Product Features

UL certificate No. -E513688
YH-9300 A/B is a two-component epoxy system with low viscosity, good fluidity and good leveling. It has the following characteristics:
1. This product is a black epoxy potting compound with low viscosity, good fluidity and easy penetration into the gap of the product;
2. It can be cured at room temperature or medium temperature, and the curing speed is moderate;
3. No bubbles, smooth surface, high heat resistance, good gloss and high hardness after curing;

Scope of use

1. Any electronic or other products that need to be filled with sealing, encapsulation protection, insulation and moisture-proof can be used;
2. Widely used in the potting of transformers, sensors, buzzers, atomizers, negative ion generators, aquarium pumps, ignition coils, power modules, electronic controllers and other electronic components;
3. Especially recommended for priming of motor coils.

1. Weighing: In order to achieve the best performance of the product, it is recommended to use a high-precision electronic scale for accurate weighing.
2. Mixing: Mix the weighed materials A and B and stir them evenly; during manual stirring, ensure that the resin on the wall and bottom of the container is fully dispersed.
3. Pouring: Pour the mixed A and B materials into the object to be poured, and cure at room temperature or medium temperature.
4. Recommended curing process: normal temperature/12-16 hours, heating at 50-60℃, 3-4 hours, heating, +100℃/2h.
5. The more glue mixed together, the faster the reaction will be, the faster the curing speed will be, and it may be accompanied by a lot of heat, please pay attention to control
The amount of glue dispensed at one time, because due to the accelerated reaction, its usable time will also be shortened, and the mixed glue should be used up in a short time as much as possible;
6. Before using in large quantities, please try a small amount first to master the use skills of the product to avoid mistakes;
7. After filling, the glue will gradually penetrate into the gap of the product. If necessary, please carry out a second filling;
8. During the curing process, please keep the environment clean to prevent impurities or dust from falling onto the surface of the uncured glue

Please use the measured data as the standard

emergency procedures

Eye contamination from resin, hardener or mixture should be flushed immediately with clean tap water for 10 to 15 minutes. A doctor should then be consulted.Material smeared or splashed on the skin should be wiped off and the contaminated area washed and treated with a cleansing cream. In case of severe irritation or burns, consult Doctor. Contaminated clothing should be changed immediately.
