          Paintability
          可涂性
          Silicones 硅硐膠:
          * 一般來說不能涂漆 Not paintable in general
          * 填硅硐膠的接縫兩側涂漆也能影響膠的粘接性
            Risk of adhesion problem of paint next to Silicone joint
          * 修補難 Critical in repair / maintenance situations
          Polyurethane 聚氨酯膠:
          * check compatibility 可以在上面涂漆 Paintability o.k. in general
          * 易修補 Easy also in maintenance situations
          Difficult to repair
          難于修補
          Silicones 硅硐膠:
          * 硅硐膠與硅硐膠之間很難粘接
          Adhesion Silicone to Silicone difficult
          * 難于清潔/如果基面用過硅硐膠,在第二次使用時,應將基面徹底清潔干凈才能達到良好粘結效果
          Very difficult to clean / prepare a substrate properly to get a good adhesion when Silicone has been used before
          Polyurethane 聚氨酯膠:
          * 易修補,因為新舊聚氨酯膠之間有非常好的粘結性
          Easy to repair because excellent adhesion of fresh on cured Polyurethane
          * 只要有個V形切口就足夠了,無需將舊的聚氨酯膠完全清除
          V cut is sufficient no full removal of old Polyurethane necessary
          Shelf life
          保質期
          Silicones 硅硐膠:
          * 在酸性系統中有良好作用 Very good for acetoxy systems
          * 容易施用,無需完全固化
          Critical for alkoxy products easy to apply by no more (full) curing
          * 早期移動裂縫的風險risk of early movement cracks
          * 施用者不易意識到保質期限
          shelf life limit cannot be realized by applicatior
          Polyurethane 聚氨酯膠:
          * 在正常包裝及儲存下的保質性能好
          Shelf life in general good in proper packaging and storage
          * 過期后產品會增加厚度,接近保質期時產品的擠出性能差
          Products get thicker over time, more difficult to extrude near shelf life limit
          * 只要產品能擠出,它會正常固化
          As long as product can be applied it will cure properly
