Le mastic de soudure et le mastic mural sont tous deux utilisés pour combler les lacunes et les imperfections., mais ils servent à des fins très différentes et ont des caractéristiques de performance distinctes. Les principales différences de performances entre le mastic pour joints de soudure et le mastic mural:
| Caractéristiques | Welding seam filler | Mastic mural |
|---|---|---|
| Primary use | Mainly used to fill the gap produced by welding, plays a sealing, anticorrosion, beautiful role. | It is mainly used for wall leveling to provide a flat base for subsequent decoration. |
| Performance | It has strong adhesion, résistance aux intempéries, and corrosion resistance, and can be firmly adhered to the metal surface and resist the influence of the external environment. | It has good plasticity, easy construction, can fill the unevenness of the wall flatly, and has good compatibility with the subsequent paint, wallpaper, and other decorative materials. |
| Formulas | It usually contains metal powder, antirust pigments, and other ingredients to enhance its anticorrosive properties. | The main ingredients are filler, binder, l'eau, etc. The formula is relatively simple. |
| Requirements for construction | The treatment of weld seams is more demanding, requiring the surface of the weld to be cleaned and then putty to be applied in layers to ensure the filling effect. | The treatment requirements for the wall are relatively low and usually only a simple base treatment is needed. |
Welding seam filler
- Welding seam filler is designed to adhere strongly to metal surfaces, often in harsh environments. It offers excellent adhesion to metal and can withstand vibration, temperature fluctuations, and exposure to elements.
- Welding seam filler is typically more durable and resistant to abrasion, produits chimiques, and moisture.
- Welding seam filler often contains metal particles or epoxy resins to enhance its strength, durabilité, and adhesion to metal.
Mastic mural
- Wall putty is formulated for adhesion to drywall, plâtre, and other interior building materials.
- Wall putty is designed for interior use.
- Wall putty is typically composed of water-based acrylic or latex polymers, charges, and binders.
