LED compatible adhesives need high chemical tolerance that makes them resistant to yellowing, and they need to withstand high or low temperatures while still maintaining a strong seal. DELO Industrial Adhesives recently released 14 new adhesives that are compatible with LED lighting. Ten of these are intended for direct contact with LED lights while the other four are used for applications where contact is indirect.
The adhesives are all light-curing epoxy resins that have outperformed silicones, both in terms of stability and curing time. In addition the epoxies are better able to exclude moisture – an important consideration in optimizing the lifespan of LED lighting. The adhesives are used to mount reflectors or lenses and to seal LED lights into housings. They are ideal for use in LEDs found in automotive, outdoor, residential, industrial and commercial lighting applications. The sealing properties of adhesives makes them a better choice than screws or plugs, allowing for a longer service life while maintaining optical quality.
