UV Resistance 防紫外线性能 |
|
Silicones 硅硐胶: |
|
* 良好的防紫外线性能(非填冲产品外)
Generally good resistance (Inorganic system if not extended)
* 会有变黄的趋势 Tendency to yellow especially
* 透明 Transparent
* 填冲产品,低成本 extended products / low cost
* 因为硅硐接缝容易很快变脏,对于很多场所都不苛求
Not too critical in any case because Silicone joints get dirty quickly |
|
|
Polyurethane 聚氨酯胶: |
|
* 质量好的产品有良好的防紫外线性能
Quality products good resistance
* 表面有可能”橙皮”或龟裂(依配方而定)仅是表面影响而已
Tendency to slight“orange peel”effect / surface cracks depending on formulation
* 对粘合的性能无负面影响,仅是美观问题而已
surface effect only no negative influence on function or performance of the sealant aesthetic issue only

Cleaning / dirt pick up 自清洁与受尘性 |
|
|
Silicones 硅硐胶: |
|
* 刚施用时即使用溶剂都很难清洁,具污染性
Fresh difficult to clean even with solvents stains
* 固化后的硅硐胶很难完全剥离会留下残余,不易与其他产品粘合
Cured Silicone difficult to get off completely (always silicon residue) nothing else sticks
* 硅硐胶极易受尘,因静电作用使接缝处变黑
Silicones pick up dirt easily electrostatic load joint turns black |
|
|
Polyurethane 聚氨酯胶: |
|
* 刚施用时,易用溶剂清洁干净 Fresh is easy to clean with solvent
* 固化的聚氨酯胶易机械剥除,不留残余,没有以后的粘接问题
Cured PU easy to remove mechanically without leaving residue.No problem for Later adhesion
* 不易受尘 Little to no dirt pick up
