【Features】
● This product is flowing low viscosity epoxy potting;
● can be room temperature or in temperature curing, curing rate is moderate;
● cured surface smooth and bright, no bubbles, strong adhesion;
● acid curing performance, moisture-proof water and oil dust, heat resistance and good aging properties of the atmosphere;

The scope of application
● recommended for LED flexible light strip, or need products, the role of deformation;
● can also be used for other crafts of the curved surface of the drape.
【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 10kg, which contains the main agent 5kg / pail, hardener 5kg / bucket.
