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.
