Add nylon catalyst to 222 Series or ELT Series ink for printing on waterproof or water resistant fabrics.  Using a scale, measure 10% nylon catalyst to 90% ink.  Once you have mixed the nylon catalyst, you only have a few hours before the ink will harden in the screen.  Be sure to clean the screens and squeegees immediately.

Important Notes:

* 10% nylon catalyst to 90% ink by weight
* Clean immediately after use
* For use on waterproof and water resistant items only
