UV-CURING PAD PRINTING INKS TP/UV-KBASE

Produced based on UV- curing epoxy resin.

APPLICATION

UV- curing pad printing ink range TP/UV-K is a new system ofr universal applications. Due to the high quality resins contained it meets highest demands.

A variety of substrates can be printed with these pad printing inks. In addition to rigid and plasticised PVC, pre-treated polyolefines, polycarbonate and various polystyrene moditications TP/UV-K inks are also suitable for glass, paper, duroplastics and metal surfaces.

Due to the different properties of printing materials, even within the same material range, printing tests are absolutely necessary.

PROPERTIES

UV- curing pad printing inks TP/UV-K show the following properties:

l good opacity

l low tendency to yellowing

l good adhesion on different substrates

l high gloss

l adjustable flexibility

l very good transfer properties from pad to substrate (24 um plate)

l additional post-curing by heat application is possible after UV- curing

l shadow free print with good contour sharpness

COLOUR SHADES

The colour shades of the TP/UV-K range show heavy metal free pigmentation and correspond to EN71, part 3 ,safety of toys , migration of certain elements .

UXILIARY AGENTS

Pninner and adhesion promoter VH (addition up to 10%) is used to adjust viscosity to inpidual printing conditions.

ROCESSING

The following processing parameter have to be followed:

Plate:

All kinds of cliches can be used, however due to their better resistanec steel plates are preferred. Criteria for choice of p;ates are comparable to those of conventionally drying pad printing inks.

Plate depths:

Plate with an etching depth of 24 um.

Type and quality of pad:

Processing of TP/UV-K should be carried out with pads with an unworn surface (hardness 8 Shore)

UV-CURING

Pad printing inks TP/UV-K only cure under UV-radiation (approx. 2000mJ/cm²) within a wavelength of 250-410nm.

Then curing can be elerated by heat application. The chain-polymerisation caused by the UV-light will continue at roon temperature.

For difficult substrates we mend to dry at 100℃for a period of 10 minutes.

PACKING

TP/UV-K inks are available in 1 liter containers.

SHELF LIFE

For information regarding shelf life please see tin label.

Marking

Read material safety data sheets prior to processing.

The material safety data sheets ording to 91/155/EWG contain marking to compliance with the regulation on dangerous working materials as well as instructions for precautions when processing, handing and storing as well as first aid .

The information given in the material safety data sheet refers to processing as described in this technical leaflet .
