This product is used in many applications including the following:
These physical properties are typical but should not be considered specifications.
Typical applications include sheetfed printing on paper or paperboard substrates where matte gloss is desired. Typical gloss reading is 5-15 points with a 60° gloss meter. This is dependent on the substrate and application method. DigiGuard® UV 2250 should be evaluated in the laboratory using the actual ink system and substrate to ensure that leveling, intercoat adhesion gloss and other performance characteristics are acceptable. In general, UV coatings may not exhibit complete intercoat adhesion over some ink systems. A primer may be considered for use if this property needs to be improved.
