Product Introduction:



? BZ-3900A/B is widely used in the potting of LED power supplies, high-power electronic components, electronic and electrical modules and circuit boards that require high heat dissipation and temperature resistance.

? The product meets the environmental protection requirements of RoHS/Reach and meets the flame retardant requirements of UL-V0 level.
?  
It's addition-curable silicone, can be cured at room temper ature or cured by heating, with good fluidity.

?  The cured colloid has excellent weather resistance and corrosion resistance, which can ensure the normal use of the lighting in a wide temperature range (-60 ~ 200 ).
