? High & low temperature resistant
? Flame retardant rating:UL94 V-1
● Main Applications:
? For the deep potting of power supply and electronic components and parts.
? Especially suitable for the potting of inside and outside LED displays that request for flame retardant.
● How to Use
? Before use, stir component A by hand or machine properly, keep component B sealed in the can and cut a proper hole at the sharp mouth of cartridge.
? Check whether it’s adhering to Applied Materials theoretically.
? Mix component A and B with the mix ratio A: B=10:1 by weight. Beforehand simple tests are requested if you need to change the mix ratio.
? Vacuum defoaming is not necessary if the potting thickness is below 5mm,but it is requested if the thickness is more than 5mm.
? Heating curing is unsuited, or pinholes and blisters will occur.
? Long-term exposure of component B in the air is unsuited.
