Application应用
· A smooth surface is obtained by sand the wood with #150-320 grit sandpaper.
· 用# 150 - 320砂纸把木头的表面打磨光滑。
· After applying a first coating, wait until it gets dried. Then sand the applied wood using #320 grit sandpaper.
· 油完第一层后，等到它变干。然后再使用# 320砂纸打磨。
· A second coat is applied and the wood is left for two weeks driying before performing the quality tests.
· 油完第二层后，放置2周后测试其品质性能。

Formulation Tips 配方提示
»Coalescent（成膜助剂）: THYOSIL E1549 could be used at normal temperatures with the addition of coalescing solvents. The selection of an optimum coalescing system depends on the required drying rate, temperature and relative humidity. It is usually recommended 30% of coalescing solvents but it may be used lower levels depending on the porosity of the substrate, the type of application equipment, moisture conditions and co-solvents used in the formulation. Reducing the amount of coalescent allows faster drying but an excessive reduction may result in poorer film formation and consequently the loss of the stain resistance. Various types of coalescing may be used. It must be determined for each application.
It is recommended to allow the formulations equilibrating for at least 8 hours after addition of coalescing agents to obtain consistency results in the tests performed.
THYOSIL E1549 可以在常温下可以与溶剂混合，根据所需要的干燥速度,温度和湿度，选择最佳的配比。可以在常温下可以添加成膜助剂，根据所需要的干燥速度,温度和湿度，选择最佳的配比。通常推荐使用 30%的成膜助剂（与配方中E1549的固含量相比），也可以低于或高于此水平，取决于基材的具体特性，所使用的设备，水分含量等条件。减少成膜助剂的使用干燥速度会快，但若添加太少会影响成膜性，同时还会减少防污性能。可以使用各种成膜助剂，它必须适合所需要的应用，添加的成膜助剂要8小时前后测试结果没有变化。
»Rheology Modifiers: 流变改性剂We suggest the use of associative thickeners. Keep in mind that the efficiency of urethane associative thickeners depends largely on the selection of coalescing adopted
我们推荐使用缔合型增稠剂，记住聚氨酯缔合增稠剂的效果取决于成膜助剂的选择。
»Antifoam:消泡剂Antifoam should be tested in each case. Care must be taken with the concentration chosen as an excess of antifoaming can cause fish eyes defects or loss of transparency of the film.
