Application case of adhesive sealing for LED fountain light cover: EP 2090 transparent epoxy structural adhesive provides reliable protection solution

1、 Project Background: The Challenge of Adhesive Sealing for Fountain Lights
LED fountain lights, as an important component of landscape lighting, are widely used in outdoor humid environments such as squares, parks, and pools. They place extremely high demands on the sealing, transparency, and weather resistance of the lamp structure.

Customer demands are focused on:
The adhesive seal between the lamp cover and the plastic shell must ensure transparency and not affect the lighting effect;
The glue should have low viscosity and be suitable for automated operation through single hole dispensing;
Require the formation of high-strength, hard structure after curing, while possessing excellent waterproof and sealing performance;
Considering outdoor usage scenarios, colloids need to have stable performance such as moisture and heat resistance, pollution resistance, and weather resistance.
2、 Analysis of customer adhesive requirements
Request a detailed description of the project
The appearance transparency of the colloid should be completely transparent, and after curing, it should not affect the light emission and visual aesthetics
Moderate viscosity control with low viscosity, conducive to precise injection and automatic leveling from a single hole dispensing head
Curing method: two-component room temperature curing, with controllable operating time (about 40 minutes)
After the structural strength is cured, a strong protective layer is formed, which has the ability to resist impact and fatigue
The adhesive substrate mainly consists of PC plastic shell, glass lamp cover, metal frame and other materials
Sealed, weather resistant, long-term waterproof, corrosion-resistant, moisture resistant, and UV resistant
3、 Recommended product: EP 2090 transparent epoxy structural adhesive
To meet the above requirements, we recommend using Elaplus EP 2090 two-component transparent epoxy structural adhesive, which is a high-performance solution designed specifically for outdoor lighting and electronic sealing bonding.

✅ High transparency, does not affect the optical effect
EP 2090 forms a colorless and transparent hard protective layer after curing, which will not obstruct or discolor, perfectly preserving the optical design of the fountain lamp.
✅ Low viscosity, excellent fluidity
It can accurately dispense glue from a single hole dispensing needle, with good automatic leveling performance, suitable for automated packaging production lines, and suitable for enterprise customers with clear requirements for glue operation windows.
✅ High strength structural bonding
It has good adhesion to PC, glass, metal, plastic, and fiber materials, and forms a rigid structure after curing, which can withstand outdoor temperature differences and water pressure impacts.
✅ Strong environmental resistance
It has stable mechanical and electrical properties within the range of -50 ℃~120 ℃, is resistant to moisture and pollution, and can achieve excellent bonding without complex pretreatment, improving assembly efficiency.
✅ Environmentally friendly solvent-free
EP 2090 does not contain solvents and does not emit curing by-products, meeting environmental protection process requirements and suitable for introduction into green manufacturing factories.
The selection of adhesive and sealing materials is crucial for LED fountain lights to work in complex outdoor environments. EP 2090 transparent epoxy structural adhesive provides strong support for high-end landscape lighting products with its excellent transparency, adhesive strength, and weather resistance.
Suitable for various LED modules, car lights, camera modules, display panels and other structural components that require transparent bonding, it is a rare sealing solution for you.
