How much do you know about the selection of sealant? Follow the editor of MS SEALANT FOR INDOOR DECORATION to have a simple understanding!

As there are more and more sealant product brands, the selection should be based on comprehensive considerations such as the use conditions of the seal part, the material of the seal pair, the state of the joint surface of the seal pair, the type and performance of the sealed medium and the curing conditions before use. . Regarding the conditions of use: including the stress state, working temperature, environment, and whether the sealing sub-parts need to be detachable, etc. Regarding the material of the sealing pair: Generally, low-strength sealant can be used for non-metallic parts. For metal parts, high-strength sealant should be used. Regarding the state of the sealing sub-parts: it includes the gap size and shape, surface roughness of the sealing sub-parts in the assembled state, and whether there is oxide scale, etc. Generally, when the gap is large or the surface is rough, a sealant with high viscosity should be used. When the sealing area is large or the sealing surface is smooth, a low-viscosity sealant should be used. Regarding the type of the sealed medium: Full attention should be paid to the compatibility between the sealed medium and the selected sealant, that is, to ensure the stability of the chemical and physical properties of the sealant itself under working conditions, so that it can be sealed The liquids are compatible with each other. Regarding curing conditions: If you choose anaerobic adhesives, you should pay attention to whether there are conditions to be isolated from the air. If heating and complex process conditions that promote the curing of glue cannot be achieved at the work site, other types of sealants that can be at room temperature and do not need to be isolated from air should be selected. Or, control and reduce the sealing gap of the mating surface. At the same time, increase the catalyst component in the glue liquid of the anaerobic glue to shorten the curing time.
In summary, the editor of MS SEALANT FOR INDOOR DECORATION tells: a brief introduction to the selection of sealant.
