When it comes to sealing gaps and joints in various applications, two common options are acrylic caulk and silicone sealant. While both types of sealants have their own strengths and weaknesses, they are not interchangeable. In this article, we will compare and contrast the characteristics of acrylic caulk and silicone sealant, helping you to make an informed decision for your specific needs.
Comparison of Acrylic Caulk and Silicone Sealant
| Feature | Acrylic Caulk/Gap Filler (丙烯填縫劑) | Silicone Sealant (矽膠/玻璃膠) |
|---|---|---|
| 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) |
