Method for coating wood

The invention relates to a method for coating wood with at least two water-based coating compositions, comprising: a) applying a coating composition A comprising at least one anionic polymer A having a Hansch parameter < = 1.6 and drying or allowing the water-based coating composition A to dry, a...

Beschreibung
Zusammenfassung:	The invention relates to a method for coating wood with at least two water-based coating compositions, comprising: a) applying a coating composition A comprising at least one anionic polymer A having a Hansch parameter < = 1.6 and drying or allowing the water-based coating composition A to dry, and b) applying a coating composition B containing at least one anionic polymer B having a Hansch parameter > = 1.7 and a pigment, and drying the aqueous coating composition B or allowing it to dry, with the proviso that the Hansch parameters of anionic polymer B and anionic polymer A differ by at least 0.5. The invention also relates to corresponding coated wood and to the use of a coating composition A comprising an aqueous anionic polymer A having a Hansch parameter < = 1.6 as a primer layer for coating wood. 本发明涉及一种用至少两种水基涂料组合物涂布木材的方法，该方法包括：a)施用包含至少一种Hansch参数≤1.6的阴离子聚合物A的涂料组合物A，并干燥所述水性涂料组合物A或允许其干燥，和b)施用含有至少一种Hansch参数≥1.7的阴离子聚合物B和颜料的涂料组合物B，并干燥所述水性涂料组合物B或允许其干燥，条件是阴离子聚合物B和阴离子聚合物A的Hansch参数相差至少0.5。本发明还涉及相应涂布的木材，以及涂料组合物A
