MS Sealant vs Silicone Sealant: Selection Guide for Contractors & Distributors
1. MS Sealant
MS Sealant (Modified Silane) is an eco-friendly sealant that combines the high strength of polyurethanes with the weather resistance of silicones.
Paintable without Primer
Unlike silicone, MS Sealants are fully paintable once cured. Whether it’s door frames or wall joints, you can apply matching paint to achieve an invisible finish with interior projects.
ECO-friendly Formula
Does not contain toluene, formaldehyde, thinners, or other toxic solvents.
Multi Substrates Adhesion
MS Sealants bond exceptionally well to wood, metal, glass, and plastic. They are ideal for:
- Floor joints and baseboard installation.
- Kitchen and bathroom sealing (anti-mold and eco-friendly).
2. Silicone Sealant
Silicone Sealant provides superior UV resistance, making it suitable for outdoor engineering applications.
Excellent Weather & UV Resistance
Outdoor environments subject sealants to intense UV rays, heavy rain, and temperature swings. Silicone sealants do not degrade or yellow under prolonged sun exposure. They remain flexible in temperatures ranging from -50°C to 150°C.
High Structural Bonding Strength
Structural silicone sealants are designed for high-load applications and long-term durability. They are widely used in:
- Glass curtain walls
- Sunrooms
- Structural glazing
