                      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
