1, Weigh Part A and Part B  according to the given weight ratio/volume 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 Part A and Part B according to the usable time and dosage of mixture to avoid wasting. When the temperature is below 15 ℃, please heat the part A to 30 ℃ first and then mix it to the Part B (Part A will be thicken in low temperature ); The lid of the RESIN and HARDENER bottle  must be sealed closely after use to avoid rejection caused by moisture absorption from the air.
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.

1,The operating environment should be ventilate 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.
