JRF-BM800 Waterproof isolation sealant RTV silicone rubber, has excellent resistance to cold-thermal changes, anti-stress properties, high low temperature resistance, at -60 ~ 200 ℃keep long-term elasticity and stability, anti-UV, anti-aging, and has excellent insulation, moisture resistance, shock resistance ,corona resistance, anti-leakage and chemical resistance properties. in line with the EU ROHS directive.
Application :
- high frequency head, set-top boxes bonding fixed
- moisture-proof and waterproof encapsulation of sophisticated electronic components
- LED Display module and pixel waterproof encapsulation
- suitable for small or thin layer thickness (potting generally less than 6 mm) electronic components, modules, optoelectronic display and potting protection of circuit board.
How to use :
1.cleaning : clean up the surface of an object will be potting, remove rust, dirt and grease, etc.
2.sizing : unscrew the hose cap , squeeze glue on the clean surface, make it a natural leveling.
3.curing : sealing parts be placed in the air, after the epidermis formation, and then from the surface to the internal curing process, within 24 hours (at room temperature and 55% relative humidity), silicone sealant will solidify 2 ~ 4mm depth, the curing depth increases gradually with the extension of time , due to deep curing , need for a long time, so suggest single component silicone sealant generally used for small electronic components and a thin layer potting, 6 mm thick sealant fully cured need more than 7 days .
Note: It is recommended that the thickness is thicker than 6 mm potting choose double component types .
