Detailed explanation of polyurethane dry composite adhesive

Polyurethane dry Composite Adhesive is a kind of high-performance adhesive, which is composed of Polyurethane Resin, curing agent, and additives. It can form a firm bond between different materials through a special dry composite process and has excellent bonding strength and weather resistance.

First, the characteristics of polyurethane dry composite adhesive

1. High bonding strength: Polyurethane dry-type composite adhesive can provide very high bonding strength and ensure that the bonded materials are closely combined and do not easily fall off or separate.

2. Good weather resistance: The adhesive has good weather resistance, can maintain stable bonding performance under various environmental conditions, and is not easily affected by environmental factors such as temperature and humidity.

3. Environmental protection: Compared with traditional solvent-based adhesives, polyurethane dry composite adhesive is more environmentally friendly, contains no harmful substances, and does not pollute the environment.

Second, the application field of polyurethane dry composite adhesive

Polyurethane dry composite adhesive is widely used in packaging, printing and other industries. In the packaging industry, it is often used to bond the packaging materials of food, medicine and other products to ensure the integrity and safety of packaging. In the printing industry, the adhesive is used to compound printing paper, plastic film and other materials to improve the durability and aesthetics of printed matter.

Third, the use of precautions

When using polyurethane dry composite adhesive, we need to pay attention to the following points: first, we must ensure that the surface of the bonded material is clean and dry to improve the bonding effect; Secondly, the proportion and construction should be carried out in strict accordance with the product description to avoid affecting the performance of the adhesive; Finally, pay attention to safety during construction and avoid contact with skin and eyes.

To sum up, polyurethane dry composite adhesive has been widely used in many industries because of its excellent bonding performance and environmental protection characteristics. With the continuous progress of science and technology and the change in market demand, it is believed that this high-performance adhesive will play a more important role in the future.
