Product Description
OPTOLINQ TMC-8020-LS is a high-performance optical solid epoxy specifically developed for LED encapsulation. This monocomponent epoxy achieves superior adhesion performance and great transmittance. It has lower Tg than the "normal" 8020 version.
OPTOLINQ TMC-8020-LS is able to offer low blue-ray decay for outdoor LED applications and overall great light performance. This low stress white epoxy is very close to competitive solutions such as XX814, XX1000 and XX97. It is a reliable product that has improved reflow abilities and thermal shock test performance.
