High refractive index LED package silicone gel IOTA 4011 Description: IOTA 4011 dedicated to high-power LED device package and is ideal for the production of high-power LED packages with a high refractive index, high transmittance, high flexibility and good resistance to UV aging properties, suitable for high-power LED and SMD LED encapsulants and Lens filling. Applications: High refractive index LED package of silicone gel is durable dielectric insulator, in extreme operating conditions, it can play the role of a barrier against environmental contaminants High refractive index LED package of silicone gel is particularly suitable for use in an electronic component package, can provide protection from extreme temperatures, radiation, thermal and mechanical stress; High refractive index LED package of silicone gel has a low ionic content and a high transmittance for light of the LED package; As a low-viscosity, high-performance products, but also especially suitable for high-speed electronic component production requirements (high flow performance) program; Physical and chemical indicators: Before solidifying performance IOTA-4011A IOTA-4011B Appearance Colorless Colorless Viscosity (mPa.s) 12500 750 Mix Ratio by weight 1:1 Viscosity (mPa.s) 1800 Before solidifying performance（solidify condition：100oC 1h +150oC 4h） Hardness（Shore D） 30 Tensile Strength（MPa） 4.1 Elongation（%） 95 Refractive Index 1.54 Transmittance（%）450nm 95 (2mm) How to use: 1. According to usage, accurately weigh a certain weight ( equal weight component A and component B); 2. The A, B two components are mixed in a dry container, stir standing defoaming or vacuum to remove air bubbles; 3. To be packed components should be cleaned, dried, mixed silicone and pour it completely infiltrated; 4. Place the packaged chip oven to solidify. solidifying speed can be changed by changing the temperature, recommended conditions: first cured 1h at 100 ℃, 4h and then cured at 150 ℃. Note: 1. LED package Silicone gel IOTA 4011 is non-dangerous goods, according to general chemical transport; 2. Store the product in a cool dry place, shelf life is six months; A, B components are required to be sealed, same requirement after opening , avoid contact with moisture in the air, before the package should be kept dry LED chip Do not touch the product of nitrogen, phosphorus, sulfur, ethynyl, more vinyl, peroxide and lead, tin, cadmium and other metal compounds, to avoid catalyst poisoning affect the solidifying effect. Package: IOTA-4011 A: 500g IOTA-4011 B: 500g Tips: The information obtained here from our understanding and practical applications in the laboratory, with a certain reference. However, due to the conditions and methods of use of the product are beyond our control, be sure to carry out testing and evaluation before use.
