DCL INK
INTRODUCTIONS
DCL INK with gloss finish has superior weathering resistance.
DCL is designed for the applications that need excellent weathering resistance such as automobile sticker. Weathering resistance and gloss are even more improved with DCL , OCC.
APPLICATIONS
Printing on weathering resistant vinyl sticker , Vinyl-chloride-resin-decorative steel sheet , flexible vinyl , rigid vinyl, ABS , polycarbonate , PVC
CHARACTERISTICS
– Superb weathering resistance (SWOM > 300H outdoor exposure > 2 years
– Clogging is hard to happen and printability is excellent.
– Excellent resistance to alcohol , gasoline , oil and chemicals.
– Flexible and blocking-resistant.
– Harmful substances such as heavy metal are not Contained.
HOW TO USE
Dilute the ink with PC thinner (slow drying , retarder , special retarder). Use Vinyl Cleaning Thinner for washing up. 150-250 meshes/inch is recommended.
XN-14710 (KAI) : Hardener JA-950 = 100:25 is mixing ratio. Dilute the mixture with PC thinner (slow drying , retarder , special retarder). Use Vinyl Cleaning Thinner for washing up. 150-250 meshes/inch is recommended.
Pot life of the mixture is 3-4 hours at 20 degrees Celsius.
Drying
Ink dries at room temperature although drying time varies depending on the substrate.
Ex. Complete drying time when diluted with PC thinner standard drying by 20% (room temp. 20 degrees Celsius)
vinyl sticker , flexible vinyl : 10-20 min.
polycarbonate , rigid vinyl : 20-60 min.
Drying time is shortened by forced drying such as with the jet dryer.
Heat drying conditions are 80 degrees Celsius x 60 min. Ink almost dries at room temperature after 24 hours , but drying completes after 3-4 days. The properties obtained at room temperature are inferior to what obtained with heat drying.
Weathering Resistance
7-8 grade. Please refer to “Lightfastness List ” for the information of each color.
Color Range and Type of Packing
standard 14 colors , XN-14710 (KAI) 1-kg-can
Precautions
Please refer to MSDS before use.
Properties
Three hits on polycarbonate
Printing sequence : 38 red → 90 black → super white
Diluted with PC thinner standard drying , polyester 225 meshes/inch

Notes
1) The information given here is based on our laboratory testing and is no guarantee.
2) Weathering resistance remarkably changes depending on the ink thickness and how the printed matter is used. The above information is obtained with dark color. The properties of pale color are inferior to those of dark color.
