了解丙烯填和硅膇密封劅的差异，包括它们的组成、弹性、水抵抗和耐候性。找出它们的最佳用途，做出明智的选择。
丙烯填缝剂与硅胶的对比
| 特性 | 丙烯填缝剂 (Acrylic Caulk/Gap Filler) | 硅胶 (Silicone Sealant) |
|---|---|---|
| 成分 | 由丙烯制成 | 由硅氧烷制成 |
| 弹性 | 弹性较差，容易开裂 | 弹性极佳，能够拉伸和压缩 |
| 防水性 | 防水性差 | 防水性优异 |
| 耐候性 | 不适合户外使用 | 适合户外使用，耐紫外线 |
| 最佳使用场景 | 室内应用（如窗框、墙面、踢脚线） | 潮湿区域（如浴室、厨房） |
| 上漆性 | 干燥后可以上漆 | 一般不能上漆 |
| 干燥时间 | 干燥快（1-2小时） | 固化时间较长（24小时或更长） |
Comparison of Acrylic Caulk and Silicone Sealant
| Feature | Acrylic Caulk/Gap Filler (丙烯填缝剂) | Silicone Sealant (硅胶) |
|---|---|---|
| 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) |
