Customized POLYURETHANE SEALANT FOR CONSTRUCTION from China manufacturer is widely used and has good performance characteristics. It can be prepared to provide various physical properties, such as viscosity, construction performance and service life. Polyurethane systems used in adhesives can be divided into two categories, namely 1K (one part) and 2K (two parts). Customized POLYURETHANE SEALANT FOR CONSTRUCTION from China manufacturer has some similarities, and each has its advantages and disadvantages.

Both types of customized POLYURETHANE SEALANT FOR CONSTRUCTION from China manufacturer have some advantages and limitations. These advantages include the curing time, the ability to change the coating time by changing the formula, and good solvent resistance after curing. According to different formulations, the cost of customized POLYURETHANE SEALANT FOR CONSTRUCTION from China manufacturer is also moderate. It can be used in a variety of coating methods, such as roll coating, brush coating and spraying, which can be carried out manually or automatically.

Customized POLYURETHANE SEALANT FOR CONSTRUCTION from China manufacturer is also non flammable and has excellent adhesion to a variety of substrates.

Another advantage is that good flexibility can be obtained in the cured product without the heat required for curing, but once there are two substrates, they can be used to speed up the curing speed. They also maintain adhesion over a wide operating temperature range.

At the same time, customized POLYURETHANE SEALANT FOR CONSTRUCTION from China manufacturer still has some limitations. These include uncured materials sensitive to moisture and short shelf life. Although they adhere to most substrates, some substrates may require primer to adhere to polyurethane base adhesive. Since the formation of carbon dioxide can cause foam, components made of polyurethane adhesive may also need to remain in the press under sufficient pressure while the adhesive solidifies to prevent this.

1K adhesive has some other advantages due to its supply mode and the formation of urea bond during curing. These measures include no mixing, ease of use, excellent chemical resistance and the ability to use or not use solvents, depending on the situation required.

1K adhesive has some other advantages due to its supply mode and the formation of urea bond during curing. These measures include no mixing, ease of use, excellent chemical resistance and the ability to use solvents or solvent-free according to the desired use.

In addition, the most common problems of customized POLYURETHANE SEALANT FOR CONSTRUCTION from China manufacturer are usually due to one of the following reasons. First, use adhesives with a short service life, as this will prevent the assembly of the substrate and withstand pressure during the service life. In addition, when there is not enough adhesive applied to the substrate, the coverage is not sufficient to provide complete adhesion. If one of the substrates is porous, it must be taken into account, as should the uniformity of the surface. Finally, if the pressure inside the printer is insufficient, there will be problems. The total surface area of the substrate needs to be considered, so the pressure is about 10Pa.
