Operation

1.Weigh A and B glue according to the given weight ratio into the prepared cleaned container, fully mixed the mixture again the container wall by clockwise, place it along for 3 to 5 minutes, and then it can be used.
2.Take the glue according to the usable time and dosage of mixture to avoid wasting. When thetemperature is below 15 ºC, please heat A glue to 30 ºC first and then mix it to the B glue (A glue will be thicken in low temperature ); The glue must be sealed lid after use to avoid rejection
caused by moisture absorption.
3.When the relative humidity is higher than 85%, the surface of the cured mixture will absorb moisture in the air, and form a layer of white mist in the surface, so when the relative humidity is higher than 85%, is not suitable for room temperature curing, suggest to use the heat curing.


Caution
1,The operating environment should be ventilative and should keep away from fire. Closely sealed after use.
2, Avoid eye contact, in case of contact, wash with plenty of water and get medical attention immediately.
3, If contact skin, wrap with clean cloth or paper, and wash it with water and soap. 4, Keep away from children. 5, Please take a trial before application to avoid usage mistake.

Storage And Shelf Life
1, Store at the temperature of 25°C or cool and dry place. Avoid from sunlight, high temperature or high humidity environment.
2, Use up as soon as possible when opened. It is strictly forbidden to expose to the air for a long time after it is opened to avoid affecting the quality of the products. The shelf life is six months in the room temperature of 25°C degree.
