Permaset Print Retarder Updated

Permaset Print Retarder is designed to slow the drying of Permaset and other screen printing inks. Retarded drying serves to increase open time and reduces drying in or clogging of the screen, particularly with fine meshes and in low humidity environments.

Permaset Print Retarder also improves release of both ink from the screen and screen from the print.

The extra time required to dry the print will depend upon the amount of Permaset Print Retarder added to the ink as well as local factors such as heating capacity, air movement, humidity and moisture content in the base fabric. Usually, adding 10-20% extra drying time will suffice in drying the wet print. Once thoroughly dry, prints should need no extra time for curing the print. However, they will require extra time to become touch-dry.

Incomplete removal of Permaset Print Retarder from the printed ink during the drying process can:

1) with textile products, compromise early wash resistance and

2) in paper or other flat stock products, increase the tendency to block.

It is imperative that prints be thoroughly dried and cured, before washing in the case of textiles or stacking and/or rolling in the case of paper stock. With textiles, it is strongly recommended that test samples be washed to assess effectiveness of the drying and curing regime employed.
