2-Part Epoxy resinPotting Compound（Black, White, Clear、Red）
Epoxy sealant is a high-strength, superior electrical performance, and high surface gloss adhesive formed by mixing epoxy resin and curing agent. This sealing adhesive can cure at room temperature and has characteristics such as high transparency, high adhesion, waterproofing, high temperature resistance, and corrosion resistance. Widely used in electronic and electrical equipment, it has strong structural support and mechanical protection capabilities after curing. Due to its relatively low price, it is widely used in the automotive industry, consumer electronics components, wind power equipment, aerospace and other fields to enhance the mechanical structural stability and performance stability of these components in harsh environments.

- Mix the glue: the glue componentin the original packaging after the full mixing (no filler can not stir), the A and B components according to the provisions of the quality ratio of mixing (see the table above the mixing ratio), stir even after potting, The time available after mixing is shown in the table above. More than the available time, glue viscosity will be high, no longer suitable for perfusion. So each time with the amount of plastic should not be too much, otherwise it will cause a waste.
Curing:Cure conditions See table above. Curing speed and temperature-related, high temperature fast curing, winter temperature is low, curing time will be extended, a variety of plastic can be used curing curing method, at 80 ℃ under the conditions of curing 2 to 3 hours. After the hardening of the glue can be assembled, the test generally need to cure 24 to 48 hours after the.
OPERATION PRECAUTION
1. Beforeusingthe A component of the compound must be in the original packaging to stir evenly (because the long-term placement may be precipitation, stirring even after use, does not affect performance).
2. Different seasons due to temperature changes in curing speed is different is normal, the wintertemperature is low curing will be slower. Above all kinds of plastic can be used heating curing method.
3.Some of theA, B components of the colloid in the low temperature conditionsmay occur crystallization, agglomeration, which is normal; before use it can be placed in the oven at 80 ℃ to melt, and then put to room temperature after use Does not affect its performance.
4.In the mixing process, pay attention to the inner wall of the container mustbe folded back to the mixing, to ensure the uniformity of plastic. Curing time is affected by temperature, winter can choose to use JOME winter formula.
