What are MS Polymer Adhesives & Sealants?
MS Polymers are moisture-curing elastic adhesives and sealants, based on silyl-modified polymer (SMP) technology. MS polymers combine all of the best properties of one-component polyurethane and silicones whilst limiting their individual inherent weaknesses. This is due to modified silane chemistry having a high weathering resistance (silicone technology) and high-performance bonding properties (polyurethane technology).
There is a wide spectrum of MS polymers that range from low-strength sealants to high-strength structural adhesives. The properties of the adhesive or sealant can easily be modified for specific applications and requirements (e.g. strength, flexibility, hardness, adhesion range, etc.)
MS polymer sealants are mostly supplied in one-component systems which are moisture-curing, meaning they cure through exposure to air or moisture in the atmosphere at ambient temperatures. MS polymer sealants are sometimes supplied in two-component systems, which use water present in the secondary component as the ‘activator’, as opposed to atmospheric moisture.
MS Polymer Adhesives & Sealants Range of Applications
The application of MS polymer is vast and there are many industries that require a tough, flexible bond. MS polymer sealants and adhesives are used in a wide range of industries and applications, including the following:
- Construction and building fabrication
- Exterior perimeter sealing
- Exterior joint sealing
- Exterior cladding
- Elastic bonding of strips, profiles, sheets
- Boat and shipbuilding
- Structural bonding in vibration constructions
- Connection joints in sheet metal fabrication
- Supple bonding in automotive vehicles, recreational vehicles etc.
- Glass bonding
- Bus and coach
- Truck body
- Trains and rail
