|
Silicones 硅硐膠: |
Acetoxy 乙酸基 |
|
acetic acid 醋酸
* 有氣味 Smell
* 腐蝕 Corrosion
* 化學(xué)反應(yīng) 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(tǒng)固化系統(tǒng): |
|
* 會產(chǎn)生二氧化碳 formation of CO2
* 在溫度/濕度很高/大的條件下有可能產(chǎn)生氣泡
Possible bubbling risk at increasing Tempreture/Humidity. |
|
|
|
Skinning time 成膜時(shí)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(shí),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(shí)間大約 2 - 4 小時(shí) 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(qū)/汽油站等地方使用 use in storage areas / gasoline stations etc. |
