Bicomponent 3301A 3301B agent agent
Features:
1, the product is black electronic potting room temperature curing epoxy, low viscosity, good fluidity, easy to penetrate into the gap in the product;
2, room temperature or medium temperature curing, curing rate is moderate;
3, no bubbles after curing, the surface smooth, has good gloss, high hardness;
4, curing a flame retardant, acid properties, and moisture properties of good water and oil dust, heat and humidity and atmospheric aging;
5, cured with good insulation, compressive strength, high bonding strength of electrical and physical characteristics.
Scope:
1, where the need for infusion sealed package protection, insulation or other proof of electronic products can be used;
2, is widely used in transformers, AC capacitors, ignition coil, negative ion generator, aquarium water pumps, ignition coils, power modules, electronic controllers and other electronic components of the casting;
3, does not apply to flexible or soft shell encapsulating products.

Curing condition: room temperature 6-8 hours or 60 ℃ × 1 小时
1, the product needs to be kept dry potting and clean;
2, please check the A agent when used to observe whether there is settlement, and agent A, stir;
3, according to the ratio for quantity, 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;
4 Stir the filling plastic please, and try to use the time you are finished using the glue has been mixed;
5, perfusion, glue products will gradually penetrate into the gap, if necessary a second plastic irrigation;
6, the curing process, please keep the environment clean, to prevent impurities or dust into the surface of uncured glue.

Note:
1, the goods began after the curing mixture, its viscosity will gradually increase, and will release some of the heat;
2, mixed together, the more glue, and its response to the faster curing rate 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, which can be used time will be shortened as much as possible the mixture of glue used up in a short time;
3, use of time: is the condition at 25 ℃, 100g mixed viscosity of the glue after the doubling time, not operational time, the glue should never be used;
4, 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;
5, 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:
1, the goods to be ventilated, cool, dry place sealed, shelf life of six months, expires by the pilot qualified to continue to use;
2, packing specifications for each of 30kg, which contains the main agent 25kg / barrel, curing agent 5kg / bucket.
