What is Aqueous Coating?

Aqueous coating is a fast-drying, water-based, vegetable cellulose product used as a protective coating which is applied in-line on press. It is biodegradable and recyclable. Aqueous coating is used for any project that requires a more durable finish, providing a high gloss surface which protects the surface from fingerprints, dirt, smudges, and scratches.

Aqueous coatings are applied to the printed sheet immediately after the inks. Directly after the coating is applied, the sheets are sent through a heated air system that quickly dries the coating. The printed sheets can progress to the finishing department in a matter of minutes, as opposed to traditional varnishes which may need hours or even days to dry.

Aqueous coating provides marvelous rub and scuff resistance. They give protection that far exceeds standard varnishes. It protects the product from harmful elements from the shipment through to end use.

How Aqueous Coating affects the environment?

Aqueous coating is generally considered to be one of the most sustainable coating options because the formulas are nontoxic in the pressroom, and treated paper can be recycled in standard municipal systems without emitting harmful byproducts. The cleanup process does not require toxic cleaning detergents nor does it necessitate high temperatures for drying.
