Disclosed is a method for providing a wood substrate with durability against weathering comprising at least two steps (A) and (B). Step (A) consists of applying to the wood substrate a transparent treatment comprising an organosilicon-containing compound having at least one hydrolyzable silyl group in a carrier for said compound. Step (B) consists of thereafter coating the wood substrate with a transparent, film-forming, coating composition. The coating composition is characterized in that a transparent free film from the coating composition retains an elongation of at least 20 percent after at least 1,000 hours exposure in a Xenon Weatherometer.
本发明公开了一种为木质基材提供抗风化耐久性的方法,该方法至少包括两个步骤(A)和(B)。 步骤(A)包括对木质基材进行透明处理,该处理包括在所述化合物的载体中使用含有至少一个可
水解
硅基的
有机硅化合物。 步骤(B)包括随后在木质基材上涂覆透明的成膜涂料组合物。 该涂料组合物的特征在于,在
氙风化仪中暴露至少 1,000 小时后,来自涂料组合物的透明游离膜的伸长率至少保持 20%。
