COATING COMPOSITION COMPRISING A VINYL MODIFIED ALKYD RESIN |
摘要 |
Coating composition comprising an alkyd having at least 20% by weight of vinylic building blocks and having an oil length below 65%. The weight ratio non-vinylic:vinylic groups is between 1:1 and 4:1, preferably between 1.5:1 and 3:1. The vinylic groups include styrene and (meth)acrylate groups. The ratio of styrene:(meth)acrylate groups is between 0.5:1 and 4:1, preferably between 1.5:1 and 3:1. The vinylic groups show low polarity. The Mw is below 10,000. The oil length is above 45%. The coating composition can be water borne or solvent borne. The alkyd according to the invention allows formulation of solvent borne coatings a volatile organic content below 300 g/l. |
