— From potting to optics, from sealing to thermal conductivity, one set of adhesive solves the reliability issues of LEDs. In LED lighting and display applications, brightness, lifespan, and stability are never determined by a single factor.
Temperature rise, moisture, mechanical stress, and optical attenuation are often the key factors determining how long and stably an LED can illuminate.
Behind these issues, the selection and matching of adhesives are becoming an indispensable part of LED reliability design.
Focusing on the core application scenarios of LEDs, ELAPLUS provides a complete and mature LED adhesive application solution 👇
I. LED encapsulation protection – SIPC 1816 creates a long-term stable “protective layer” for the internal circuit of LEDs. In structures such as LED driver power supplies, modules, and light bars, internal components are exposed to high temperatures, humidity, and electrical stress for extended periods, making them highly susceptible to issues such as insulation degradation and solder joint failure.
LED encapsulation LED encapsulation SIPC 1816 silicone encapsulant, specifically designed for LED electronic encapsulation:
Application value:
The overall protection provided to PCBs and electronic components significantly enhances the moisture resistance, dust resistance, and insulation performance of the LED system. It also cushions the mechanical stress caused by thermal expansion and contraction, reducing the risk of cracking. Core advantages:
Low stress and low shrinkage, suitable for precise LED electronic structures with good fluidity, no dead spaces in potting, minimal bubbles, long-term resistance to high and low temperatures, suitable for outdoor and high-power LED applications. 📌 Typical applications: LED driver power supplies, LED modules, power control board potting
II. LED Optical Packaging – SIPA 1840 High Transparency, Only Deserving of High-Brightness LED Displays. In the LED optical structure, the encapsulant is not only a “fixing material”, but also a part of the optical system.
Insufficient light transmittance, yellowing, and light decay will all directly affect the final luminous efficiency performance.
SIPA 1840 optical-grade silicone rubber, dedicated to LED optical applications:
Application value:
Guarantee the light output efficiency of LED chips, reduce light loss and color temperature drift, and enhance overall luminance consistency. Core advantages:
High light transmittance, low haze, excellent UV resistance and anti-yellowing performance without absorbing light. Its optical performance remains stable even under long-term high-temperature operation. 📌 Typical applications: LED packaging, lens bonding, optical protective layer

Elevated waterproof bonding for Elevated waterproof bonding for Elevated waterproof bonding for outdoor lighting, industrial lighting, and landscape lights, the requirements for protection levels are becoming increasingly stringent.
Once water vapor intrudes, at the very least, the lighting fixtures will fail; at worst, the entire lamp will be scrapped.
SIPC 1859 silicone sealant, tailored for LED lighting structures:
Application value:
Achieving reliable sealing of the lamp housing, interfaces, and gaps effectively enhances the protection level (such as IP67/IP68). Core advantages:
Excellent waterproof and moisture-proof performance, good elasticity, adaptability to material thermal expansion and contraction, strong weather resistance, no pulverization or peeling after long-term outdoor use 📌 Typical applications: LED lamp housing sealing, joint waterproofing, interface sealing

If heat cannot be dissipated in a timely manner, light decay, color drift, and a decrease in lifespan are almost inevitable.
SIGR 2225 thermal grease, dedicated to LED heat dissipation management:
Application value:
Rapidly dissipate the heat from the chip to reduce junction temperature, extend the lifespan of the LED, and enhance the operational stability of the system. Core advantages:
High thermal conductivity, low thermal resistance, good coating performance, fully filling microscopic gaps, no drying or cracking, no loss after long-term use. 📌 Typical applications: thermal interface filling between LED chips and heat sinks
Check the details of SIGR 2225 thermal grease. LED reliability upgrades begin with “choosing the right adhesive”. From internal potting protection to optical packaging; from structural sealing to efficient thermal conductivity – adhesives are no longer just “auxiliary materials”, but a part of LED performance.
SIPC 1816 / SIPA 1840 / SIPC 1859 / SIGR 2225 together constitute a complete, professional, and practical LED adhesive application solution, which helps LED products achieve comprehensive upgrades in brightness, lifespan, and reliability.
