"Hot melts" is the name given to the thermoplastic adhesives, solid at room temperature, and which can be applied liquid (melt) by means of heat. These materials stick strongly on the work surface, while they cool down under their melting point. Unlike liquid adhesives, hot melts are applied without using chemical reactions or solvent evaporation, thus leading to important environmental benefits.

Since they can be handled and stored in the solid state, the use of hot melts enables to optimize both the logistics and transport processes. The almost instantaneous union strength provided by hot melts has contributed to the development of faster and more productive machinery Their higher viscosity, compared to that of solvent based adhesives, enables their utilization in porous and non porous surfaces without sacrificing the union strength.

In our days, hot melts are an essential part of productive activities. With the development of manufacturing processes and equipment that operate at great scale and high speeds, hot melts are found in a wide variety of applications, from furniture and shoes to diapers or cigarettes manufacturing.

Waxes play an outstanding role in the production, processing and performance of hot melts. All wax products developed by Multiceras, specifically for this application, are crystalline by nature and their properties enable to decrease the adhesive viscosity, as well as a precise control of open time, flexibility and elongation.

The most suitable wax is selected in function of its compatibility with the resins and polymers utilized in the formulation, as well as in function of the final specifications of the adhesive material to be produced. Waxes constitute up to 70% of the total hot melt formulation, depending on the application form and on the required hot melt properties.
