ms polymer sealant
Our MS polymer Sealant is single-component, solvent-free, and moisture-curing, making it highly user-friendly while delivering long-lasting results. It is engineered to withstand thermal expansion, and mechanical stress, providing a reliable seal for a wide variety of materials.
Our MS polymer Sealant (Modified Silicone Sealant) is a high-performance, versatile sealant suitable for construction, industrial, and transportation applications. the MS sealant provides superior weather resistance, elasticity, and adhesion, making it an ideal choice for modern sealing projects.
Features of MS polymer sealant:
- Exceptional Elasticity and Flexibility: With an elongation at break exceeding 300%, MS Sealant can absorb structural movement without cracking, ideal for expansion joints and dynamic applications.
- Superior Adhesion: Bonds directly to concrete, metals, glass, wood, PVC, and other common substrates without the need for a primer, saving time and labor costs.
- Chemical and Corrosion Resistance: Provides protection against moisture, chemicals, and environmental pollution, extending the lifespan of sealed surfaces.
- Eco-Friendly and Safe: Low VOC formulation ensures minimal environmental impact and safe handling for construction personnel.
Applications of MS sealant:
MS Sealant and MS Polymer Sealant are widely used in:
- Construction: windows, doors, and waterproof joints.
- Industrial Manufacturing: Equipment sealing, dustproofing, waterproofing, and vibration damping.
- Transportation: Automotive, marine, and rail sealing and sound insulation.
- Special Applications: Electronics sealing, corrosion protection, and decorative finishing.

How to Use ms polymer sealant:
- Surface Preparation: Clean surfaces thoroughly; remove dust, grease, and loose particles.
- Cut Cartridge Tip: Fit a nozzle to the cartridge and cut to desired bead size.
- Application: Apply MS Sealant evenly using a caulking gun; smooth with a spatula or finger dipped in soapy water for a neat finish.
- Curing: Allow sealant to cure at ambient temperature; curing speed depends on humidity and thickness. Full cure typically achieved in 24–48 hours for 5mm thickness.
- Cleaning: Uncured sealant can be removed with alcohol or recommended cleaning agents; cured sealant must be removed mechanically.
