precautions
● the product will start to solidify gradually after mixing, the viscosity will gradually increase, and will release part of the heat;
● the more glue mixed together, the faster the reaction, the faster the curing speed will be, and may be accompanied by a lot of heat, please pay attention to the control of the amount of glue, because the reaction is faster, the use of time will be shortened, the mixed liquid as soon as possible in a short time to use up;
● usable time: refers to the time of doubling the viscosity of the glue solution after mixing 100g at 25℃, not after the operational time, the glue solution must not be used;
● there are very few people for a long time to contact with the glue will produce mild skin allergy, there is a slight itching pain, it is recommended to wear protective gloves, stick to the skin please wipe with alcohol, and use detergent to clean;
● before a large number of use, please try small quantities, master the use of the product skills, so as not to make mistakes.
