Although acrylic building sealant and MS building sealant are both building sealing materials, they differ greatly in chemicla structure, performance, use and grade. Below I will list it clearly for you.
| Comparison items | Acrylic Building Sealant | MS Building Sealant |
| Main ingredients | Acrylic emulsion (water-based) | MS polymer (modified silane polyether) |
| Cure method | Cures by water evaporation | Cures by reacting with moisture in the air (moisture cure) |
| System type | Water-based system | Neutral, one-compoent system |
| Odor | Low odor or slight emulsion odor | Odorless, environmentally friendly |
| Contains solvents | Aqueous system (low amount of additives) | Solvent-free, extremely low VOC |
| Performance specification | Acrylic Building Sealant | MS Building Sealant |
| Elasticity and elongation | Low (<150%) | High (200-600%) |
| Weather resistance | General, prone to aging and cracking | Excellent, UV and water resistant, non-chalkable |
| Adhesion | Suitable for porous materials (e.g., cement, gypsum board) | Strong adhesion to most substrates, no primer required |
| Paintability | Paintable | Paintable (better compatibility) |
| Cure speed | Slow (depending on ambient humidity) | Moderate (full cure in 24 hours) |
| Environmental performance | Water-based, environmentally friendly | Solvent-free, VOC-free, higher environmental rating |
| Price | Low cost | Higher cost (approximately 2-3 times) |
| Application | Recommended Sealant Types |
| Interior decoration, wall crack repair, wood molding sealing | Acrylic building sealant |
| Curtain wall, door and window joints, exterior wall expansion joints, waterproof joints | MS building sealant |
| Kitchen and bathroom mildew prevention, waterproof sealing | MS building sealant |
| Floor gaps, structural joints | MS building sealant |
| Acrylic Building Sealant | MS Building Sealant | |
| Positioning | Economical, indoor use | High-performance, genral-purpose |
| Weather resistance | Average | Excellent |
| Elasticity | Low | High |
| Environmental protection | Good | Excellent |
| Comprehensive performance | Suitable for low-demand applications | Can replace silicone sealant in various applications |
