METHOD OF APPLICATION:
It is recommended that the ambient temperature during application be greater than 15 ° C and that the adhesive should be between 65-75% air humidity and 8-10% moisture content so that the adhesive spreads to one side of the adhesive surface.
It prevents the formation of a strong bond on unwanted oil and dust surfaces and the desired strength can not be obtained.
The heat inside the glue tank should be observed and the temperature of the glue should be determined at certain intervals, especially with the weather and season changes, with the thermometer devices.
The temperature of the media and the surfaces to be adhered should be above 15 ° C.
Otherwise, the glue will not be frozen faster than the desired one and a healthy adhesion can not be obtained.
The tank should be cleaned at regular intervals.
The amount of glue applied to the surfaces may vary depending on the type of materials to be adhered. The result may be that the glue is over-applied or under-applied on the surface. It is advisable to make glue settings in such situations.
In case of interruption of working, the glue temperature is reduced by 100-110 ° C, so that the glue in the chamber does not burn and its performance continues with high efficiency.
Shelf life is 12 months at room temperature (18-20 ° C).
