With the rapid development of LED lighting technology, LED rigid strips have been widely used in commercial lighting, display light boxes, outdoor advertising, car light modules, and other fields. It has the advantages of high brightness, long lifespan, and energy-saving stability. However, in long-term use, the moisture, dust, corrosion, and mechanical impact protection of LED hard light strips become key challenges.
In this application context, choosing a suitable LED hard light strip sealing adhesive can not only effectively improve product protection performance, but also extend service life, improve light quality and overall reliability.
This article will introduce the typical application and performance advantages of Elaplus EP 1708 (7 #) transparent epoxy sealant in LED hard light strips.
1、 The necessity of LED hard light strip encapsulation
LED hard light strips are usually composed of aluminum substrates, LED beads, resistors, capacitors, and other components, which are highly susceptible to external environmental influences when exposed to air.
The main reasons for its failure include:
Moisture infiltration leads to short circuit or blackening of the circuit;
Dust and oil pollution adhesion affect heat dissipation and light efficiency;
Long term illumination leads to thermal stress cracking;
Solvent and chemical erosion of component solder joints.
Therefore, using transparent epoxy sealant for overall sealing and encapsulation can not only effectively isolate moisture and pollutants, but also provide structural support and electrical insulation protection for the light strip.
2、 Glue requirements
The LED hard light strip sealant needs to meet the following performance requirements simultaneously:
High transparency: ensuring that light efficiency is not affected;
Strong yellowing resistance: no yellowing or turbidity after prolonged illumination;
Good electrical insulation: prevents short circuit or arc breakdown;
High and low temperature resistance: stable in environments ranging from -40 ° C to 100 ° C;
Strong adhesion and no cracking: Good adhesion to aluminum substrates, plastic lampshades, and PCBs;
Easy to construct, high curing efficiency: suitable for automated production or room temperature curing processes.
3、 Recommended product: EP 1708 (7 #) transparent epoxy sealant
Yilian EP 1708 (7 #) is a two-component epoxy resin potting adhesive that can be cured at room temperature or temperature. It is designed specifically for the protection and sealing of electronic components, and is particularly suitable for transparent potting of LED hard light strips, light strip modules, outdoor lighting fixtures, sensors, and electronic display screens.
Product Features
Transparent appearance: After curing, a clear and transparent protective layer is formed, which does not affect the LED’s light output;
Moisture and dirt resistance: effectively resist moisture, dirt, and other atmospheric pollutants;
