Huitian 4120Q Double component Silicone Potting Sealant
Product Features：
Ø Double component, condensation type.
Ø Ethyl alcohol released after curing, non-corrosive to electronic componentsØ Room temperature curing.
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, electric leakage resistance.
Ø High & low temperature resistant
Ø No need to add primer coating before use
● Main Applications：
Ø For the potting of inside and outside LED displays.
● How To Use
Ø Before use, stir component A by hand or machine properly, keep component B sealed in the bucket and shake the bucket adequately.
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
