lone-componenthigh thixotropic silica gel, this product has good adhesion and moderatestrength;
lit can be used alone or in combination with fluorescent powder for strippackaging, and will not collapse after high temperature at high temperature;
lstable opticalperformance and low light decay, improving light efficiency;
lafter curing, it can pass aging test such as cold and heat cycle impact,reflow soldering test, uv test;
l various three-dimensional shapes can be drawnby the dispenser to obtain various illumination angles, which are often usedfor the packaging of rigid led filament bulbs.
