    1. Characteristics固化/干特性: The following chart shows the typical drying time/cure rate of white topcoat formulations based on THYON OX787. Evaluations of Gardner Circular Dry Times are very interesting. The dry times will normally lie somewhere within the area plotted on the chart below. Pot life was determined with a recording Brookfield viscometer and is defined as the time required to double the initial viscosity of approximately 250 centipoise. The pot life will normally be between 4 and 8 hours when measured by this method.
    • THYON OX787的配方做的白面漆典型的干燥时间/固化。评估“加德纳通函干燥时间”是非常有趣的 。干燥时间通常介于下面的图表上绘制的区域内。用记录Brookfield粘度计测定混合后使用时间,被测定为同一的时间内两倍初始粘度为约250厘泊。固化一般会在4小时和8小时之间时,用这种方法测量。

     

     

     

    1. Durability紫外线耐久性: Q gloss retention results were obtained using UVB-313 bulbs with 4 hours of light at 60°C followed by 4 hours of condensation at 40°C.

    QUV光泽保持率的结果表明,用UVB-313灯泡在60℃下用4个小时的光40℃下随后的4个小时的缩合

     

    Formulation Tips配方技巧

     

    » Crosslinker交联剂: For maximum gloss retention properties, aliphatic isocyanates are recommended. Also the Trimer or Biuret versions of hexamethylene diisocyanate can be used.

    A ratio of 1.05: 1 of isocyanate to hydroxyl is normally recommended in the industry.

    为了获得最大的光泽保持性,推荐使用脂肪族异氰酸酯。也可用于微调或六亚甲基二异氰酸酯缩二脲版本。工业上异氰酸酯与羟基通常建议的比率1.051

     

    » Solvent: 溶剂 Ketone solvents will give the best viscosity –VOC due to a combination of good solvency and low density. Aromatics such as xylene and toluene provide good solvency and can be readily used in combination with the more polar solvents. Glycol ether acetates can be used but normally do not provide low viscosity/VOC. PM-Acetate should be avoided due to its film retention characteristics. Avoid alcohols and glycol ethers; their hydroxyl functionality can react with the isocyanates. 

    酮类溶剂将给予最好的粘度-挥发性有机化合物,由于良好的偿付能力和低密度的组合。芳烃如二甲苯和甲苯提供了很好的溶解性和极性较大的溶剂,可以容易地组合使用。乙二醇醚乙酸酯,可以使用,但通常不提供低粘度/ VOCPM-醋酸应避免由于其膜层保留特性。避免醇及乙二醇醚,它们的羟基官能团可以与异氰酸酯反应。

    » Catalysis催化剂 : Catalysis with 0.005% dibutyltin dilaurate on total binder solids is normally recommended. Higher catalyst levels will result in shorter pot lives and faster cure rates.

    催化月桂酸二丁基锡推荐用量占总固含的0.005更高的的催化剂添加量将导致在较短反应活性和更快的固化率。
