UV Resistance 防紫外線性能 |
|
| Silicones 硅硐膠： |
|
* 良好的防紫外線性能（非填沖產(chǎn)品外）
Generally good resistance (Inorganic system if not extended)
* 會(huì)有變黃的趨勢 Tendency to yellow especially
* 透明 Transparent
* 填沖產(chǎn)品，低成本 extended products / low cost
* 因?yàn)楣桧辖涌p容易很快變臟，對(duì)于很多場所都不苛求
Not too critical in any case because Silicone joints get dirty quickly |
|
|
| Polyurethane 聚氨酯膠： |
|
* 質(zhì)量好的產(chǎn)品有良好的防紫外線性能
Quality products good resistance
* 表面有可能”橙皮”或龜裂（依配方而定）僅是表面影響而已
Tendency to slight“orange peel”effect / surface cracks depending on formulation
* 對(duì)粘合的性能無負(fù)面影響，僅是美觀問題而已
surface effect only no negative influence on function or performance of the sealant aesthetic
issue only

Cleaning / dirt pick up
自清潔與受塵性 |
|
|
| Silicones 硅硐膠： |
|
* 剛施用時(shí)即使用溶劑都很難清潔，具污染性
Fresh difficult to clean even with solvents stains
* 固化后的硅硐膠很難完全剝離會(huì)留下殘余，不易與其他產(chǎn)品粘合
Cured Silicone difficult to get off completely （always silicon residue) nothing else sticks
* 硅硐膠極易受塵，因靜電作用使接縫處變黑
Silicones pick up dirt easily electrostatic load joint turns black |
|
|
| Polyurethane 聚氨酯膠： |
|
* 剛施用時(shí)，易用溶劑清潔干凈 Fresh is easy to clean with solvent
* 固化的聚氨酯膠易機(jī)械剝除，不留殘余，沒有以后的粘接問題
Cured PU easy to remove mechanically without leaving residue.No problem for Later adhesion
* 不易受塵 Little to no dirt pick up
