Usage

Hardener (Catalyst)

Hardener no.2 (Catalyst) is added in an amount of 10% by weight to the ink or varnish. Mixing of the catalyst at different ratios will adversely affect the drying properties and the external strength.

The lifetime of the catalyst and ink mixture is about 72 hours at 20 ┬░ C.

Thinning

15-20% Thinner 10 is added to the ink and catalyst mixture. Due to the ambient conditions, thinner 10 can be replaced by retarder 4 or retarder 8 partly or wholly.

Protective Varnish

Application of the topcoat varnish on printing does not affect light transmittance but increases mechanical strength. 100T silk must be used during application.

The topcoat of protective varnish should be applied within 48 hours of the first printing.
