Applications
Polystyrene, self adhesive vinyl’s and coated polyesters, Rigid PVC, ABS, CAB.
NOT SUITABLE for soft PVC. E.g. Banner material. For this application we recommend the KromaFlex range of inks.
Recommendations made by Kromex are to help you match the ink to a particular job, our suggestions are to assist you and do not amount to a guarantee - Never start a print run without first doing a test print and being sure that the chosen ink matches your expectations.

Thinning
Lexac inks should be thinned using Thinner 423. For detail work and/or printing in hot conditions use Retarder 416 as part or all of the thinner. For printing Rigid PVC use Thinner 408. Lexac inks can be thinned up to 30%. If consistency needs to be retained, we recommend using up to 5% (but no more than 10% as this may affect adhesion) of Gel Retarder 436.

Coverage
The coverage and opacity achieved with Lexac inks is greatly influenced by the amount of added Thinner/Retarder, mesh used, etc.. Using a 110 T Mesh and thinning 25% an approximate coverage of 80 m2/litre may be expected.

Drying
Drying is by solvent evaporation and is influenced by the thinner used and the temperature and velocity of the air over the print.

Cleaning
We recommend Screenwash 101 or Screenwash Extra 103 for cleaning Screens and equipment. Where Health & Safety is foremost we advise the use of KromaFresh 106. A non hazardous, biodegradable screenwash that has a citrus aroma, making the workplace a better place to be. To remove any stains that may occur use KromaStain 540, a very efficient stain remover that will leave your screens looking new again.

Health & Safety
We manufacture the full range of Lexac inks to conform to EN71. We also have 9 Lead containing alternatives. Refer to separate Health & Safety sheet.
