Despite their comparatively recent surge in popularity, MS polymer sealants have been around since the late 1970s. Japanese company Kaneka originally developed MS polymers as a durable, highly elastic structural sealant to help protect buildings from the devastating effects of Japan’s frequent earthquakes. Since then, researchers have optimized, refined, and specialized MS polymer formulations into the versatile and performance-driven solutions used today.

What Is MS polymer?

MS Polymer, short for "Modified Silane Polymer," is a revolutionary adhesive and sealant technology that combines the best features of traditional polyurethane and silicone-based products. It is a versatile material that exhibits excellent adhesive strength, flexibility, durability, and weather resistance.

MS Polymers are developed by modifying the chemical structure of silane polymers, resulting in enhanced performance characteristics. They are typically solvent-free, low VOC (volatile organic compound), and possess excellent UV and water resistance properties, making them ideal for a wide range of applications in the construction sector.

Our MS Polymer Sealant is a high bond strength, single-component joint sealant with high levels of elasticity. The applicator tube is easy to gun out, even in low temperatures. It also offers excellent resistance to a wide range of chemicals. MS Sealant is incredibly quick and easy to work with, with primerless adhesion available on most surfaces. It also helps to reduce bubble formation for a strong, unified bond.

MS Polymer Curing Process

MS polymers consist of a polyether backbone with dimethoxy-silyl or trimethoxy-silyl ends, with trimethoxy-silyl groups being more reactive. Backbones can be linear with single or double ends, or branched for an increased amount of cross linking. Precursors can also be varied in the molecular weight and reactive silyl group concentration, resulting in variable cure times, strength, density, and hardness.

The products cure from a liquid or gel state to a solid. Curing entails crosslinking by the hydrolysis of silyl ethers:

2 RSi(OCH3)2R' + H2O → [RSi(OCH3)R']2O + 2 CH3OH

In a hydrolysis reaction, a catalyst and moisture are required to form an intermediate silanol, which then reacts to form siloxane linkages in a condensation process.

Advantages of MS Polymer

• Superior Adhesive Properties: MS Polymers offer exceptional bonding capabilities across various substrates, including metals, plastics, glass, concrete, and wood. The adhesive strength ensures a reliable and long-lasting bond, even in challenging environments.

• Excellent Flexibility and Elasticity: One of the standout features of MS Polymers is their flexibility and elasticity. This enables them to accommodate movements and vibrations without cracking or losing adhesion, making them ideal for applications where joint movement or structural flexing is expected.

• Weather Resistance: MS Polymers are designed to withstand extreme weather conditions, including temperature variations, UV radiation, and moisture exposure. They retain their performance properties over time, making them suitable for both interior and exterior applications.

• Paint Compatibility: Unlike certain adhesive and sealant materials, MS Polymers are compatible with most paints, allowing for seamless integration into a wide range of construction projects. This feature ensures a smooth and aesthetically pleasing finish.

• User-Friendly and Environmentally Friendly: MS Polymers are generally solvent-free, reducing the release of harmful emissions during application. They are also easy to handle and apply, making them user-friendly for professionals and DIY enthusiasts.

MS Polymer Applications:

• Automotive applications where silicone is banned

• Ship-deck caulking, ship & boat building

• Structural bonding in vibration constructions

• Connection joints in sheet metal fabrication

• Supple bonding in car bodies, caravans & containers

• Construction & building fabrication

• Glass panel bonding

• Lighting lenses

• Potting & sealing

• Bathroom applications

• Decorative water feature sealing

Advantages of MS polymer for users

Not only does MS polymer provide significant benefits to the end product, there are also 4 major benefits to the user:

• Free of solvensts, isocyanates and silicones; no hazard labels;

• People and environmental-friendly;

• MS polymer hardly sticks to the skin and can easily be washed off (if it has not yet cured);

• Virtually odor-neutral.
