Classification and Application of Silicone Glue

Mar 11, 2021

Silicone glue is a kind of ointment, once exposed to moisture in the air, it will solidify into a tough rubber-like solid material. It is mainly divided into de-acetic acid type, de-alcohol type, de-ammonia type, and de-C type. Silicone glue is commonly called glass glue because it is often used for bonding and sealing of glass. One-component silicone glass glue is a kind of ointment, once it comes into contact with moisture in the air, it will solidify into a tough rubber-like solid material.

Silicone glass glue has strong adhesion, high tensile strength, and at the same time has weather resistance, vibration resistance, moisture resistance, odor resistance, and adaptability to large changes in cold and heat. Coupled with its wider applicability, it can realize the adhesion between most building materials products, so the application value is very great.
The English name of silicone rubber is SILICONE, which is part of the product of organic silicon. It is mainly divided into deacetic acid type, dealcohol type, deamination type, and deacrylation type. Glass glue is the common name of silicone glue, because users buy silicone sealant mainly used for bonding and sealing of glass, so it is called glass glue.

The chemical composition is polydimethylsiloxane, and the polymer of silica can be called silicone.
Folded by product packaging
One-component and two-component.
One-component silicone rubber, its curing is dependent on contact with moisture in the air to produce changes in physical properties;
Two-component means that the silicone glue is divided into two groups, A and B. Any one of them can not be cured by itself, but once the two groups of glue are mixed, they will be cured
One-component silicone glass glue is common in the market.

By nature
One-component silicone glass glue is divided into acid glue and neutral glue according to its properties.
Acid glass glue is mainly used for general bonding between glass and other building materials. The neutral glue overcomes the characteristics of acid glue that corrodes metal materials and reacts with alkaline materials, so it has a wider range of applications, and its market price is slightly higher than that of acid glue.
A special type of glass glue on the market is the silicone structural sealant. Because it is directly used for the metal and glass structure or non-structural bonding assembly of glass curtain walls, the quality requirements and product grades are the highest among the glass glues. The market price is also the highest.

By color
Silicone glass glue has a variety of colors. Commonly used colors are black, porcelain white, transparent, silver gray, gray, and bronze. Other colors can be customized according to customer requirements.

Edit the purpose of this paragraph
Silicone glass glue does not flow due to its own weight, so it can be used in the joints of overhead or side walls without sag, collapse or run away. It is mainly used for the bonding of dry and clean metal, glass, most grease-free wood, silicone resin, vulcanized silicone rubber, ceramics, natural and synthetic fibers, and many painted plastic surfaces. Good-quality silicone glass glue will not be extruded or changed in physical properties when used below zero degrees Celsius. Fully cured silicone glass glue can remain effective when used at a temperature of 204°C (400oF), but when the temperature is as high as 218°C (428oF), the effective time will be shortened.

Acid glass glue
1. It is suitable for sealing, blocking, leak-proofing and weather-proof purposes. It is suitable for both indoor and outdoor (the indoor effect is better), and the anti-seepage and leak-proof effect is obvious. 2. Bonding various interior decorations of automobiles, including: metal, fabric, organic fabric and plastic. 3. Join the gaskets on the heating and cooling equipment. 4. Install ribs without screw holes, nameplates and paint and 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 passage door. 6. Provide instant-formed anti-leak pads for gearboxes, compressors, and pumps. 7. Seal the cabin and window. 8. Sealing of glass windows in trailers and truck cabs. 9. Glue and seal equipment parts. 10. Form an anti-wear coating. 11. Inlay and fill thin metal sheet laminates, pipe networks and equipment casings.

Neutral weathering glue
1. 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; 2. Joint sealing between metal, glass, aluminum, ceramic tiles, plexiglass, and coated glass ; 3. Seam sealing on the surface of concrete, cement, masonry, rock, marble, steel, wood, anodized aluminum and painted aluminum. In most cases, no primer is needed.

Silicone Structural Adhesive
1. It is mainly used for structural or non-structural bonding assembly between metal and glass of glass curtain wall. 2. It can directly connect the glass and the surface of the metal component to form a single assembly component, which can meet the design requirements of the curtain wall with fully hidden or half hidden frames. 3. Structural bonding and sealing of insulating glass.
Instructions
1. Access: One-component silicone glue can be used immediately, and it is easy to shoot it out of the plastic bottle with a glue gun.
2. Bonding:
A. Wipe the metal and plastic surfaces completely to remove oil stains. First, rinse all surfaces of the plastic with acetone, and polish the rubber surface with sandpaper, and then wipe it with acetone.
B. Spread the silicone glue evenly on the surface of the ready object. If you are bonding two surfaces together, you can locate one side first, and then use enough force to squeeze the other side to squeeze out the air, but Be careful not to squeeze the glass glue.
C. Put the bonded device at room temperature and wait for the glue to solidify.
3. Sealing: When silicone glue is used for sealing, follow the same steps as mentioned above, squeeze the glue into the joint surface or gap to make the glass glue fully contact the surface.
4. Cleaning: The glass glue can be wiped off with a cloth or paper towel before it is cured. After it has been cured, it must be scraped off with a spatula or scrubbed with solvents such as xylene and acetone.
