The properties of hot melt adhesive are mainly affected by its production formula, raw material ratio, softening point, opening time, curing speed, thermal adhesion, temperature resistance and other factors. For example, the viscosity of hot melt adhesive will affect its fluidity, permeability, spraying performance, etc. The softening point affects the adhesive temperature, heat resistance and curing speed. The opening time is related to operational applicability and bonding strength.
In practical applications, users may customize specific colors of hot melt adhesives according to the needs of the appearance of the product. In order to achieve this demand, the appearance color of the hot melt adhesive is usually changed by adjusting the formula and adding color fillers without affecting the performance of the product. However, it should be noted that excessive pursuit of color effects and adding too much color filler may affect the thermal stability and other properties of hot melt adhesives.
