Ø Room temperature curing.
Ø Ethyl alcohol released after curing, non-corrosive to electronic components
Ø High adhesion to all electronic components except for those made of PP&PE.
Ø High performance on insulation, damp proofing, vibration resistance, chemical resistance, electricleakage resistance.
Ø No need to add primer coating before use
Ø High & low temperature resistant
Ø Flame retardant rating:UL94 V-1
● Main Applications:
Ø For the deep potting of power supply and electronic components and parts.
Ø Especially suitable for the potting of inside and outside LED displays that request for flame resistant
● How to Use
Ø 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.
Ø Check whether it’s adhering to Applied Materials theoretically.
Ø Mix component A and B with the mix ratio A: B=10:1 by weight. Before hand simple tests are requested if you need to change the mix ratio.
Ø Vacuum deforming is not necessary if the potting thickness is below 5mm, but it is requested if the thickness is more than 5mm.
Ø Heating curing is unsuited, or pinholes and blisters will occur.
Ø Long-term exposure of component B in the air is unsuited.
