How to distinguish silicone sealant from MS sealant

What is glass sealant?

Silicone sealant commonly known as glass sealant, with polydimethylsiloxane as the main raw material, supplemented by crosslinking agent, filler, plasticizer, coupling agent, catalyst mixed in vacuum paste, at room temperature through the reaction with water in the air, curing to form elastic silicone rubber sealant.

Silicone sealant has strong adhesion, large tensile strength, and has the characteristics of weather resistance, vibration resistance, moisture resistance, odor resistance and adaptation to hot and cold changes. Coupled with its wider applicability, it can realize the bonding between most building materials products, so the application value is very large.

What is MS Sealant?

MS sealant full name silane modified polyether sealant, MS polymer as the base polymer, supplemented by filler, plasticizer, catalyst, silane coupling agent and other functional additives made of one or two component elastic sealant.

MS sealant does not contain formaldehyde, does not contain isocyanate, no solvent, has the environment and human body affinity outstanding environmental protection characteristics, suitable for the vast majority of building substrates. At the same time, it also has good constructability, adhesion, non-pollution and can be painted, which has a wide range of applications in architectural decoration, and its application in the field of refrigerated trucks, containers and elevators is also expanding.

The application range of sealant

Acid silicone sealant is suitable for bonding between most decoration building materials, such as glass, aluminum, oil-free wood and so on. However, it should be noted that acid silicone sealant can not be used to stick alkaline building materials such as ceramics and marble. Otherwise, the substances in the acid silicone sealant will react with the alkaline substances in the building materials, thus affecting the quality of the decoration of the building materials.

Neutral weather-resistant silicone sealant is suitable for weather-resistant sealing of various curtain walls, especially recommended for weather-resistant sealing of glass curtain wall, aluminum-plastic panel curtain wall and stone dry hanging; Joint sealing between metal, glass, aluminum, ceramic tile, plexiglass, coated glass; Joint seals for concrete, cement, masonry, rock, marble, steel, wood, anodized aluminum and painted aluminum surfaces. It is more suitable for interior decoration.

Structural silicone sealant is mainly used for structural or non-structural bonding assembly between metal and glass curtain walls. It can directly connect the glass and the surface of the metal component to form a single assembly component, which meets the design requirements of the curtain wall with full or semi-hidden frame. It can be used to seal the structural bonding of insulating glass.

MS sealant is suitable for prefabricated buildings, concrete joints, prefabricated building joints, etc. The door frame, window sill, interior wall, tile and other parts of the building are caulked and sealed, and the kitchen and bathroom mirrors and pendants are glued; Bonding of various building materials, such as glass, aluminum, concrete, etc. It is widely used in various billboards, vehicles, ships, elevator cars, containers, solar cells and other industrial fields.
