Application of silicone structural adhesive

When silicone structural adhesive is in direct contact with air, it will react with moisture in the air and solidify into a tough rubber-like substance. Silicone adhesive is very sticky, so it is often used as a connecting agent between building materials.

Application of silicone structural adhesive

1, acidic glass glue. Acid glass glue has very good elasticity and adhesion, and has a wide range of applications. It can be used to bond most decorative building materials, such as glass, aluminum and oil-free wood. However, it should be noted that acidic silicone adhesive can not be used to bond alkaline building materials such as ceramics and marble. Otherwise, the substances in the acidic silicone adhesive will react with the alkaline substances in building materials, thus affecting the decoration quality of building materials.

2. Neutral weather-resistant adhesive. Neutral weather-resistant adhesive is mostly used in weather-resistant sealing construction of various external walls and building curtain walls, especially glass curtain walls, which has a very strong viscosity. Neutral weather-resistant adhesive is widely used. Whether it is acidic or alkaline building materials, it can be bonded with neutral weather-resistant adhesive. Moreover, when neutral weather-resistant adhesive is used to bond stone and painted aluminum, it does not even need to be painted with primer.

3. Silicone structural adhesive. Silicone structural adhesive is mainly used for bonding between metal and glass in glass curtain wall. It can directly connect the glass curtain wall with the surface of metal objects to form a group of components, which can meet people's design requirements for hidden curtain walls. Silicone structural adhesive can also be used in the sealing construction of insulating glass to structurally bond and seal insulating glass, thus ensuring the sealing requirements of insulating glass.

Identification of silicone adhesive

1. Apply silicon adhesive between substrates, dry, pull apart substrates, observe their breaking strength, and then measure their elongation at break.

2. Observe whether there are bubbles or particles in the coated silicone adhesive. If there are bubbles or particles, the quality of silicone adhesive is not very good. According to the curing time, the shorter the curing time, the higher the quality.
