1、 Product description

1. 852 epoxy balance cement is divided into two parts, i.e. a and B, with epoxy resin and room temperature curing agent as the main components and filler as the main components. Component A is yellow, component B is blue or black. The mastic has good formability and thixotropy, excellent adhesion to the surface of wound coil and cast aluminum rotor, and good insulation performance (Class F, 170 ℃, rotor less than 30000 revolutions). The cement can cure quickly at room temperature.

2. 852 cement is most suitable for dynamic balance calibration of all kinds of winding and aluminum casting rotors, such as hoisting metallurgy motor, DC motor and automobile motor. In addition, it can also be used as sealing, inlaying and bonding fixing materials.

3. This product has passed SGS certification and belongs to environmental protection material. Please feel free to use it.

2、 How to use

1. The balance part of the paste to be pasted shall be clean and dry, and it can be wiped with alcohol when there is oil stain.

2. Mix a and B according to the volume ratio of 1:1 before use. At room temperature, knead with hand until the color is uniform, press the balance meter to indicate the imbalance, take out the cement, and paste it on the imbalance (inside or outside the coil end, or other parts) by hand to adjust the amount of cement until the dynamic balance is calibrated.

3. The cement pasted on the calibration dynamic balance shall be self hardening after being placed at room temperature of no less than 5 ℃ for 24 hours. No spillage during curing.

4. If the room temperature is too low and the cement is hard, it can be slightly heated to be soft by electric furnace or hair dryer. If possible, a special low-temperature oven can be prepared to heat the cement of components a and B to about 30 ℃ respectively, and then it can be kneaded for use. The glued surface shall also be properly preheated.

5. If the room temperature is too high and the clay is soft and sticky, you can rub some silica powder or talcum powder on the clay or hand and knead it.

6. When the components of a and B are mixed, the method of "repeated twist" is the most convenient.
