8, the use of information:
1.JX-800A-1 in the hot blast oven, preheated to about 60 ℃, add JX-800B-1 mixed mixing evenly.
2. Under vacuum conditions (50 ℃ ~ 60 ℃), the mixture is vacuumed, at the beginning, the liquid surface will rise, after the liquid level automatically drops, when the liquid surface is no longer down 10 to 20 minutes, you can stop Vacuum defoaming.
3. Potted device to 70 ℃ ~ 90 ℃ temperature pre-bake, remove the device to absorb the moisture, moisture. Preblowing time is generally required> 40min.
4. Curing temperature can be the temperature of the shell material, set the curing temperature and time, but the curing temperature shall not be less than 120 ℃.
5. After the proposed curing temperature control between 120 ℃ -135 ℃, the temperature is high when the product is likely to cause yellow.
6.HK-8001A / B self-mixing, at room temperature conditions, began to slow response, viscosity will increase with time, therefore, each amount of dosage according to the amount determined.

The above performance data is a typical data measured in a laboratory environment at a temperature of 25 ° C and a humidity of 70%. It is only for the customer's reference and does not guarantee all the data that can be reached in a particular environment. When the actual data is accurate.
