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 the
temperature is below 15 ℃, please heat A glue to 30 ℃ 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.
