  • Alkyd resin composition comprising silica
    Patent number: 9932492
    Abstract: Disclosed is an oxidatively drying alkyd resin composition and a method for preparing said composition. Said composition is obtained by admixing an aqueous silica sol into a substantially 100% alkyd resin being in a liquid state either at ambient temperature or at an elevated temperature. Said silica sol is added in an amount of 0.1-10% by weight calculated as 100% silica on 100% alkyd resin. The use of a said composition is in a further aspect disclosed.
