LUMISIL® 203 UV P A/B
LUMISIL® 203 UV P is a 2-part(10:1) transparent silicone gel that is cured by UV conditions for displays. This is upgraded from LUMISIL 203 UV original to cover the curved display with the high adhesion requirement.
Properties
- Low viscosity for flowability
- Low Modulus for easy alignment
- Excellent transparency
- Low shrinkage
- Fast curing by UV
- No Oxygen inhibition
Documents
Application details
- Optical bonding for touch screen panel
- Encapsulation of optical & electronic components
- Production of damping elements
Processing
Surface preparation
All surfaces must be clean and free of contaminants that will inhibit the cure of the product.
Examples of inhibiting contaminants are sulfur-containing materials, plasticizers, urethanes, amine-containing materials, and organometallic compounds – especially organotin compounds.
If a substrate’s ability to inhibit cure is unknown, a small-scale test should be run to determine compatibility.
Mixing
Part A : Part B (ELASTOSIL® CAT UV) = 10 : 1
Curing
Curing speed can be adjusted by UV power and time.
Also heating after UV exposure can accelerate curing process.
We recommend running preliminary tests to optimize conditions for particular application.
- Recommand Lamp type: UV-A (ex. Mercury, Metal Halide etc.), 365 nm LED (If the applies lamp is 365nm LED lamp, the higher UV irradiance would be better)
Packaging & Storage
Storage
LUMISIL® 203 UV P A and ELASTOSIL CAT UV should be stored between 5 °C and 30 °C and below 60%RH in the tightly closed original container.
The 'Best use before end' date (Shelf life) of each batch appears on the product label.
Storage beyond the date specified on the label does not necessarily mean that the product is no longer usable.
In this case, however, the properties required for the intended use must be checked for quality assurance reasons.
