Mystery of Drying Aqueous Coatings
It’s well known and understood that washed clothing dries when the wash water is evaporated. Similarly, paint dries when the diluent solvent is evaporated, leaving a film of dry paint solids. Aqueous coatings dry as volatile components (mainly water), about 60% of the typical formula composition, evaporate or are absorbed by a porous substrate. Coalescence […]
Preprint Coatings
CORKOTE-25 Preprint Aqueous Coating CORKOTE- 25 is a zinc-free aqueous topcoat designed specifically for the pre-print process. It exhibits a moderate COF while providing the scuff resistance needed to withstand the hot corrugation process. CK-25 has exceptional abrasion and water resistant properties. Usage: CORKOTE- 25 is typically applied via flexo, gravure or roller-coater onto paper […]
