Acid silicone sealant & neutral silicone sealant, Which should you choose?

Concept:

Sealant is a common adhesive, the effect is better, but after the sealing adhesive bonded items, need to be completely dry before use. Sealant is also called silicone sealant, acid and neutral two. According to the use of neutral silicone adhesive, it can be divided into curtain wall structural adhesive, curtain wall weatherproof adhesive, door and window sealant, stone sealant, mildew proof sealant, fire sealant, insulating glass sealant and so on.

The difference:

Acid adhesive has very good elasticity and adhesion, its use is very wide, can be used for most of the decoration building materials between the bonding, such as glass products, aluminum, oil-free wood and so on. However, it should be noted that acidic 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. (with a certain pungent smell)

Neutral adhesive is suitable for weatherproof sealing of various curtain walls, especially recommended for weatherproof 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. Primer is not required in most cases.

Many people will not be clear when buying acid silicone sealant and neutral silicone sealant, so that unnecessary trouble, acid glass sealant bonding force is strong, some materials have a certain corrosion, applicable materials are limited, irritating taste is also large, such as the installation of mirrors if the acid glass sealant will lead to the mercury on the back of the corrosion.

Neutral glass sealant is suitable for marble, metal, doors and Windows, bathroom, curtain wall and other materials, the irritating taste is less, but the curing time is slower than acid.

In general, the bathroom basin and toilet, kitchen countertops should be selected with mildew resistant glass sealant, acid or neutral; Metal ceiling, shower room, mirror should choose mildew neutral glass sealant, not acid; Smoke stove, Windows should choose weather-resistant neutral glass sealant. The water resistance and bonding performance of the aquarium glass sealant are very high, and advanced acid sealant should be used.
