First point: Use glass glue and structural glue Glass glue is mainly used for sealing between glass and window frames, glass and glass, window frames and walls, and ceramic tiles. Its main purpose is to connect and seal. Glue has a good sealing effect; Structural adhesive is mainly used in construction projects and is a tool for structural bonding, such as the connection between TV background wall wooden frames and tiles, and the bonding between solar room frames and glass. For the bonding or adhesion between glass and tiles, structural adhesives will provide better adhesion in these areas. Second point: Type and color Glass glue is divided into acidic and neutral glass glue, and there are many colors available. Common is transparent glass adhesive, except for black, white, bronze, silver, etc. Structural adhesives are mainly divided into high-performance organic silicon structural adhesives and neutral transparent structural adhesives. The color of structural adhesive is relatively simple, basically black. Third point: viscosity and hardness In terms of viscosity and hardness, structural adhesives must be better, as the main purpose of glass adhesives is to have better sealing properties. Although it also has adhesive properties, the purposes of the two adhesives are basically different. The price is usually twice that of glass glue, so you can choose which glue to use according to your own needs. Fourth point: Can the two types of glue be used interchangeably? Many friends think that these two types of glue look similar, so they think they can be used interchangeably. The correct answer is actually negative, because structural adhesive is a type of adhesive with strong viscosity, while glass adhesive is a type of water with good sealing performance and average viscosity. The functions of the two are not concepts, so they cannot be used interchangeably.
Silicone adhesive is a type of sealant that is formed from materials such as sodium silicate, organosilicon, and silicone structural polymers. Silicone sealant has good adhesion to most substrates, transparent products, moderate mechanical strength, and fast surface curing speed. Silicone sealant is widely used for sealing seams between various types of glass, metal, aluminum, ceramic tiles, organic glass, and coated glass. Silicone sealant is a good helper for house decoration and a good companion for automobile manufacturing and maintenance. Basic uses of silicone sealant 1. Widely used, silicone sealant can be used to bond dry and clean metals, glass, most oil-free wood, silicone resin, sulfurized silicone rubber, ceramics, natural and synthetic fibers. 2. Used for the installation of aluminum alloy doors and windows, titanium alloy doors and windows, and plastic steel doors and windows, used for filling and sealing seams, and strengthening the adhesion of objects. 3. Silicone sealant can be used for bonding and sealing of buckle doors and windows. 4. Sealing of joints between various types of glass, metal, aluminum, ceramic tiles, organic glass, and coated glass. 5. Silicone sealant is suitable for weather resistant sealing of various glass curtain walls, aluminum-plastic panel curtain walls, stone dry hanging, etc. 6. There is also the function of bonding ceramics, sanitary ware, and marble, which many people may overlook. 7. Suitable for joint sealing on surfaces of concrete, cement, masonry, rock, marble, steel, wood, anodized aluminum, and painted aluminum, and in most cases, primer is not required. Precautions for using silicone sealant 1. Silicone sealant should be stored in a cool and dry place between 4-27 degrees Celsius to maintain its original sealed state; 2. From the production date, the general shelf life is around 6 months; 3. Silicone sealant should not be used on the surface of building materials that have leaked grease, plasticizers, or other solvents; 4. Do not use on painted surfaces as it may cause sealing failure due to cracking or peeling of the paint film; 5. It should not be used on surfaces that come into direct contact with food or in areas that are prone to mechanical wear and tear to avoid accidental ingestion; 6. It is recommended not to use it at noon or when the surface temperature of building materials is below 4 ℃ or above 40 ℃, in order to avoid not achieving the desired effect.
