Why choose MS sealant

The selection of MS sealant (modified silane sealant) as a bonding and sealing material in the construction or industrial field is mainly based on its excellent comprehensive performance, especially in terms of environmental protection, durability, construction convenience and wide applicability. The following are the main reasons for choosing MS sealant:

1. Core advantages
Environmentally friendly and non-toxic, healthy and safe

No solvent, isocyanate, silicone ingredients:

No irritating odor, no harmful gas is generated during construction (such as the carcinogenic risk of isocyanate in polyurethane glue).

Comply with EU REACH, RoHS and other environmental protection standards, suitable for sensitive places such as interior decoration, hospitals, and schools.

Low VOC emissions: more friendly to the environment and the human body.

Excellent bonding performance

Widely bonded substrates:

No primer is required to firmly bond concrete, metal (aluminum, stainless steel), plastic (PVC, ABS), glass, wood, stone, etc., solving the problem of mixed construction of multiple materials.

Weather resistance and durability:

Anti-ultraviolet aging (no yellowing and cracking after long-term exposure), high and low temperature resistance (stable performance from -40°C to 120°C), service life of more than 20 years.

High elasticity and displacement capacity

Elastic recovery rate>90%:

Can withstand ±25%~50% joint displacement (much higher than ±20% of ordinary silicone glue), suitable for expansion joints and vibrating parts (such as curtain walls and bridges).

Good fatigue resistance: still maintains sealing after repeated expansion and contraction.

Excellent weather-resistant sealing

Waterproof and moisture-proof: still maintains sealing after long-term immersion, suitable for humid environments such as roofs and pools.

Pollution resistance: the surface is not easy to accumulate dust (compared with silicone glue, which is easy to absorb dust and turn black), and it maintains beauty for a long time.

2. Construction convenience
Tool washing and cleaning:

Uncured colloid can be directly washed with clean water, and construction tools (glue gun, scraper) do not need solvent cleaning.

Good coating performance:

The paste is fine, extrusion is smooth, and it is easy to scrape and modify.

Controllable curing:

The surface drying time is about 30~60 minutes (under 50% humidity), and the deep curing speed is moderate, which is easy to adjust.

Paintability:

After curing, the surface can be covered with paint and coating to achieve beautiful and unified appearance (silicone glue cannot be painted).

 

4. Typical application scenarios
Building curtain walls and doors and windows:

Curtain wall joints, door and window frame sealing (bonding aluminum, glass, composite panels).

Interior decoration:

Kitchen and bathroom waterproof sealing (ceramic tile joints, bathtub edges), wooden floor expansion joints.

Industrial field:

Containers, ship cabins, car body sealing (bonding metal and plastic).

Infrastructure:

Bridge expansion joints, concrete prefabricated parts splicing.

5. Selection recommendations
Scenario where MS glue is preferred:

Dynamic joints with high elasticity and strong bonding of multiple materials (such as curtain walls, prefabricated buildings).

Indoor projects with high environmental protection requirements (hospitals, residences, food workshops).

Aesthetic parts that require surface painting (such as colored aluminum plate joints).

Humid or temperature-difference environments (roofs, outdoor facilities).

Cost considerations:

MS glue has a higher unit price than silicone glue and polyurethane glue, but has a long overall life and low maintenance costs, and has better long-term cost performance.

Summary:
MS sealant has become the first choice for high-end construction and industrial sealing due to its environmentally friendly and safe, universal bonding, high elasticity and weather resistance, and construction-friendly features. Especially in today’s pursuit of sustainable development and construction efficiency, its comprehensive performance far exceeds that of traditional adhesives, and it is an ideal solution that takes into account both performance and safety.
