What is silicone glue? Different types of silicone adhesives

Silicone rubber is often called glass glue because it is often used for bonding and sealing glass. Silicone rubber is also commonly used in decoration. What is silicone glue? What are the different types of silicone glues? Xiao Bian has compiled some relevant information. We understand the following:

What is silicone glue?

Silicone gel is an ointment that, once exposed to the moisture in the air, cures into a tough, rubbery, solid material. It is mainly divided into deacetic acid type, de-alcohol type, deamination type, and de-c type. Silicone rubber is often called glass glue because it is often used for bonding and sealing glass.

Silicone glass adhesive has strong adhesive force, large tensile strength, weather resistance, vibration resistance, moisture resistance, odor resistance, and adaptability to large changes in heat and cold. Combined with its wider applicability, it can achieve the bond between most building materials, so the application value is very large.

Silicone rubber how to classify

1, according to product packaging

One-component and two-component:

The one-component silicone adhesive cures by changing the physical properties of the air in contact with moisture;

Two-component means that the silicone glue is divided into two groups, A and B. Any group that exists alone cannot be solidified, but the two groups of glue will cure once mixed. Commonly used in the market is a one-component silicone glass adhesive.

2, according to the nature

Single-component silicone glass adhesives are divided into two types, acidic gels and neutral gels. Acidic glass glue is mainly used for general bonding between glass and other building materials. Neutral gel overcomes the characteristics of acidic gels that corrode metal materials and react with alkaline materials, and therefore has a wider range of applications. Its market price is slightly higher than that of acidic gels.

A special type of glass adhesive on the market is a silicone structural sealant. Because it is directly used for metal and glass structure or non-structural adhesive assembly of glass curtain walls, the quality requirements and product grade are the highest among glass adhesives. The market price is also the highest.

3, by color

Silicone glass glue has a variety of colors, commonly used colors are black, porcelain white, transparent, silver gray, gray, bronze six kinds. Other colors can be customized according to customer requirements.

Different types of silicone adhesives use:

Silicone adhesive use:

Silicone glass sealant does not flow because of its own weight, so it can be used in the joints of the ceiling or side walls without sagging, falling or running away. It is mainly used for dry clean metal, glass, most non-greasy wood, silicone resin, vulcanized silicone rubber, ceramics, natural and synthetic fibers, and many paint plastics surface bonding. The use of good quality silicone glass gels at temperatures below zero degrees Celsius does not result in squeezing or physical changes. Fully cured silicone glass adhesives remain effective at temperatures up to 204°C (400°F), but the effective time is shortened at temperatures up to 218°C (428°F).

Acid glass adhesive use

1, suitable for sealing, plugging leakproof and weatherproof purposes, both indoor and outdoor (improved indoor effect), anti-seepage leak-proof effect is remarkable. 2. Bonding various interior decorations of automobiles, including: metal, fabrics and organic fabrics and plastics. 3. Join gaskets on heating and cooling equipment. 4, the installation of non-threaded ribs, nameplates and paint plus plastic materials on the metal surface. 5. Seal the window on the oven door, the flue on the gas appliance, the pipe joint, and the access door. 6. Provide real-time formed leakproof pads for gearboxes, compressors, and pumps. 7, the shiphouse and the window seal. 8, trailer, truck cab glass window seal. 9, bonding and sealing equipment components. 10. Form a wear-resistant coating. 11. Inlaying and filling thin metal laminations, duct networks and equipment enclosures.

Neutral weatherproof adhesive

1. Suitable for weatherproof sealing of various curtain walls, especially recommended for weatherproof sealing of glass curtain walls, aluminum-plastic panel curtain walls, and stone dry hanging; 2. Joint sealing between metal, glass, aluminum, ceramic tile, plexiglass, and coated glass. 3, joint sealing of concrete, cement, brick, rock, marble, steel, wood, anodized aluminum and painted aluminum surface. Primer is not required in most cases.

Silicone structural adhesive use

1, mainly for the glass curtain wall of the metal and glass structure or non-structural adhesive assembly. 2. It can connect the glass directly to the surface of the metal component to form a single assembly component, meeting the design requirements of the fully hidden or semi-hidden curtain wall. 3. Structural adhesive sealing of insulating glass.
