        UV Resistance 防紫外线性能

        Silicones 硅硐胶:
        * 良好的防紫外线性能(非填冲产品外)
          Generally good resistance (Inorganic system if not extended)
        * 会有变黄的趋势 Tendency to yellow especially
        * 透明 Transparent
        * 填冲产品,低成本 extended products / low cost
        * 因为硅硐接缝容易很快变脏,对于很多场所都不苛求
          Not too critical in any case because Silicone joints get dirty quickly
        Polyurethane 聚氨酯胶:
        * 质量好的产品有良好的防紫外线性能
          Quality products good resistance
        * 表面有可能”橙皮”或龟裂(依配方而定)仅是表面影响而已
          Tendency to slight“orange peel”effect / surface cracks depending on formulation
        * 对粘合的性能无负面影响,仅是美观问题而已
          surface effect only no negative influence on function or performance of the sealant aesthetic
          issue only
        Cleaning / dirt pick up
        自清洁与受尘性
        Silicones 硅硐胶:
        * 刚施用时即使用溶剂都很难清洁,具污染性
          Fresh difficult to clean even with solvents stains
        * 固化后的硅硐胶很难完全剥离会留下残余,不易与其他产品粘合
          Cured Silicone difficult to get off completely (always silicon residue) nothing else sticks
        * 硅硐胶极易受尘,因静电作用使接缝处变黑
          Silicones pick up dirt easily electrostatic load joint turns black
        Polyurethane 聚氨酯胶:
        * 刚施用时,易用溶剂清洁干净 Fresh is easy to clean with solvent
        * 固化的聚氨酯胶易机械剥除,不留残余,没有以后的粘接问题
          Cured PU easy to remove mechanically without leaving residue.No problem for Later adhesion
        * 不易受尘 Little to no dirt pick up
