General Technical Details:
This varnish has been formulated to provide a streak matt finish, whilst possessing suitable re-solubility characteristics making it recommended for double sided work and turn applications.
Back up times will depend however on substrate type, ink film weight and press conditions, although it is recommended that printed material has been left to set for at least 90 minutes prior to re-working.
1725 is suitable with testing for subsequent finishing operations such as foil blocking, gluing, lamination and UV varnishing. Certain recommendations will need to be followed if UV varnishing â€“ please contact us for further information
1736 has been formulated to provide excellent low curl and distortion characteristics. For this reason, 1725 can be employed as a sealer for light weight substrates. To reduce curl further, ensure paper has been suitably conditioned, and that press extraction is functioning.
Optimum drying conditions would include the use of hot air knives, and IR lamps. IR lamps should be kept to a minimum, with direct stack temperatures not falling below 27 Â°C or rise above 34 Â°C. For short runs, stack temperatures may not reach the optimum figures, and this must be considered if attempting to back up work rapidly.
Light application of a middle grade spray powder is recommended.
Storage and Handling:
Waterbased emulsions should not be exposed to temperatures below 5Â°C or above 35Â°C. During cold months, it is recommended that containers are kept off cold floors and stored on pallets. The shelf life of this coating is â€“ if unopened and stored in the correct conditions â€“ 12 months.
Waterbased emulsions are non hazardous and require no special storage or labelling.
