1-MS vs Silicone vs Polyurethane Sealants
The comparison table above highlights the key differences between 1-MS (modified silicone), silicone sealants, and polyurethane (PU) sealants in terms of durability, UV resistance, paintability, and staining.
Silicone sealants offer very good UV and heat resistance but are not paintable and are prone to staining caused by silicone oil, dust, and fungus. This often affects long-term appearance, especially in architectural applications.
Polyurethane sealants are paintable and provide good adhesion, but they have poor UV and heat resistance and typically require painting to maintain durability in outdoor environments.
1-MS sealant combines the strengths of both systems. Modified Silicone sealants are paintable, resistant to staining, and offer good durability and UV resistance. This makes 1-MS sealant a practical choice for applications that require clean finishes, long service life, and reliable performance.
