Introduction to the characteristics of polyurethane sealant

Maybe many people Used polyurethane sealant, But there may not be many people who fully understand it. Polyurethane sealantisaAdhesive composed of polyurethane rubber and prepolymer, can be cured at normal temperature and heated environment. After curing, it can exert good adhesion has good properties, temperature resistance and water resistance, and has been widely used.

1. Is polyurethane sealant easy to use?

Through continuous research and development and upgrading, the quality of polyurethane sealants has been improved and its application range has become wider. It can be used in the automobile manufacturing industry, electronics industry, high-speed rail and new energy industries, and has been widely recognized. If you want to use high-quality adhesives, you can feel more at ease by cooperating with powerful suppliers, such as Shanghai Weigu, focuses on the research of polyurethane sealants. Provide customized polyurethane sealant application solutions, which are widely used and can be used in new energy, Architecture, medical care, aviation, ships, electronics, automobiles , instruments, power supplies, high-speed rail and other industries.

2. What are the characteristics of polyurethane sealant?

When the polyurethane sealant is successfully cured, it has good wear resistance and will not be easily damaged; it has good elasticity and will not be easily dented or damaged after being affected by external forces; it can be restored It has good performance. When there is a problem with a component, the local adhesive can be removed for repair, and it can still perform well after re-casting. It has a long service life, and high-quality products can be used for ten years or even longer.

3. How many types of polyurethane sealants are divided into?

Generally divided into two categories, including single-component and two-component products. Among them, single-component products are more convenient to construct and need to be cured in an environment with a certain level of moisture. The construction procedures of two-component products are slightly more complicated, but they cure faster and can perform well.

No matter what kind of polyurethane sealant it is, it has its own advantages. It is recommended that customers make a purchase based on the actual construction environment and needs to see which product is more effective. Choosing the right adhesive will help improve the quality of the project and make it safer to use.
