Comparative Properties of Optically Clear Epoxy Encapsulants Refractive Index ( IR ) is the ratio of speed of light in that media vs the speed of light in air Rayleigh scattering (losses) occur when light passes from one media to another with a different refractive index
Understanding Optical Properties for Epoxy Applications Index of Refraction (sometimes referred to as Refractive Index) is the measurement of the speed of light within a certain substance The value itself is expressed as the ratio of the speed of light in a vacuum relative to the speed of light in the specific medium
Cycloaliphatic Epoxy Materials Datasheet - The Gund Company Cycloaliphatic Epoxy is a low viscosity, low molecular weight, epoxy resin designed for high voltage outdoor electrical applications The epoxy resin system achieves crack free components with excellent mechanical and electrical properties with high uniformity
Cycloaliphatic epoxy oligosiloxanederived hybrid materials for a . . . The cycloali-phatic epoxy hybrimers have a high-refractive index of over 1 56 without reference to their compositions due to the presence of many phenyl groups 8 In par-ticular, the cycloaliphatic epoxy hybrimer with TPS of 33 3 mol % shows a high-refractive index of over 1 58 at 632 8 nm
Cycloaliphatic vs Traditional Epoxy Resins: Properties Applications . . . Cycloaliphatic epoxy resin is distinguished by its unique chemical structure that does not contain aromatic rings Instead, its molecules are formed with cycloaliphatic rings, which contribute significantly to its superior properties
Understanding Cycloaliphatic Epoxy Resins and Application Cycloaliphatic epoxy resins have higher reactivity to anhydrides compared to amines The specialty epoxy resins can fully cure in an anhydride system, avoiding the use of highly toxic and volatile amine curing agents, making it safer for operators
Journal of Applied Polymer Science | Wiley Online Library Cycloaliphatic epoxy hybrimers with 2 mm thickness fabricated by thermal curing of cycloaliphatic epoxy oligosiloxane resins with a hardener and catalyst were optically transparent (∼90%) with a high refractive index of up to 1 583
