Overview of MS Sealant

Silane-modified resins encompass a range of materials including Silane-Modified Polyether (MS), Hybrid Polyether (STPE), and Silane-Modified Polyurethane (SPU). Prominent manufacturers in this field include Kaneka (Japan), Wacker (Germany), and Momentive (USA). Among them, MS resins from Kaneka dominate the market due to their widespread applications. MS sealants are formulated using MS resins as the base polymer, combined with fillers, plasticizers, and other functional additives to create either one-component or two-component elastic sealants. Notably, MS sealants stand out for their environmental friendliness, being formaldehyde-free, isocyanate-free, and solvent-free, making them highly compatible with most building substrates.

Performance Characteristics of MS Sealant

Currently, silicone sealants dominate the domestic construction sealant market. However, MS sealants offer numerous and superior advantages:

1. Health & Environmental Friendliness: Traditional sealants may release harmful substances like formaldehyde and VOCs due to their solvent content. In contrast, MS sealants are formaldehyde-free, isocyanate-free, solvent-free, non-toxic, odorless, and have VOC emissions far below national standards, making them the most environmentally friendly construction adhesive products.
2. Substrate Non-contamination: MS sealants do not contain any volatile solvents or migratory plasticizers, nor do they contain silicone oil or silicone resin. Their low surface energy prevents small molecules from migrating to the surface and contaminating the substrate.
3. Versatile Substrate Adhesion: The low surface energy and high penetration power of MS resin polymers enable MS sealants to wet most inorganic, metallic, and plastic substrates effectively, resulting in strong adhesion. MS sealants not only adhere well to most building materials but also exhibit excellent bonding strength to engineering plastics such as acrylic, ABS, plexiglass, and porous materials like concrete, offering a broader application scope and stronger adaptability compared to silicone sealants.
4. Paintability: While ordinary silicone sealants cannot be painted or colored on their surfaces, MS sealants can be painted or colored, providing excellent paintability.
5. Excellent Mechanical Properties: The molecular structure and crosslinking characteristics of MS polymers determine the mechanical properties of MS sealants. With adjustable moduli ranging from low to high, they possess appropriate stress relaxation capabilities and elastic recovery rates. MS sealants can accommodate joint expansion, contraction, wind loads, seismic effects, and differential settlement, ensuring the integrity of building seals under adverse conditions.

Applications of MS Sealant

Construction Applications:

MS resins can be formulated into various types of MS sealants such as non-polluting sealants, prefabricated assembly sealants, tile adhesives, and window and door sealants for sealing and filling gaps in various parts of buildings

Interior Decoration Applications:

MS resins are used to create no-nail glues, mildew-proof sealants, edge sealing glues, wall panel glues, and floor glues for interior decoration purposes

Industrial and Automotive Applications：

MS resins can be formulated into high-strength, high-elasticity, and high-modulus MS sealants for use in vehicle manufacturing, ceiling bonding, containers, train carriages, automotive interiors, air-conditioning equipment, elevators, boats, and yachts.
