Sealant is a common adhesive with good effect, but after the sealant is used to bond objects, it must be completely dried before it can be used. Sealant is also called silicone sealant, which is divided into two types: acidic and neutral. Neutral silicone adhesives are classified according to their uses, and can be further divided into curtain wall structural adhesives, curtain wall weathering adhesives, door and window sealants, stone sealants, mildew-proof sealants, fire-resistant sealants, insulating glass sealants, etc.

Acid glue has very good elasticity and adhesion, and its application range is very wide. It can be used for bonding most decoration building materials, such as glass products, aluminum materials, and oil-free wood. But it should be noted that acidic silicone glue cannot be used to stick alkaline building materials such as ceramics and marble. Otherwise, the substances in the acidic silicone rubber will react with the alkaline substances in the building materials, thereby affecting the decoration quality of the building materials. (Has a certain pungent smell

Neutral glue is suitable for weather-resistant sealing of various curtain walls, especially recommended for weather-resistant sealing of glass curtain walls, aluminum-plastic panel curtain walls, and stone dry hanging; seam sealing between metal, glass, aluminum, ceramic tiles, plexiglass, and coated glass; Joint sealing of concrete, cement, masonry, rock, marble, steel, wood, anodized aluminum and painted aluminum surface. In most cases, no primer is needed.
Many people don’t know the difference between acid silicone glue and neutral silicone glue when they buy it, so that unnecessary trouble occurs. Acid glass glue has strong adhesion and is corrosive to some materials. The applicable materials are limited and irritating. The smell is also great, if the acid glass glue is used to install the mirror, the mercury on the back of the mirror will be corroded.
Neutral glass glue is suitable for various materials such as marble, metal, doors and windows, bathroom, curtain wall, etc. It has less irritating taste, but the curing time is slower than that of acid.

Generally speaking, glass glue with anti-mildew properties should be selected for bathroom basins and toilets, and kitchen countertops, which can be acidic or neutral; metal ceilings, shower rooms, and mirrors should choose anti-mildew neutral glass glue , But not acidic; hoods, stoves, windows should choose weather-resistant neutral glass glue. Fish tanks have high requirements for the waterproof and bonding performance of glass glue, and high-grade acid sealant should be used.
Generally, the packaging of most silicone sealants will indicate the materials that they are suitable for bonding, or take the initiative to inform the merchants of the specific sealant usage scenarios, and they will generally get reasonable purchase recommendations.
