thermal paste compound,
silicone thermal grease
·4120Q, which is a condensed 2-part silicone sealant and can cure at room temperature, is suitable for molding intricate electronic parts as its low viscosity.
·Otherwise ,it is non-corrosive and suitable for adhering many substrates.
·Suitable for molding intricate electronic parts because of its low viscosity.
·Excellent impact resistance because it forms an elastic silicone rubber after curing.
·Excellent heat resistance, damp resistance and freezing resistance.
·Non- corrosion to the substrate as it is dialcohol curing type.
·Excellent adhesion to many substrates without primer ,especially to PC and Epoxy.
·The fixation and the insulation of the electronic parts.
·Damp-resistance and water resistance for electronic parts and PCB boards.
·Potting of LED displays.
·Other general insulation molding.
â HOW TO USE
·Before mixing, part A should be stirred adequately in container ,and part B should be shaken well in container.
·Before application, you should confirm that its adhesion to
the substrate is well.
·Generally, the mixing ratio of part A and part B is 10 : 1.
If you want to change the curing conditions, a simple test is necessary before used .The curing time and pot life will be decreased while the amount of part B increasing.
·The extra bubble removal is not necessary when molding depth is less than 5 mm. Otherwise , it should be vacuumized at 10mmHg for at least 5 minutes to remove the bubbles. Otherwise, it will influence the surface appearance.
