What is general purpose silicone sealant used for?

Sealant is a common adhesive with relatively good results, but items bonded with sealant need to be completely dry before use. Sealant, also called silicone sealant, is divided into two types: acidic and neutral. Neutral silicone glue can be divided according to its use, and can be divided into curtain wall structural glue, curtain wall weather-resistant glue, door and window sealant, stone sealant, anti-mildew sealant, fireproof sealant, insulating glass sealant, etc.

Acid sealant has very good elasticity and adhesion. It has a wide range of uses and can be used to bond most decorative building materials, such as glass products, aluminum materials, oil-free wood, etc. However, it should be noted that acidic silicone glue cannot be used to stick to alkaline building materials such as ceramics and marble. Otherwise, the substances in the acidic silicone glue will react with the alkaline substances in the building materials, thus affecting the decoration quality of the building materials. (has a certain pungent smell)

Neutral sealant is suitable for weather-resistant sealing of various curtain walls, and is especially recommended for weather-resistant sealing of glass curtain walls, aluminum-plastic panel curtain walls, and dry-hanging stone; joint sealing between metal, glass, aluminum, ceramic tiles, organic glass, and coated glass ;Joint sealing on concrete, cement, masonry, rock, marble, steel, wood, anodized and painted aluminum surfaces. In most cases there is no need to use primer.

Many people cannot distinguish between acidic silicone glue and neutral silicone glue when purchasing, causing unnecessary trouble. Acidic glass glue has strong adhesion and is corrosive to some materials. It is suitable for limited materials and is irritating. The smell is also strong. For example, if you use acidic glass glue to install a mirror, the mercury on the back will be corroded.

Neutral sealants are suitable for marble, metal, doors, windows, bathrooms, curtain walls and other materials. They have less irritating smell, but the curing time is slower than acidic ones.

Generally speaking, bathroom basins and toilets, and kitchen countertops should choose glass glue with anti-mold properties, which can be acidic or neutral; metal ceilings, shower rooms, and mirrors should choose anti-mold and neutral glass glue. , and acidic ones cannot be used; weather-resistant neutral glass glue should be used for hoods, stoves, and windows. Fish tanks have very high requirements for the waterproofing and bonding properties of glass glue, so high-grade acid sealants should be used.
