- Applications
Deuteron OG 880x is intended for use in radiation curing coatings and printing inks. They are particularly recommended for use in systems which require a thin film thickness, e.g. printing inks and overprinting lacquers. The use of Deuteron OG 880x can substantially improve coatings (ranging from silky sheen to matt) which contain silicic acid as a matting agent and possess inadequate surface resistance.
- Dosage
The optimum dosage depends on the employed binder and the required surface properties. The exact dosage should be determined by own trials. Initially an addition of 1,0 % can be used as a starting value. When a matt finish is desired, the required dosage may be relatively high (> 8 %). It must be considered whether the use of the additive will have the desired effect in systems with a high film thickness. Reason for this doubt is the poor orientation to the surface which is in turn caused by the low shrinkage or lack / evaporation of the reactive thinner. A prerequisite for use as a matting agent is that the base system possesses the necessary filmforming properties for matting. The fraction of reactive thinner (DPGDA) must be taken into account when preparing the overall formulation and calculating the UV-initiator concentration.
- Processing
Deuteron OG 880x should be incorporated into the coating system after grinding by stirrer or dissolver. High shear forces can destroy the stabilization against sedimentation. This can lead to settling if the end system was not stabilized sufficiently

Safety & Health
- Safety Regulations
According to Regulation (EC) No. 1272/2008 Deuteron OG 880x is classified as a dangerous product and therefore needs to be labeled.
Storage & Handling
- Shelf Life
- 6 Months
- Storage Conditions & Package Sizes
Deuteron OG 880x additives can be stored in their tightly-sealed original containers at room temperature for at least 6 months. Deuteron OG 880x additives may show slight serum formation (in this case enrichment of reactive thinner at the surface). This may lead to concentration shifts, among other things. Brief stirring will remedy this.
