What is silicone sealant

Generally speaking, in the range of 5~40℃, normal construction can be carried out. When the surface temperature of the substrate is higher than 50℃, please stop the construction. If the construction is continued at this temperature, although the curing speed will be accelerated, at the same time, the small molecular products will not be discharged in time, resulting in the formation of bubbles. When the temperature is too low, the curing speed will slow down, shrinkage may occur, and the adhesive layer will be out of shape. Silicone sealants are not suitable for all occasions, such as places that have been soaked in water for a long time, frosted or too humid, and the surface of the substrate is not clean enough, and it is not easy to bond with oily materials.

The silicone sealant must be stored in a cool and ventilated place. The warehouse needs to be kept away from infants and young children. Do a good job of protection against insects and rodents to avoid waste caused by biting the rubber tube. In the storage stage, it can be stored in accordance with general chemicals, away from fire sources and explosives.

1. Not suitable for long-term immersion in water, so as not to affect the adhesion of the adhesive.
2. It cannot be used on surfaces that are too wet or prone to frost, and cannot be bonded normally.
3. One-component silicone sealant cannot be cured in a completely sealed environment, and may not be completely cured.
4. The surface of the substrate must be kept clean and dry, otherwise it cannot be firmly bonded.
5. Do not use inferior adhesives, so as not to corrode other parts.

1. One-component products can be operated directly with a glue gun; two-component silicone adhesives need to be mixed evenly in proportion.
2. Clean the surface of the bonding object, and clean up oil stains, rust, etc. If necessary, professional cleaning agents can be used, and then appropriate sanding with sandpaper can be used to improve adhesion.
3. Apply the silicone sealant evenly to bond. When bonding the two surfaces, squeeze out the air to avoid affecting the curing effect.
4. It can be cured at room temperature, and the next step can be performed after a period of time.
5. Wipe off excess adhesive with a rag or paper towel. After curing, you can clean it with a blade.
