摘要:
Disclosed are methods for coating a substrate. These methods include: (a) preparing a two-component coating composition by mixing a first component and a second component to make a mixture thereof, and (b) depositing the mixture over the substrate to form a film having a 60° gloss of no more than 35 gloss units (measured according to ASTM D523-89). In these methods: (i) the first component includes: (A) an aqueous anionic, aliphatic polyurethane dispersion comprising a polyurethane having terminal methylol groups; and (ii) the second component comprises an aqueous anionic acrylic polymer solution having a viscosity of 25,000 to 60,000 mPa•s at 20 °C when measured according to DIN EN ISO 3219 at a non-volatile content of 9 % to 11 % by weight, based on the total weight of the solution, measured according to DIN 53189.
