Solvent adhesive

Solvent adhesive is an adhesive that uses organic solvent as a dispersion medium. It is usually composed of high molecular polymers, organic solvents and various additives. Solvent adhesive has good fluidity and coating properties, and can quickly penetrate into the surface of the adherend to form a strong bond. It is widely used in leather, plastic, rubber and other industries, such as shoemaking, automotive interiors, and electronic and electrical assembly. However, the volatilization of its organic solvent will pollute the environment and pose a safety hazard. With the increasing environmental protection requirements, its development faces challenges, but it still has an irreplaceable role in some specific fields, and needs to be continuously improved in the future to reduce the impact on the environment and improve performance.

Application fields

Industrial manufacturing: In automobile manufacturing, it is used for bonding automobile interior parts, such as firmly bonding fabrics to plastics, leather to metals and other parts of different materials, and can also be used for the installation and sealing of automobile windshields. In mechanical manufacturing, it can be used for temporary fixation or repair of metal parts, which is convenient for processing and assembly.

Building decoration: In construction, it can be used to paste tiles, stones, etc., which can effectively improve the efficiency and firmness of pasting. It can also be used to seal the gaps between doors and windows, pipe interfaces, etc., to play a role in waterproofing, windproofing and sound insulation. In decoration, it can be used to paste wallpaper and wall cloth to make the decorative materials fit tightly with the wall.

Leather and shoemaking: It is a commonly used adhesive in the shoemaking industry, used for bonding the upper and the sole to ensure that the shoes are comfortable and durable. It can also be used for the repair and processing of leather products, such as reinforcing the seams of leather bags and leather clothes, repairing damaged parts, etc.

Advantages

Excellent bonding performance: It has good bonding effects on a variety of materials, and can form high-strength bonding between different materials, such as metal and plastic, rubber and glass, etc., to meet the needs of different application scenarios.

Fast drying and curing: At room temperature, organic solvents evaporate quickly, and adhesives can dry and cure quickly, which greatly shortens the time interval of bonding operations and improves production efficiency. It is especially suitable for rapid assembly processes.

Convenient construction: It has good fluidity and coating properties. It can be applied by brushing, spraying, scraping and other methods according to different construction requirements. The operation is simple and easy to master.

Good flexibility: Some solvent adhesives have good flexibility after curing, which can adapt to slight deformation of the adherend during use. It is not easy to debond due to material expansion and vibration, which improves the reliability of bonding.
