【Notes】 
● use, be sure to weigh accurately, and fully mixed evenly, so as to ensure uniformity of product quality. 
● This product is mixed at the start of a gradual curing, and its viscosity will gradually rise, and will release some of the heat; 
● mixed with the volume of the plastic the more the faster the reaction, curing speed will be faster and may be accompanied by a large number of heat release, please note that control the amount of time with plastic, because of reaction to speed up because of its use of time will be shortened, try a mixture of the glue used in a short time after; 
● use of time: at 25 ℃ are referring to conditions, 100g mixed viscosity of the glue to double time, it is not operational time, absolutely can not use glue; 
● there is a very small number of people will have prolonged exposure to mild liquid skin allergies, there is mild Itch, it is recommended to wear protective gloves when used, please stick to the skin with acetone or alcohol wipe and clean use of cleaning agents; 
● At the use of substantial before a small number of trial skills to master the use of products in order to avoid errors. 
【Storage and packaging 】 
● This product is to be ventilated, cool, dry place sealed preservation, shelf-life of six months, expired qualified by the trial can continue to use; 
Agent-oriented packaging specifications ● 25kg / barrel, curing agent 10kg / barrel.
