non-isocyanate coating.

此外，液态的欧稳德LS-123在水性涂料体系中很容易乳化，也可用于各种水性涂料。

In addition, the liquid OMNISTAB LS-123is easily emulsified in waterborne coating systems so that can also be used in a variety of waterborne coatings.

欧稳德LS-123 与紫外线吸收剂配合使用效果更加显著。

OMNISTAB LS-123 works more effectively with UV absorbers.

在汽车涂料应用中，欧稳德LS-123与欧稳德系列紫外线吸收剂UV-384、UV-1130、UV-928或UV-400配合使用能显著提高涂料的耐候性和有效防止光泽消失、龟裂、颜色改变、气泡和脱层。在双涂层涂料体系中，光稳定剂可用于底漆和面漆中。

In automotive coating applications, with the combination of OMNISTAB LS-123 and OMNISTAB UV absorbers, such as UV-384,UV-1130, UV-928 or UV-400, the weather ability of the coating is significantly improved. Besides, it also effectively prevents the gloss from disappearing,cracking, color changes, bubbles and delamination. In two-coat coating systems,light stabilizers can be used in primers and topcoats.

在木器涂料应用中，欧稳德LS-123与紫外光吸收剂UV-384或UV-1130配合使用对于气干型醇酸漆有很好的保护作用。光稳定剂混合物可以添加到成膜漆和装饰色漆。

In wood coating applications, OMNISTABLS-123 is used in combination with UV absorber UV-384 or UV-1130 for air-drying alkyd paint. The light stabilizer mixture can be added to the film forming lacquer and decorative paint.

建议用量(相对于树脂固体份):

汽车漆和工业漆：

0.5-2.0%欧稳德LS-123 + 1.0-3.0% 欧稳德UV-1130或UV-384或UV-928或UV-400

装饰漆和木器漆：

0.5-2.0%欧稳德LS-123(单独使用)或+ 1.0-3.0% 欧稳德UV-1130或UV-384

Recommended dosage (relative to resin solids):

Automotive paint and industrial paint:

0.5-2.0% OMNISTAB LS-123 + 1.0-3.0%OMNISTAB UV-1130 or UV-384 or UV-928 or UV-400

Decorative paint and wood lacquer:

0.5-2.0% OMNISTAB LS-123(use alone) or+ 1.0-3.0% OMNISTAB UV-1130 or UV-384

欧稳德LS-123达到最理想效果的最佳用量应根据实验结果选定。

The optimum amount of OMNISTAB LS-123 to achieve the best results should be selected according to the experimental results.
