Description

Curable reducer can be added to any Excalibur Phthalate-Free Plastisol ink to not only drop the viscosity but also help improve the flow of the ink and help the ink clean completely from the screen mesh.

Even though it can be used in any quantity there are some precautions when mixing 501PF Curable Reducer into Excalibur Plastisol ink. Please refer to the resources tab to see the Notes On Using Curable Reducer for more information.

Another benefit of adding 501 Curable Reducer is that it softens the “hand” of the final print. Experimenting with the addition of 501 Curable Reducer in different percentages can be beneficial in balancing the “feel” versus the opacity requirements of the particular job.

Notes on Using Curable Reducer

1. Always stir the ink thoroughly prior to adding to the screen in order to break down any false body that builds up during storage. This should always be done prior to adding 501PF Curable Reducer to any ink. If using an ink paddle with a variable speed drill always set drill to turn on a slow speed to not allow any heat from the friction of stirring to build up in the ink. Introducing heat to the ink will begin the gelling process and make the ink more difficult to print.

2. Adding too much 501PF Curable Reducer will diminish opacity particularly when printing a high-opacity ink onto dark backgrounds. For this reason best results are attained by adding no more than 3-5% of 501PF by weight to any high-opacity ink that is being printed on dark backgrounds.

3. Adding too much 501PF Curable Reducer will diminish the film strength of the finished print and cause a phenomena called “fibrillation” where the fibre of the shirt stands up during the washing process and breaks through the ink film causing the print to look faded.

4. Fibrilation can also look like under-cure of the print. In order to determine if the print is “fibrillating” or “under-cured” simply wet your thumb or rub a wet cloth over the print. If the colours in the print darken and appear stronger or more vibrant the shirt is “fibrillating”. If the print looks the same after wetting it is under-cured and needs to be cured longer in your conveyor oven.

5. 501PF Curable Reducer can increase the chances for dye migration on 50/50 poly-cotton blends or 100% polyester fabrics and should not be added to any ink being printed on those type of fabrics. 1501PF SportPro Curable Reducer should be used instead.

Mixing & Testing

Always ensure that any additive mixed into Excalibur plastisol is very thoroughly mixed. We also highly recommend that test prints are done to ensure that all parameters are known and the required effect has been achieved prior to doing a production run.

Please note that these additives have been thoroughly tested in Excalibur plastisol ink and we cannot guarantee the same results if they are mixed with a competitive brand of plastisol ink.
