Process of use

Preheating: Please bake the poured device at 70~80℃ for 1~2 hours, which can also reduce the temperature and extend the heating time to remove the moisture of the device. Bepu 6603 at low temperature, the viscosity will become high, can preheat the material to 25℃~45℃ for easy use.

Mixing: Stir well in the original package of A, and then weigh. Weigh A and B materials in proportion, stir vertically with the mixing rod, and stir clockwise (or counterclockwise) in the same direction for 2 to 3 minutes to minimize the mixing of air. Pay attention to the bottom of the container, the edge of the part should also be stirred evenly, otherwise there will be local non-curing phenomenon.

Defoaming: For those who require smooth and no bubbles on the potting surface, the mixture should be vacuumed (≤-0.1mpa) to remove bubbles. Stirring while vacuuming dynamic debubbling, more conducive to the removal of bubbles. If mechanical metering is used for mixed potting, steps 2 and 3 are omitted.

Pouring: Pour the mixture into the device, the device structure is complex, large volume, should be divided pouring. The pouring bubbles can be blown with a hot air gun. Surface bubbles can be eliminated.

Curing: 25℃/24h or 80℃/1h can be cured. The ambient humidity should be controlled at <70%, and the curing time should be extended when the temperature is low.

In the case of insufficient curing time or low room temperature environment, the surface will be sticky the next day is normal, and it will gradually disappear after a few days.

The curing condition of potting glue is affected by temperature and glue amount, high temperature is short curing time, more glue amount is fast curing speed, and vice versa.
Unused raw materials should be stored in a well-sealed bucket to avoid moisture intrusion and affect the quality of raw materials. The opened materials should be kept sealed and used up as soon as possible.

It is recommended to store in a cool area, away from direct sunlight;

Storage temperature: 10-30℃, A material storage period of 12 months; Material B is 6 months.
As a manufacturer, we would like to share with you what we have learned about the different types of potting compounds and their characteristics.
The potting compounds on the market vary in viscosity, requirements for cure conditions, among other factors. Compounds such as polyurethane, silicone, and epoxy are widely used in a variety of applications.
Silicone Potting Compounds are soft and flexible, silicone potting compounds and encapsulating materials possess a good level of elongation.Silicone potting compound can also withstand a wide range of temperatures. Most silicone materials are able to operate at temperatures between -40°C and 200°C.
Epoxy potting compounds generally perform as a better adhesive, high-temperature resistance, and chemical resistance and have better adhesion to a wide variety of substrates and typically do not need primers.
Polyurethane Potting Compounds generally have better flexibility, elongation, and abrasion resistance.
Acrylic Potting Compounds are UV and heat-hardening materials, with fast hardening, adequate chemical resistance, and clear appearance.
