Dehydran D Silicone-free compound containing hydroxyl groups Cognis Defoamer / Antifoaming agent >> Silicone-free >> Polymeric Epoxy Resins Coatings >> Waterborne Use Silicone-free defoamer for emulsion paints and water-emulsifiable epoxy resin paints. Composition Silicone-free compound containing hydroxyl groups. DEHYDRAN D may be used either to prevent the formation of foam or bubbles during the manufacture or application of the paint (by brush or roller), or to eliminate foam which has developed in the manufacturing process. This may be required e.g. when the formulation or production method have changed. DEHYDRAN D may be stirred into the paint at any stage of the production. They are generally added in undiluted form. Dosage is between 0.1 - 0.75%, calculated on total formulation. Non-ionic silicone-free defoamer for emulsion paints and water-emulsifiable epoxy resin paints. Can be used either to prevent the formation of foam or bubbles during the manufacture or application of the paint (by brush or roller), or to eliminate foam which has developed in the manufacturing process. This may be required e.g. when the formulation or production method have changed. Can be stirred into the paint at any stage of the production, generally added in undiluted form. Recommended usage level: 0.1 - 0.75%, calculated on total formulation.
