The most common colors of hot melt adhesives we know are white, white transparent, yellow, black, yellow transparent, and milky white, which can be used in different industries and fields. The different colors of hot melt adhesive not only meet the user's requirements for color, but also have a certain impact on its appearance in terms of raw materials. The color difference has nothing to do with the quality of hot melt adhesive.

The different proportions of raw materials in the production formula of hot melt adhesive have a significant impact on its viscosity, curing point, and other properties. If the hot melt adhesive does not undergo oxidation, deterioration, or color requirements, it is generally white, transparent, yellow, or yellow transparent, which are several common colors. When all raw materials are mixed and processed together in the production of hot melt adhesive, chemical reactions will occur, which determines the performance of the hot melt adhesive, At the same time, it also leads to color changes after the production of hot melt adhesive. So can the color of hot melt adhesive determine its performance? This statement is definitely not valid.

At present, with the widespread application of hot melt adhesive, although the conventional color of hot melt adhesive is a common choice, there are also many customers who need to customize special colors to consider the impact of their own product appearance. Therefore, hot melt adhesive manufacturers will add color filling to the formula to change the appearance color of the hot melt adhesive without affecting product performance. Of course, it should be noted that excessive color fillers should not be added in pursuit of good appearance, as this can affect the thermal stability of hot melt adhesives and can easily cause problems during use.

Some people used to say that transparent hot melt adhesives have better performance and viscosity than opaque ones, but this statement ignores the formula issue. As long as the formula is good and the raw material ratio is reasonable and correct, no matter what color it is, it will not affect the performance.
