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
The 'Best use before end' date 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.
