丙烯填縫劑與矽膠的對比
特性 | 丙烯填縫劑 (Acrylic Caulk/Gap Filler) | 矽膠 (Silicone Sealant) |
---|---|---|
成分 | 由丙烯製成 | 由矽氧烷製成 |
彈性 | 彈性較差,容易開裂 | 彈性極佳,能夠拉伸和壓縮 |
防水性 | 防水性差 | 防水性優異 |
耐候性 | 不適合戶外使用 | 適合戶外使用,耐紫外線 |
最佳使用場景 | 室內應用(如窗框、牆面、踢腳線) | 潮濕區域(如浴室、廚房) |
上漆性 | 乾燥後可以上漆 | 一般不能上漆 |
乾燥時間 | 乾燥快(1-2小時) | 固化時間較長(24小時或更長) |
Comparison of Acrylic Caulk and Silicone Sealant
Feature | Acrylic Caulk/Gap Filler (丙烯填縫劑) | Silicone Sealant (矽膠) |
---|---|---|
Composition | Made from acrylic | Made from silicone |
Elasticity | Less elastic, can crack over time | Highly elastic, can stretch and compress |
Water Resistance | Poor water resistance | Excellent water resistance |
Weather Resistance | Not suitable for outdoor use | Suitable for outdoor use, UV resistant |
Best Use Cases | Indoor applications (e.g., windows, walls, trim) | Wet/ Humidity areas (e.g., bathrooms, kitchens) |
Paintability | Can be painted after drying | Generally cannot be painted |
Drying Time | Dries quickly (1-2 hours) | Takes longer to cure (24 hours or more) |
