4112 RTV Silicone Potting Sealant For the deep potting of power supply and electronic components and parts.
● Product Features:
Ø Double component, condensation type.
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 retardant.
● 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. Beforehand simple tests are requested if you need to change the mix ratio.
Ø Vacuum defoaming 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.
● Packing:
Ø A: 5kg /bucket, B: 1kg/bucket.
