DOWSIL™ EI-2888 - The lighting market and its challenges
Stick to the clear benefit.
Growth and impact on the planet
The global LED lighting market is expected to reach $100 billion over the next decade. This corresponds to a compound annual growth rate of over 12% in value and over 20% in volume.
Lighting-related energy consumption is expected to decline by 40% by 2030, driven by LED penetration in general lighting.
Meeting the needs of the professional lighting market
The professional LED lighting market is expected to exceed $35 billion by 2022. This includes industrial, commercial, outdoor and architectural applications.
The key growth drivers are related to expectations of:
- High efficiency
- Reliability and robustness
- High brightness
- Compact size and custom shapes
- Low energy consumption
The need for a high level of protection against intrusion
- Flexible and Rigid LED Strip Lights
- Outdoor LED Displays
- Explosion proof lighting
- Linear: Tube and Cord/Tape
- Spot, flood and general area
- Small portable type: Flashlights, portable headlamps
- Specialty and Panel
Protective materials on LEDs
- Minimal effects on luminous flux and CCT
- Challenge: Provide as little protection as possible over bare components.
- Provides the highest degree of protection and ease of use
- Challenge: Impact on the CCRS
- Better optical management
- Challenge: Lower degree of protection (air gap) and more complex impact price
Encapsulation is best suited for harsh environments, such as explosion-proof or high IP-rated fixtures.

Two rigid, high power LED modules using DOWSIL™ EI-2888 encapsulant.
Resistance of the polymerization
- Not subject to inhibition during curing
- Common problem with silicone-based encapsulants
- Insensitive to moisture during cure ≠ urethane
- No need for controlled atmosphere
- Reduced need for cleaning
Potential cost reduction
Ease of degassing
- Suitable for various mixing techniques, such as hand mixing, static mixing, dynamic mixing and centrifuging.
- No need for vacuum after application
Mix Ratio = 1:1
Flexibility and robustness
Curing time / Hardness to define your process
Stable with age
Good dielectric properties
Long service life
- Expected stability of one year
- Keep package closed - avoid moisture
- Moisture contamination reduces cure rate
