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(shì) 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(chǎng)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(wú)負(fù)面影響,僅是美觀問(wèn)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(méi)有以后的粘接問(wèn)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
