● casting products to the need to maintain dry, clean;
● Please check the A agent when used to observe whether there is settlement, and agent A, stir;
● Press the ratio of the amount taken, and the weighing accuracy, please remember that the ratio is the ratio of weight rather than volume, A, B agent to be mixed, stir in order to avoid incomplete cure;
● Stir the filling plastic please, and try to use the time you are finished using the glue has been mixed;
● perfusion, glue products will gradually penetrate into the gap, if necessary a second plastic irrigation;
● curing process, please keep the environment clean, to prevent impurities or dust into the surface of uncured glue.

【Note】
● use, please be sure to weigh accurately and fully stirred to ensure uniformity of product quality.
● The product began after the curing mixture, its viscosity will gradually increase, and will release some of the heat;
● glue mixed with the more the faster the reaction, curing speed will be faster, and may be accompanied by a lot of heat release, please pay attention to controlling the amount of time with plastic, because the reaction to speed up its time use also shortened the glue mixture used up as much as possible in a short time;
● use of time: is the condition at 25 ℃, 100g mixed viscosity glue after doubling time, not operational time, the glue should never be used;
● a handful of people will have prolonged exposure to glue mild skin irritation, mild itching, wearing protective gloves is recommended, please stick to the skin, wipe with acetone or alcohol, and use detergent;
● in a large number before you use a small amount of trial skills to master the use of products in order to avoid errors.
Storage and packaging】 【
● This product must be in a ventilated, cool, dry place sealed, shelf life of six months, expires by the pilot qualified to continue to use;
● Package size for each group of 36kg, which contains the main agent 25kg / barrel, curing agent 10kg / barrel.
