【Features】
● This product is of high Globoidal Epoxy Thixotropic epoxy;
● can be ambient temperature or curing temperature, curing moderate speed;
● curable material has a higher curvature (high-only stream), high hardness, the surface smooth and bright, no bubbles, strong adhesion;
● acid curing properties were good, moisture-proof water-proof dust-proof and oil resistance, heat aging properties and good atmosphere;

【The scope 】
● applies to recommend hair ornaments, ornaments, shoe ornaments, bracelet, brooch, key chain, fashion jewelry, such as buttons, curved surface drape accessories for less demanding Globoidal products;
● other crafts can also be used for the curved surface of the drape.
【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癢痛, 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;
● packaging specifications for each of 20kg, one of the main agent containing 5kg / barrels, curing agent 5kg / bucket.
