Features of construction sealant
After curing, it has excellent weather resistance characteristics and excellent UV resistance, high and low temperature resistance, corrosion resistance and temperature performance. The neutral dealcoholization type cures at room temperature, and the curing agent can be adjusted to cure it even when the temperature difference changes greatly.
Its typical physical properties can form excellent structural strength at -30°C to 120°C. Primer two-component silicone sealant generally does not need primer, but if the adhesion test report indicates that it is necessary to use the primer, before applying the sealant, use a clean, non-linting cloth to coat the primer on the base surface. Spread a thin layer and let it dry. Before applying the sealant, a test must be done to determine whether a primer is required.

Frequently Asked Question
Do you have any question?
Hardness after curing. If the hardness of the sealant is low after curing, and it will collapse when pressed by hand, then such a sealant will have outstanding other properties in time, and it cannot be widely used in electrical appliances or electronics. Whether the surface is smooth after curing. A good sealant can be changed following the shape of the sealing surface, and the surface will not be deformed or uneven after curing.
Only when the various properties of the sealant are guaranteed after curing, can it be a good-quality sealant that can be used in various fields. However, the performance of the sealant cannot be guaranteed before it is cured, and related tests can be carried out after curing, so that various performance indexes are guaranteed. But for the sake of safety, it is best to cooperate with branded products, so that the quality is guaranteed.
1. Cleaning. There are generally dust and loose parts on the surface of the concrete, which need to be thoroughly cleaned to ensure the bonding effect. 2. Primer. Concrete wall panels are made on the factory production line, and a certain amount of release agent will remain on the surface of the panels, which will affect the bonding effect. If the surface of the substrate is not thoroughly cleaned and a suitable primer is applied, it is very easy to cause bonding failure. 3. Deal with bad interface. The part of the glue joint was accidentally sprayed with paint during the paint application, and the compatibility of the paint and the sealant was not good, resulting in debonding. 4. In order to save glue, the construction unit responsible for the glue application has made the sealant very thin, and the thickness of some parts is even less than 5 mm, which makes it easy to debond.
