Glue is the LED package of high power LED package glue having a high refractive index and high transmittance can be increased flux of LED, a small viscosity, easy deaeration for potting and molding, has a good durability of the LED and reliability. LED packaging glue Features: LED encapsulation glue to add liquid silicone rubber potting compound is colorless and transparent, no low molecular weight byproducts, little stress can be deep curing, non-corrosive, easy to control cross-linked structure, small vulcanized product shrinkage Advantages; colloids can cure at room temperature, but also by heat curing; After curing gel with resistance to thermal shock, high temperature aging superior performance and resistance to ultraviolet radiation; addition, it has a low viscosity, good fluidity, easy process fast advantages. Thus, addition cure silicone is widely recognized as the power LED packaging materials an ideal, LED lens filled silicone filled silicone lens is divided into two: 1, room temperature curing type K-5508L room temperature curable gel curing conditions: 25 ℃ / 24h 2, heat curing type K-5508T heated curing gel domestic first lens can be heated rapidly solidified gel-filled, low winter temperatures suitable for emergency shipments or customer use. Curing conditions: 50 ℃ / 2-4h K-5505 silicone elastomer fast curing speed, reflow curing conditions: 100 ℃ / 1-2h two, LED module packaging plastic mold top K-5506 对 PPA materials and galvanized copper and other metal materials adhesion is good, and the PC release of the material has good curing conditions: 100 ℃ / 1h +150 ℃ / 2 ~ 4h Uses: High power LED lamp beads used, SMD LED lamp beads, integrated type modules, top mold, mold section III package, LED cofferdam plastic K-5519W Features: good thermal conductivity (thermal conductivity of 0.6), and strong bonding of metal such as aluminum, high temperature aging curing conditions: 150 ℃ / 1h Uses: LED cofferdam seal for high power SMD LED surface light source if you want to know more information, please visit (led glue http://www.rtvmifengjiao.com) Website
