Abstract: An antimicrobial composition for use as a preservative for waterborne coating compositions where said antimicrobial composition comprise at least two organic compounds in combination selected from a combination of compound group i) and compound group ii). Compound group i) is selected from the group consisting of dodecanoic acid, metal dodecaonoate, ammonium dodecanoate and a combination thereof, while compound group ii) is selected from the group consisting of propionic acid, metal formate, metal propionate, ammonium propionate and a combination thereof. The waterborne coating composition is based on an emulsion polymer resin based on a radical polymerization polymer selected from the group consisting of; vinyl acetate (PVA) polymer, vinyl acetate/ethylene (VAE) copolymer, vinyl acrylic copolymer, acrylic polymer, styrene acrylic copolymer, vinyl acetate/ethylene/vinyl chloride copolymer, vinyl acetate versatate and combinations thereof. The antimicrobial composition constitutes 0.3-3.

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.
