Appearance yellowish liquidQM-AA-634
Dry content[%]83.0 - 87.0QC-999-0031 (2.5h at 150°C)
Iodine color max. 15DIN 6162
*Density [g/cm³]~ 0.96 
* Miscibility:
AddWorks LXR 308 AP is miscible with most of the commonly used organic solvents, e.g. n-Butanol, Ethyl Acetate, Xylene or White Spirit. Water solubility is less than 0.01%.


Most of the solventborne clearcoats being UV stabilized with a 2:1 UVA/HALS combination, AddWorks LXR 308 AP can be a single solution replacement.

AddWorks LXR 308 AP is recommended for the following applications:

- Car refinish clearcoats
- Industrial and wood coatings
- UV curable coatings (no interaction with photoinitiators)

Recommended dosage level of AddWorks LXR 308 AP:       1.0 - 3.0% (active additive on solid resin)

Packaging and Handling

Delivery form

Steel drums 25 kg
Pallet 300 kg (12 drums)

Storage for longer than six weeks at higher temperature than +40°C can result in darkening of the additive, but this has no effect on the UV absorption capacity.
Minimum shelf life is two years from the date of shipping when properly stored in original sealed drums at room temperature under the recommended conditions.
