Storage
Shelf life is six months minimum when stored at 59F-68F and suitable storage environment. Like most construction materials, it must be stored in a dry, cool and well-ventilated place free from direct sunshine and other heat sources.
As it is easy to volatilize and absorb moisture, please use it up once. If not, please do keep the rest sealed right after use in order to prevent it from moisture and volatilization.

Safety & Precaution
*Please do wear rubber gloves, safty glasses and guarding clothes before application. Gloves should be changed frequently, working environment should be well-ventilated, equipments should be checked regularly and application site should be kept clean.
*polyether has slight toxicity because of the existence of low-density additives such as catalyst in it.
*The material is flammable.
*Once contacted with eyes: flush with low-pressure and clean water for at least 15 minutes and go for doctor at once.
Once contacted with skin: flush with clean water and wash with soap.
