        Reaction Products
        與其它產品的化學反應情況
        Silicones 硅硐膠:
              Acetoxy 乙酸基
        acetic acid 醋酸
          * 有氣味 Smell
          * 腐蝕 Corrosion
          * 化學反應 chemical reaction
              Alkoxy 烷氧基
        alcohol/methanol 酒精/甲醇
          * 抑制聚氨酯的固化 curing inhibition of Polyurethane
          * 有可能會影響某些涂漆的固化
            Slight possibility on inhibiting curing of some paint systems.
        Polyurethane 聚氨酯膠:
              Traditionally cured systems 傳統固化系統:
        * 會產生二氧化碳 formation of CO2
        * 在溫度/濕度很高/大的條件下有可能產生氣泡
          Possible bubbling risk at increasing Tempreture/Humidity.
        Skinning time
        成膜時間
        Silicones 硅硐膠:
        * 一般較短10 - 20 分鐘 Generally short 10 - 20 min.
        * 特別在濕度高時,打膠短
          Applicator can only make short runs especially at high humidity
        * 需要立即平滑 Immediate smoothening required
        Polyurethane 聚氨酯膠:
        * 施用者有更長的施工時間大約 2 - 4 小時
          2 - 4 hours longer runs / more time for applicator
        * 在高溫和高濕度的情況下, 打膠和刮平不太受影響
          Application & smoothening time less effected even at high temperature and humidity
        Resistance to solvent / gasoline
        抗溶劑及汽油
        Silicones 硅硐膠:
        * 不宜與溶劑/汽油/燃油接觸
          Not suitable in contact with solvents/ gasoline/ fuel
          溶劑的吸收性 Absorption of solvents
        * 有氣味 swelling
        * 性能的消失 loss of properties
        Polyurethane 聚氨酯膠:
        * 很好的抗溶劑侵蝕性 very good resistance to solvents
        * 可在儲存區/汽油站等地方使用 use in storage areas / gasoline stations etc.
