A single-group silicone sealant is a combination of the main agent and the curing agent to cure with the moisture in the air, and is highly dependent on the air humidity. During the curing process, the curing depth is limited by 6mm, and the adhesive layer with too thick curing depth is difficult to cure; the two-component is divided into two kinds of ab, which need to be matched in proportion when using. When curing, both the inside and outside can be cured at the same time, which can be used for thicker potting.

　　Under what circumstances should one-component silicone sealant be used instead of two-component silicone sealant?

　　Silicone sealant is usually made of a single component, and the single-piece operation is also very convenient. Our exterior wall aluminum panels and insulating glass both use this structure. The structural glue uses two components, such as the insulating glass sub-frame, glue and curing agent are applied in proportion, the curing speed is fast, and the speed can be adjusted.

　　When the two-group silicone sealant ab group is mixed, how does it cure?

　　The principle is the same as that of one-component. The reaction between silicone glue and water, one is water in the air, and the other is solidified water. An organosilane with a hydrolyzable group is used as a crosslinking agent.

　　Which of two-component silicone sealant and single-component silicone sealant dry quickly?

　　uncertain. Since a single combination is a stable ratio, the surface is usually cured within 20 minutes at room temperature, and all curing times are used within 12 hours. If the ratio of the two components is correct, the curing time is similar to that of the single component; if the ratio is incorrect, the curing time will be very fast. If it is curing time, the curing time will be very fast.

　　What is the difference between single and double groups of silicone rubber?

　　Most packages are individually packaged with limited capacity and are more convenient to use on construction sites; two-component packages are packaged in barrels. Most glass processing plants use fully automatic equipment, continuous production, fast curing speed, and emphasis on efficiency. And use two-group structural glue directly on the construction site.

　　The difference between single-group silicone sealant and double-group silicone sealant

　　1. Why are they named as one-component and two-component; 2. The difference in properties and properties. One-component and two-component are for its curing agent; one-component: that is, no other curing agent is needed for curing; component: the glue is composed of group ab, group a is silicone rubber (white), The b group is a curing agent (black). If the curing and bonding effect cannot be achieved by using the a group alone, use ab. The normal ratio is 7:1. That is, 7 groups a and b.

　　What does 　　 single-group silicone structural sealant mean?

　　A silicone structural adhesive used to attach glass and aluminum to the frame when making glass curtain walls. Single component: This refers to the packaging method of this glue. It can pack the product in a packaging bottle (or packaging bag), and can be directly squeezed out and coated on the bonding surface of the glass and aluminum attachment frame during use.

　　Silicone: It means that the main chemical component of this sealant is silicone instead of other chemical components such as polyurethane or polysulfide.

　　Structural sealant: refers to the purpose of this sealant, that is, the glass and aluminum frame when the glass curtain wall is made. Corresponding to the weather-resistant sealant, the weather-resistant sealant is not used for bonding, but for filling and sealing.
