Hot-melt adhesive is an environment-friendly and easy-to-operate adhesive, and it is favored because of its advantages of easy use, high adhesive strength and fast adhesive speed. Hot-melt adhesive is commonly used in packing boxes, shoe materials, leather, cotton cloth and electronic products. Hot-melt adhesive has yellow, light yellow, white, translucent and fully transparent colors. With the continuous progress and development of social level, White, translucent and transparent hot-melt adhesives are in increasing demand and can be used in various products. However, white hot-melt adhesives produced by many manufacturers tend to be yellow and dull. At this time, it is necessary to increase the whiteness and brightness of hot-melt adhesives with special fluorescent whitening agents.

Manufacturers often modify the existing hot melt adhesives by some methods to improve the properties of hot melt adhesives and meet the needs of different users. For example, stabilizers can be used to prevent oxidation; Adhesives can improve the bonding strength; Paraffin wax can reduce viscosity and change surface properties; Various fillers can improve viscosity, melting point and adhesive strength. Special fluorescent whitening agent for hot melt adhesive can increase the whiteness and brightness of hot melt adhesive and improve the appearance characteristics of products. So there are many types of fluorescent whitening agents, which one is suitable for hot melt adhesives? The fluorescent whitening agent OB produced by our company is a special whitening agent for hot melt adhesives, which is developed and produced according to the characteristics of hot melt adhesives.
