25 Kg Paper Bag
 

Shelf life:

Shelf life is 12 months at room temperature  (18-20 °C).

 

Recommendations:

On undesirable oil and dust surfaces, it prevents  the formation of a strong bond and the desired  strength cannot be obtained.

The temperature inside the adhesive thank  should be considered, and be controlled  frequently due to changes in weather &  conditions. During season changes adhesive  temperature must be measured by thermometer  devices.
The temperature of the application surface and  environment must be higher than 15ºC Otherwise, successful results cannot be achieved  due to faster drying time.

Adhesive tank should be cleaned frequently.  The amount of the adhesive, which is applied on  the surfaces, can vary due to type of the  materials. Some undesired results may occur  such as over usage and inadequate usage. In  these cases, glue setting should be applied.

In case of giving a pause, adhesive temperature  must be binded at 100-110°C to keep  performance higher and a prevent glue from  burning.
