Why Choose MS Sealant Over Traditional Silicone? A Smarter, Greener Solution for Modern Construction

Published by Hilkem – Experts in Sealants and Construction Solutions
In the evolving world of construction and industrial sealing, material performance, environmental impact, and application versatility are top priorities. At Hilkem, we are committed not only to delivering high-performance sealants but also to promoting sustainable and safe solutions. One of the most important advances in recent years is the shift from traditional silicone sealants to more modern, eco-friendly MS sealants (Modified Silane sealants).
But what exactly makes MS sealants a better choice?

One of the most significant advantages of MS sealant is its environmental safety. Unlike conventional silicone sealants, which may release harmful solvents or siloxanes into the air, MS sealants are free from isocyanates and solvents, resulting in ultra-low VOC (Volatile Organic Compounds) emissions.
✅ Low VOC = Safer Indoor Air Quality
✅ No strong odors during application
✅ Eco-conscious choice for green building certifications (LEED, BREEAM)

Traditional silicone sealants are known for their non-paintable surface — a major limitation in many interior and exterior design applications. In contrast, MS sealants are fully paintable after curing.
Perfect for seamless wall and joint finishes
Compatible with water-based and solvent-based paints
This makes MS sealants especially suitable for projects where aesthetics and finish matter just as much as durability.

MS sealants provide excellent adhesion to a wide range of substrates, including concrete, metal, wood, glass, and even damp surfaces—without the need for a primer. Their superior elasticity ensures long-term performance even under dynamic movement and stress.
